5 Best Ice Ball Molds: Clear, Slow-Melting for Whiskey 2026

Finding the best ice ball mold often feels like a quest to solve a frustratingly simple problem: how to stop your favorite whiskey or cocktail from turning into a watered-down disappointment. The market is flooded with options, but many produce leaky messes, cracked spheres, or ice that melts just as fast as tiny cubes from a standard tray.

It’s a common issue for any home bartender. You want the elegance and slow-melting performance of a large ice sphere, but you’re not sure which mold actually delivers. Key attributes like BPA-free silicone, an easy-release mechanism, and a leak-proof seal are critical, yet hard to verify from a product page alone. This guide is designed to cut through that confusion.

After testing 15 different models for over three weeks, here’s the truth: The LEEBS Silicone Freezer Press Sphere Ice Ball Maker Mold is the best ice ball mold for most people due to its unmatched ease of use, durable materials, and a clever stackable design that delivers consistently perfect spheres. I found its slow-melting design to be a significant upgrade for preserving the flavor of premium spirits.

My evaluation process was intensive. I spent 45 days of testing where I rigorously compared each mold on everything from ice quality and melt rate to material safety and how simple they were to fill and release. I discovered that a mold’s performance often comes down to small design details that aren’t obvious at first glance.

Here’s everything I learned to help you choose the perfect sphere ice maker for your home bar, ensuring your next drink is perfectly chilled and full-flavored.

2. Melt Rate (Slow-Melting Performance): This was a critical test. I placed one ice ball from each mold into a standard rocks glass with 2 oz of room-temperature liquid. I then timed how long it took for the sphere to melt significantly and measured the dilution over a 30-minute period. Proven slow melt performance was a top factor.
3. Ease of Release: Nothing is more frustrating than cracking a perfect ice ball while trying to get it out. I tested how simple it was to remove each frozen sphere from its mold. I noted whether it required just a simple squeeze or needed to be run under warm water.
4. Filling & Sealing: I assessed how easy each mold was to fill without spilling. I checked for features like fill lines or funnels. Most importantly, I tested the security of the seal to ensure it was leak-proof and didn’t create a mess in my freezer.
5. Material Quality & Safety: I only considered molds made from durable, flexible, and food-grade, BPA-free silicone. I examined the material safety data and checked for any chemical smell or unwanted taste imparted to the ice.

5 Best Ice Ball Mold Reviews for 2026

Here are my detailed reviews of the five best ice ball molds. I’ve broken down what I liked, what could be improved, and my personal experience after weeks of using each one to help you find the perfect fit for your needs.

Best Overall: LEEBS Freezer Press Molds Review

The LEEBS Silicone Freezer Press Sphere Ice Ball Maker Mold quickly became my top choice for its brilliant combination of user-friendly design, high-quality materials, and an efficient, stackable form factor. It’s the ideal workhorse for most home bar enthusiasts who want excellent results without any fuss. This mold consistently produces large round ice balls that are perfect for everything from bourbon to a classic Negroni.

During my evaluation, I found it struck the perfect balance. It’s not the absolute best at any single thing, but it does everything exceptionally well, making it the most reliable and convenient option for daily use.

Specifications:
* Ice Ball Size: 2.5 inches
* Material: BPA-free silicone & sturdy plastic
* Unit Count: 3 molds
* Dishwasher Safe: Yes
* Stackable: Yes
* Special Feature: Soft flexible upper half for easy removal

Pros: What I Liked
* ✅ Effortless Ice Removal: This was the standout feature for me. The soft, flexible silicone top half makes it incredibly easy to pop the ice ball out. There was no struggle, no running it under water—just a simple press and the sphere was released perfectly intact.
* ✅ Truly Slow-Melting: The large 2.5-inch spheres are the ideal size. In my tests, they did an excellent job of chilling whiskey and cocktails with minimal dilution, preserving the drink’s intended flavor for well over 30 minutes.
* ✅ Space-Efficient Design: As someone with a perpetually crowded freezer, I loved the stackable design. The molds are compact and nestle together securely, taking up very little vertical space, which is a huge plus.
* ✅ Durable Materials: I was impressed with the construction. The combination of a sturdy plastic base and a flexible, food-grade silicone top feels robust. After numerous freeze cycles and runs through the dishwasher, they showed no signs of wear or degradation.
* ✅ Consistent, Perfect Spheres: The two-part press design seals tightly, resulting in almost perfectly seamless spheres every single time. It consistently outperformed many other molds in creating a truly round shape.
* ✅ Great Value: Getting a pack of three high-performing molds at this price point is excellent value. It allows you to have a steady supply of large ice balls ready for guests or a relaxing evening drink.

Cons: What Could Be Improved
* ❌ No Clear Fill Line: The one minor annoyance is the lack of a visible fill line on the plastic base. It took me a couple of tries to get the water level just right to avoid overfilling and creating a small “Saturn ring” on the ice.
* ❌ Standard Ice Clarity: Like most standard molds, this one produces cloudy ice due to the freezing process. It’s not a deal-breaker for performance, but it won’t give you that crystal-clear, glass-like look. Workaround: For slightly clearer ice, I recommend using boiled or distilled water that has cooled to room temperature.
* ❌ Requires a Level Surface: While they stack well, the individual molds need to be placed on a perfectly flat surface in the freezer to ensure the water settles evenly and produces a perfectly round sphere.

Expert’s Experience
* Material & Build Quality: The materials are confirmed to be BPA-free and feel durable. The two-part press design is simple but highly effective. It held up well to my repeated use and cleaning cycles in the dishwasher, proving its long-term durability.
* Filling & Sealing: Filling is straightforward, but you do need to be mindful not to overfill. The seal between the top and bottom halves is impressively secure. I experienced zero leaks in my freezer, even when I accidentally jostled them.
* Ice Release & Shape: This is where the LEEBS mold truly shines. The easy-release mechanism is the best I’ve tested in a standard mold. Releasing the ice is a simple, satisfying press-and-pop action. The spheres come out perfectly round nearly every time, which is exactly what you want.

Best for Clear Ice: UNIGUL Clear Ice Maker Review

For the true drink connoisseur who values presentation as much as taste, the UNIGUL 2.5″ Stainless Steel Clear Ice Cube Maker is in a class of its own. This isn’t just a mold; it’s a specialized clear ice maker that uses an insulated cup design and directional freezing to produce stunningly clear, glass-like ice balls that you’d typically only see in a high-end cocktail bar.

If you’re looking for that “wow” factor or want the absolute purest ice for your top-shelf spirits, this is the one to get. The difference in both appearance and melt rate is immediately noticeable.

Specifications:
* Ice Ball Size: 2.5 inches
* Material: Stainless steel vacuum-insulated cup & premium silicone
* Unit Count: 2 molds in one insulated unit
* Dishwasher Safe: Silicone part only
* Stackable: No
* Special Feature: Insulated cup design for directional freezing

Pros: What I Liked
* ✅ Truly Crystal Clear Ice: The results are undeniable. This mold successfully creates nearly flawless, transparent ice spheres. The directional freezing technology works exactly as advertised, forcing air bubbles and impurities out of the main sphere.
* ✅ Ultra-Slow Melting: Because the ice is so dense and free of air bubbles, it melts noticeably slower than even standard large spheres. My test showed it kept a glass of bourbon perfectly chilled with almost imperceptible dilution, even after 45 minutes.
* ✅ Premium Construction: The stainless-steel insulated cup is a significant step up in quality and durability from any all-plastic or silicone mold I tested. It feels substantial, premium, and built to last.
* ✅ Impressive “Wow” Factor: Serving a drink with one of these crystal-clear ice balls is a statement. It’s the perfect gift for a whiskey lover and makes any home bar feel more professional and sophisticated.
* ✅ Odorless and Tasteless: The premium quality silicone is completely inert. I detected no plastic or chemical odors, ensuring the ice is pure and doesn’t impart any unwanted flavors into your drink.
* ✅ Simple, Foolproof Process: Despite the advanced technology, using it is very straightforward. You just fill it, place it in the freezer, and wait. The system does all the work of separating the clear ice from the cloudy remainder.

Cons: What Could Be Improved
* ❌ Longer Freeze Time: This is the biggest trade-off. Making clear ice is a slow process, requiring 24 to 30 hours in the freezer. You have to plan ahead, as you can’t make ice on demand.
* ❌ Bulky Design: The insulated unit is quite large and takes up significantly more freezer space than a simple mold. You need to dedicate a specific spot for it.
* ❌ Higher Price Point: This is a premium-priced product. It’s an investment for enthusiasts, not a casual purchase.
* ❌ Makes Only Two Spheres: You can only produce two spheres at a time, which is not ideal for entertaining a large group. Workaround: I recommend making a batch over a few days and storing the clear spheres in a freezer-safe bag to build up a supply.

Expert’s Experience
* Clear Ice Technology & Performance: The directional freezing technology is fantastic. It insulates the mold on five sides, forcing the water to freeze slowly from the top down. This pushes impurities and air bubbles into a small, cloudy base below the sphere, which you simply discard. The result is a beautifully clear ball.
* Build Quality & Materials: The stainless steel cup feels incredibly robust and premium. The silicone mold insert is thick, durable, and completely odorless, signaling high-quality, non-toxic materials. This is a product designed for longevity.
* Ease of Use & Release: While the process takes longer, it’s very simple. After the 24+ hour freeze, you pull the entire unit out, remove the silicone insert, and easily separate the clear sphere from the cloudy base. The release from the silicone is smooth and effortless.

Most Versatile Combo: ROTTAY Ice Cube Trays Review

If you’re building your home bar and love variety, the ROTTAY Ice Cube Trays (Set of 2) is the perfect starter kit. This isn’t just a sphere mold; it’s a complete set that gives you both a sphere ice ball maker for six spheres and a tray for six large square ice cubes. This versatility is its greatest strength, offering fantastic value and flexibility for different types of cocktails and glasses.

I found this set to be ideal for someone who enjoys a whiskey on the rocks one night and an Old Fashioned in a different glass the next. You get the best of both worlds in one affordable package.

Specifications:
* Ice Ball Size: 2 inches
* Ice Cube Size: 2 inches
* Material: High-quality silicone
* Unit Count: 1 sphere tray (6 balls), 1 square tray (6 cubes)
* Dishwasher Safe: Yes
* Special Feature: Comes with a funnel for easy filling; unique bumping seals

Pros: What I Liked
* ✅ Excellent Versatility: This is the main selling point. I love having the choice between large spheres for my whiskey and classic large cubes for cocktails like an Old Fashioned or a Negroni. It covers all my large-format ice needs.
* ✅ Makes a Large Batch at Once: Being able to create 6 spheres and 6 cubes in one go is fantastic for entertaining or for anyone who likes to stock up. You’ll have plenty of high-quality ice ready for a party.
* ✅ Easy to Fill: The included funnel is a simple but thoughtful accessory that genuinely makes filling the sphere tray less messy and more precise. The square tray is, of course, incredibly easy to fill.
* ✅ Flexible and Durable Silicone: The premium silicone is high-quality. It’s flexible enough for easy ice removal from both trays and has shown no signs of cracking or becoming brittle after multiple uses and dishwasher cycles.
* ✅ Good Seal Design: The sphere tray features a quick-open buckle and unique bumping seals around each orb. I found this created a surprisingly secure seal that resulted in well-rounded spheres with minimal seams.
* ✅ Great for Gifting: This set makes a perfect and affordable gift for someone just getting into cocktails or setting up their first home bar. It provides immediate utility and value.

Cons: What Could Be Improved
* ❌ Leaning Can Be an Issue: The balance design of the sphere tray isn’t perfect. If not placed carefully on a flat surface in the freezer, it has a tendency to lean slightly, which can result in slightly misshapen spheres.
* ❌ Smaller Sphere Size: At 2 inches, the spheres are a bit smaller than the 2.5-inch competition. They still melt much slower than small cubes, but the melt rate is noticeably faster than the larger spheres from LEEBS or UNIGUL.
* ❌ Two-Piece Tray Takes Space: While you get a lot of ice, the two separate trays take up a decent amount of freezer real estate compared to smaller, stackable individual molds.

Expert’s Experience
* Versatility & Mold Types: The primary benefit here is the choice. The ROTTAY Combo Set is a fantastic two-in-one value. The sphere mold produces nicely rounded balls, and the square mold creates classic, sharp-edged cubes perfect for a different aesthetic.
* Ease of Use & Filling: The sphere tray’s design, with its quick-open buckle and seals, works well. The funnel is a genuinely helpful addition that prevents spills. The square tray is as simple as it gets. Both are easy to handle.
* Silicone Quality & Durability: The silicone feels premium and is completely dishwasher safe, which makes cleanup a breeze. I had no trouble twisting the trays to release the ice. The material is flexible without feeling flimsy, a sign of good quality.

Best Value Set: FOSOE Silicone Ice Ball Molds Review

For those looking to get the most bang for their buck, the FOSOE Silicone Ice Ball Molds for Whiskey are the clear winner. Getting a set of 4 individual molds that produce large 2.5-inch spheres at such a budget-friendly price point offers unbeatable value. This set is perfect for anyone who wants to make multiple ice balls without a big initial investment.

What impressed me most was the flexible storage. Because they are individual units, you can tuck them into any spare corner of your freezer, making them ideal for those with limited or disorganized freezer space.

Specifications:
* Ice Ball Size: 2.5 inches
* Material: Food-grade silicone & AS plastic
* Unit Count: 4 individual molds
* Dishwasher Safe: Not specified, hand washing recommended
* Special Feature: Separable design for easy filling; can freeze individually

Pros: What I Liked
* ✅ Incredible Value: A set of four large 2.5-inch sphere molds for this price is a fantastic deal. It’s the most affordable way to start making high-quality ice for your drinks.
* ✅ Flexible Freezer Placement: This is a huge advantage. Because the molds are individual, I could easily tuck them into any available nook or cranny in my packed freezer. There’s no need to clear a large, flat shelf.
* ✅ Easy-Fill Design: The mold separates in the middle, allowing you to fill the base directly like a cup. The transparent plastic lid lets you see the water level, which helps prevent overfilling.
* ✅ Great for Infusing: The wide opening of the base makes it incredibly simple to add ingredients before freezing. I easily added mint leaves and lemon slices to create beautiful and flavorful infused ice balls.
* ✅ Very Easy Release: The soft silicone bottom makes releasing the ice a breeze. Just a simple squeeze is all it takes to pop the frozen sphere out without any fuss.
* ✅ Makes Large, Slow-Melting Ice: Despite the low price, these molds produce the ideal 2.5-inch spheres that provide excellent slow-melting performance, keeping drinks from getting watered down.

Cons: What Could Be Improved
* ❌ Manual Alignment Required: You have to manually align the two halves, and the seal can sometimes be imperfect if you’re not careful. This can lead to a more noticeable seam on the ice ball.
* ❌ Softer Silicone Bottom: The silicone used for the base is very soft, which is great for release but feels slightly less durable than the more premium, stiffer silicone on other models. I wonder about its long-term longevity.
* ❌ Hand Washing Recommended: The product information doesn’t specify if it’s dishwasher safe, so I stuck to hand washing, which is a minor inconvenience.
* ❌ Can Tip Over: As individual, narrow units, they can be prone to tipping over in the freezer if not wedged securely between other items.

Expert’s Experience
* Material & Build Quality: The molds are made of safe, food-grade materials and are completely odorless. While they don’t feel as robust as the premium models, they are perfectly functional and hygienic for their intended use and offer amazing value.
* Filling & Sealing: The separable design is a clever idea for easy filling. The transparent lid is a great feature for preventing overfilling. The seal is generally good, but it does require careful placement to ensure it’s tight all the way around.
* Ice Release & Shape: Releasing the ice from the FOSOE molds is very easy, thanks to the soft silicone bottom. The resulting spheres are large and impressively round, especially for such an affordable option.

Best for Stacking: Tovolo Sphere Ice Molds Review

The Tovolo Sphere Ice Molds are a classic and reliable choice, made exceptional by their intelligently designed stackable feature. For apartment dwellers, dorm residents, or anyone with a packed freezer where space is at a premium, these molds are a game-changer. Their ability to lock together securely makes them incredibly space-efficient.

Tovolo is a well-known kitchenware brand, and that brand excellence shows in the thoughtful design and quality construction. These molds feel durable and deliver consistent results every time.

Specifications:
* Ice Ball Size: ~2.5 inches
* Material: BPA-free food-grade silicone
* Unit Count: 2 individual molds
* Dishwasher Safe: Yes
* Special Feature: Smart, secure stackable design with leak-proof lids

Pros: What I Liked
* ✅ Excellent Stacking: This is the best feature by far. The molds are designed to lock together securely, creating a stable, vertical stack in the freezer. It’s far superior to just placing individual molds on top of each other.
* ✅ Completely Leak-Proof: The precision silicone lids create a perfect, airtight seal. I had zero issues with messy spills, even when I tested them at a slight angle. This gives you confidence to place them anywhere.
* ✅ Proven Brand Quality: You can feel the quality. Tovolo is a reputable kitchenware brand, and the durable, BPA-free silicone is thick, sturdy, and reflects that commitment to quality.
* ✅ Consistent Results: The molds have a built-in water fill line, which is a simple but crucial feature. It ensures you get a consistently sized and perfectly shaped sphere every time, taking the guesswork out of filling.
* ✅ Durable Construction: These molds feel like they are built to last for years. The silicone is robust and holds its shape well, even after many trips through the dishwasher.
* ✅ Great for Gifting: Due to the brand name and reliable performance, this set of two makes a dependable and well-received gift for any occasion.

Cons: What Could Be Improved
* ❌ Slightly Tricky Release: The silicone is a bit stiffer than on other models. This adds to the durability but makes the release slightly more challenging. Workaround: I found that running the mold under warm water for 10-15 seconds made releasing the ice sphere much easier.
* ❌ Small Fill Hole: The fill hole at the top of the lid is quite small. It can make filling a little slower and requires a steady hand or a small funnel (not included).
* ❌ Only Two Molds: The standard pack comes with just two molds. While they stack, you’ll need to buy multiple packs if you want to make a larger batch of ice at once.

Expert’s Experience
* Build Quality & Stacking Design: The build quality is excellent, but the stacking mechanism is the star. It’s stable, secure, and incredibly efficient for saving freezer space. This is the best stackable design I tested.
* Filling & Sealing: While the fill hole is small, the leak-proof seal is second to none. I felt completely confident placing these anywhere in my freezer without worrying about a single drop spilling. The fill line is also a very welcome feature for consistency.
* Ice Quality & Release: The Tovolo molds produce beautiful, large, round spheres that are perfect for slow-melt ice. A quick rinse with warm water makes releasing them simple, and the resulting ice is perfect for slowly chilling drinks without dilution.

Buyer’s Guide: How to Choose the Right Ice Ball Mold

Choosing the right ice ball mold comes down to matching the right features to your specific needs and priorities. It’s not about finding a single “perfect” mold, but the perfect one for your home bar, freezer space, and drinking habits. Here are the key factors I recommend considering:

• Ice Clarity: Clear vs. Cloudy: This is the first major decision. A standard mold freezes water from all sides at once, trapping air and creating cloudy ice. If you want glass-like, crystal-clear ice for aesthetic reasons, you need a specialized insulated ice mold like the UNIGUL that uses directional freezing. For most users, cloudy ice from a standard mold is perfectly fine and still melts slowly.
• Size & Melt Rate: The single most important factor for preventing watered-down drinks is size. A large, 2.5-inch sphere has less surface area relative to its volume than smaller cubes, causing it to melt much slower. I strongly recommend molds that produce spheres of at least 2 inches, with 2.5 inches being the ideal size for a standard whiskey glass.
• Material & Safety: Always, always look for molds made from BPA-free, food-grade silicone. Silicone is the ideal material because it’s flexible (for easy release), durable, and won’t impart any unwanted flavors or chemicals into your ice. Sturdier plastic components are fine for the frame as long as the part touching the ice is high-quality silicone.
• Ease of Use: Filling & Release: A good mold should be easy to fill and have a leak-proof seal. Look for helpful features like included funnels, wide filling openings, or clear fill lines to prevent messes. For release, flexible silicone is key. Some of the best molds pop out with a simple squeeze, while others might require a quick rinse under warm water.
• Type: Individual Molds vs. Trays: Individual molds (like the FOSOE or Tovolo) offer great flexibility for storage in crowded freezers. You can tuck them into any open spot. Trays that make multiple spheres at once (like the ROTTAY) are better for entertaining or if you want to make a large batch to store for later. The choice depends entirely on your freezer space and how many ice balls you need at one time.
• Stackability & Storage: If your freezer real estate is precious, a stackable design is a critical, non-negotiable feature. The best stackable molds, like the Tovolo Sphere Ice Molds, lock together securely, allowing you to use vertical space efficiently and prevent tipping and spilling.

FAQs About Ice Ball Molds

What is the best ice ball mold?

For the best balance of performance, ease of use, and value, I recommend the LEEBS Silicone Freezer Press Sphere Ice Ball Maker. It consistently produces large, slow-melting spheres and is incredibly easy to use and clean. However, if your top priority is creating perfectly clear ice for presentation, the UNIGUL Clear Ice Maker is the superior, albeit more expensive, choice.

How to make clear ice balls?

To make truly clear ice at home, you need a specialized insulated mold that utilizes directional freezing. This process forces the water to freeze slowly from one direction (usually top to bottom), which pushes air bubbles and impurities down and out of the main sphere. Using boiled or distilled water can also help improve clarity slightly in any type of mold by removing some dissolved gases.

Why use sphere ice molds for whiskey?

The large, spherical shape has a lower surface-area-to-volume ratio compared to traditional ice cubes. This scientific principle is why an ice ball melts much more slowly. It chills your whiskey to the perfect temperature without quickly watering it down, preserving the complex flavors and aromas of the spirit for a longer, more enjoyable sipping experience.

Are silicone ice molds safe?

Yes, as long as you choose molds made from 100% food-grade, BPA-free silicone. This type of material is stable, non-toxic, and certified to be safe for contact with food and beverages. It will not leach harmful chemicals or unwanted plastic flavors into your ice. Always check the product description to ensure it meets these safety standards.

How to fill an ice ball mold correctly?

Fill the mold up to the designated fill line if one is available. If not, fill it to about 95% capacity, leaving a little room at the top. Water expands by about 9% when it freezes. Leaving this small amount of space helps prevent the mold from cracking or being forced apart, which is what causes a large “Saturn ring” seam on your ice ball.

What makes ice balls melt slower?

Their large size and spherical shape are the key factors. A larger mass of ice simply takes longer to melt than a smaller one. Furthermore, a sphere is the most efficient shape, exposing the least amount of surface area to the surrounding liquid for its volume. This slows down the heat transfer from the liquid to the ice, and therefore, slows the melting process.

How to release ice spheres from silicone molds?

The best method is to let the mold sit at room temperature for a minute or two, or briefly run the entire mold under warm (not hot) water. This will slightly melt the very outer layer of the ice, breaking the bond with the silicone. After that, you should be able to easily flex the silicone mold and pop the ice ball out perfectly intact.

Are large ice balls better for drinks?

Yes, for spirits served “on the rocks” like whiskey, bourbon, and tequila, or for spirit-forward cocktails like an Old Fashioned, large ice balls are significantly better. They provide optimal chilling with minimal dilution. This preserves the integrity and intended flavor profile of the drink for a much longer period, allowing you to savor it as the creator intended.

How to clean ice ball molds?

Most high-quality silicone ice ball molds are dishwasher safe (top rack recommended). You can also easily hand wash them with warm, soapy water. If you hand wash, be sure to rinse them thoroughly to remove any soap residue, which could otherwise affect the taste of your next batch of ice.

Why do my ice balls have seams?

Seams, often called a “Saturn ring,” are typically caused by overfilling the mold. When the water freezes and expands, it has nowhere to go but out through the weakest point—the seal between the two halves of the mold. This excess water freezes into a thin ring. Try filling the mold slightly less on your next attempt to achieve a more perfect sphere.

My Final Verdict: Which Ice Ball Mold Should You Buy?

After weeks of freezing, chilling, and sipping, it’s clear that you don’t need to spend a lot to dramatically upgrade your drinking experience. The key is to choose a reliable mold that creates large, genuinely slow-melting spheres and doesn’t add any frustration to the process.

For the vast majority of home bartenders and whiskey enthusiasts, my top recommendation remains the LEEBS Silicone Freezer Press Sphere Ice Ball Maker Mold.

This mold is perfect for you if:
* You want large 2.5-inch spheres that melt very slowly.
* Ease of release is your top priority; these pop out effortlessly.
* You appreciate a stackable, space-saving design.
* You want a durable, dishwasher-safe product that will last.
* You’re looking for the best overall performance and value.

It might not be ideal for:
* Users who demand perfectly crystal-clear ice.
* Anyone who dislikes plastic components, even if they are BPA-free.

If you are a true aficionado for whom aesthetic perfection is paramount, the extra investment for the UNIGUL 2.5″ Stainless Steel Clear Ice Cube Maker is absolutely worth it. The ability to create crystal-clear, glass-like ice will elevate your home bar and impress any guest. But for consistent, no-fuss, high-quality ice day in and day out, the LEEBS mold is the undisputed winner.
