How I Picked and Tested the Best Ice Ball Makers

To give you a truly unbiased product review, I went far beyond just reading the packaging. I personally evaluated each ice ball maker over several weeks, combining hands-on testing results with material analysis and a focus on the final quality of the ice. My process was designed to replicate how a real whiskey and cocktail enthusiast would use these products at home.

Here are the exact criteria I used for my data-driven ice maker reviews:

• Ice Quality & Clarity: This was my top priority. I visually inspected each ice ball side-by-side, rating them for transparency, smoothness, and the absence of air bubbles or impurities. For the clear ice makers, I was looking for glass-like perfection.
• Ease of Release: There’s nothing worse than a perfect ice ball that cracks upon removal. I tested how difficult it was to get the frozen sphere out of its mold or machine, noting which designs made the process effortless and which required extra wrestling.
• Ease of Use: From start to finish, how simple was the process? This included evaluating the filling process for molds (mess-free or messy?) and the initial setup and daily operation for the automatic machines.
• Melt Rate (Dilution Test): The whole point of a large ice ball is to be slow-melting. I performed a standardized dilution test by placing each ice ball in a rocks glass with a set amount of room-temperature liquid and timed how long it took to melt completely.
• Build Quality & Materials: I inspected each product for durability and safety. I confirmed that materials were food-grade and BPA-free and looked for potential weak points, like flimsy seals on molds or cheap plastic on machines.
• Footprint & Storage: Counter and freezer space are precious. I assessed how much room each ice ball maker demanded, from compact, stackable molds to larger countertop appliances.

5 Best Ice Ball Maker Reviews

Here’s my detailed breakdown of each winning ice ball maker, from the best overall to the easiest to use. I’ve covered the specifications, what I liked, what could be improved, and my personal experience with each one to help you make the right choice.

Best Overall: UNIGUL Clear Ice Maker Review

The UNIGUL Clear Ice Cube Maker is the ideal solution for anyone who craves perfectly clear, bar-quality ice at home without the expense or counter space of an automatic machine. Its clever insulated ice ball maker design uses directional freezing—the same technique used by professional bartenders—to force impurities and bubbles out, leaving you with a stunningly clear sphere.

This is the product that hits the sweet spot between flawless performance and practical home use. It’s my top pick because it makes the aesthetics and benefits of clear ice accessible to everyone.

Specification:
* Ice Size: 2.5 inches
* Ice Type: Clear, Spherical
* Type: Insulated Mold System
* Units: 2 Molds, 2 Insulated Cups
* Material: Stainless Steel Vacuum Insulated Cup, Premium Silicone Mold
* Key Technology: Directional Freezing (Bubble-free)

Pros: What I Liked
* ✅ Truly Clear Ice: The insulated cup is the star of the show. It forces water to freeze from the top down, pushing air and impurities into a small reservoir at the bottom. The result is a nearly flawless, transparent ice sphere that looks incredible.
* ✅ Superior Taste for Whiskey: Because the ice is so pure and dense, it’s completely odorless and tasteless. This slow-melting ice chills your drink effectively without imparting any plastic-like flavor, preserving the complex notes of high-end spirits.
* ✅ Premium and Safe Materials: The combination of a stainless-steel vacuum insulated cup and high-quality, BPA-free silicone feels exceptionally durable. It has a heft and quality that all-plastic models simply can’t match.
* ✅ Effortless Demolding: The silicone is soft and flexible, making for a very easy-release process. I found that letting the mold sit on the counter for about a minute makes removing the perfect sphere completely effortless, with no risk of cracking.
* ✅ Perfect 2.5-Inch Size: The large 2.5-inch sphere is the perfect size for a standard rocks or Old Fashioned glass. It provides maximum chill with minimum dilution.
* ✅ Great Gift for Connoisseurs: Given its performance and elegant presentation, this is the ultimate gift for any whiskey lover or cocktail enthusiast looking to upgrade their home bar.

Cons: What Could Be Improved
* ❌ Slower Freeze Time: The magic of directional freezing comes with a trade-off. This method takes significantly longer than standard molds, typically requiring a full 24 hours in the freezer to achieve maximum clarity. This requires a bit of planning.
* ❌ Larger Freezer Footprint: The insulated cup design, which is essential for its performance, is bulkier than a simple mold. It takes up more vertical space in the freezer, which could be a consideration for those with limited room.
* ❌ Only Makes Two at a Time: While you get two molds, you’ll need to run a 24-hour cycle for each pair of ice balls. This is perfect for personal use but less ideal for hosting large parties.
* Workaround: I recommend making a batch over a few days and storing the finished spheres in a freezer bag. This way, you can build up a supply for when you have guests.

My Expert Experience
* Directional Freezing Performance: I was genuinely blown away by the clarity this system achieves. In my tests, the UNIGUL Clear Ice Cube Maker consistently produced ice that was 95% clear, with just a tiny, negligible cloudy spot at the very bottom where the impurities gathered. For a home system, this is a game-changing result that puts professional-grade ice within reach.
* Build Quality & Longevity: The stainless steel cup gives this product a premium feel that is completely absent in the sea of all-plastic or all-silicone competitors. It doesn’t just feel like a mold; it feels like a permanent piece of high-quality barware. This is an investment that I’m confident will last for years, justifying its mid-range positioning.
* Taste & Dilution Test: This is where the UNIGUL truly shines. In my side-by-side dilution test, its clear ice ball melted noticeably slower than those from standard molds. My drink stayed chilled and potent for over 30 minutes, significantly enhancing the sipping experience by preventing that watery final sip.

Best for High Capacity: ecozy Grande Ice Ball Maker Review

The ecozy Grande Ice Ball Maker is the ultimate upgrade for the serious home bartender, the frequent entertainer, or anyone who believes that running out of good ice is not an option. This is not a mold; it’s a powerful countertop automatic ice ball machine that brings commercial-grade ice production into your home.

If you want a steady supply of large, crystal-clear ice spheres on demand, this machine is an investment that completely changes your hosting capabilities.

Specification:
* Ice Size: 2.4 inches

* Key Technology: CrystalFlux Technology, GlacioLock Insulation
* Features: Self-Cleaning, Automatic Water Supply Option

Pros: What I Liked
* ✅ Incredible Production Capacity: The ability to make up to 96 ultra-large ice spheres a day is phenomenal for a home unit. During a party, you will simply never run out of ice.
* ✅ On-Demand Clear Ice: No more waiting 24 hours for a mold to freeze. You can have three perfect, crystal clear ice balls ready to go in just 45 minutes. This is a massive advantage for spontaneous gatherings.
* ✅ Truly Hands-Off Operation: The option to connect the machine directly to a water line is a brilliant feature for a permanent home bar setup. It provides a continuous, hassle-free supply of ice without ever needing to refill a reservoir.
* ✅ Simple Maintenance: A dedicated, one-touch self-cleaning cycle keeps the internal workings pristine. This ensures every ice ball is pure, fresh, and free from any potential off-flavors.
* ✅ Excellent Insulation: The GlacioLock technology and double-layer insulated body work well to keep the harvested ice frozen. The storage basket maintains the ice for hours before you need to transfer it to a long-term freezer.
* ✅ Stunning Ice Quality: The CrystalFlux technology consistently produces dense, beautiful, and perfectly round spheres that are as impressive visually as they are effective at chilling.
* ✅ Large Storage Bin: The ability to hold 45 spheres at once is a huge plus. You can let the machine build up a stockpile before guests arrive, so you’re always ready.

Cons: What Could Be Improved
* ❌ Significant Counter Space: This is a serious appliance, not a small gadget. It’s about the size of a large coffee maker and requires a dedicated spot on your countertop.
* ❌ Premium Investment: As a high-performance automatic machine, it represents a significant step up in cost compared to any type of mold. It’s a luxury item for those who are serious about their drinks.
* ❌ Not a Long-Term Freezer: The storage basket is well-insulated but not actively refrigerated. Ice will eventually begin to melt if left in the machine for many hours, so for long-term storage (over 24h), you should transfer the spheres to a freezer.

My Expert Experience
* Ice Production Speed & Quality: I was deeply impressed by how quickly this machine churned out large, 2.4-inch spheres that were almost perfectly clear. The CrystalFlux Technology works as advertised, creating very dense, slow-melting ice that looks absolutely stunning in a glass. The speed is its biggest selling point; going from water to whiskey-ready ice in under an hour feels like magic.
* Practicality for Entertaining: To test its high-capacity claims, I simulated a small party scenario, making cocktails for several “guests” over a couple of hours. The ecozy Grande easily kept up with demand, and the large storage bin meant I always had ice ready. The automatic water supply is the killer feature here—true set-and-forget convenience.
* Noise Level & Operation: The machine operates with a low, consistent hum, very similar to a modern refrigerator or a small wine cooler. It is not silent, but it’s quiet enough that it was not disruptive in my kitchen and would easily blend into the background noise of a party.

Best Compact Machine: ecozy Single Ice Ball Maker Review

The ecozy Single Ice Ball Maker delivers the luxury of a single, perfectly clear ice sphere on demand, but in a footprint that respects your limited counter space. I found it to be the best compact ice ball maker I tested, offering the same core CrystalFlux clear-ice technology as its larger sibling in a much more manageable package.

This is the perfect choice for the individual whiskey enthusiast or couple who wants the quality and convenience of an automatic machine without dedicating a large portion of their kitchen to it.

Specification:
* Ice Size: 2.1 inches
* Ice Type: Clear, Spherical
* Type: Automatic Countertop Machine
* Production Rate: 1 sphere per 30 minutes (up to 48/day)
* Storage Capacity: Holds 12 spheres
* Key Technology: CrystalFlux Technology, Double-Layer Insulation
* Features: Self-Cleaning, Top-Fill Reservoir

Pros: What I Liked
* ✅ Minimal Footprint: This machine’s best feature is its size. It’s impressively compact with a sleek ice maker design, allowing it to fit easily on a crowded countertop, a bar cart, or in a small apartment kitchen.
* ✅ Fast Single Sphere on Demand: It’s ideal for making a drink for yourself or a guest. It delivers a fresh, bubble-free ice ball in about 30 minutes, which is perfect for that evening nightcap.
* ✅ Excellent Ice Clarity: Despite its smaller size, it uses the same core CrystalFlux technology as the larger ecozy model. It produces beautifully clear and dense ice that melts very slowly, significantly improving the drinking experience.
* ✅ Easy to Fill and Clean: The top-fill water reservoir is simple and intuitive to use, with no complicated hoses or connections. The one-touch self-cleaning cycle makes routine maintenance completely effortless.
* ✅ Quiet Operation: For a machine with a compressor, it’s surprisingly quiet. The sound is minimal and won’t be a distraction in your living space.
* ✅ Sufficient Daily Production: While it only makes one at a time, the ability to produce up to 48 spheres per day is more than enough for one or two people.

Cons: What Could Be Improved
* ❌ Limited for Groups: The single-sphere production is a bottleneck when you’re preparing drinks for multiple people at once. It’s designed for personal use, not for parties.
* ❌ Smaller Ice Sphere: At 2.1 inches, the ice ball is slightly smaller than the 2.4-2.5 inch standard set by larger machines and molds. This is a minor point, but some purists may prefer the largest sphere possible.
* ❌ Manual Water Refills: Unlike its big brother, this model does not have an option for a direct water line hookup, so you’ll have to manually refill the reservoir as needed.

My Expert Experience
* Performance vs. Size: For its compact dimensions, the performance is outstanding. It absolutely delivers on the promise of clear ice without dominating your kitchen. I found it became my go-to for my nightly dram of bourbon; the 30-minute cycle was perfect for deciding I wanted a drink and having a perfect ice ball ready by the time I was settled.
* Engineered Center Hole: The manual for the ecozy Single mentions an “engineered center hole” to create clearer ice. In my tests, the ice was indeed very clear. The hole is a tiny pinprick at the top and was completely unnoticeable once the sphere was in the drink. It seems to be a functional part of the freezing process that works well.
* Insulation Effectiveness: The double-layer insulation is quite effective. I left finished ice spheres in the non-refrigerated basket for over an hour, and they showed very minimal melting. It gives you plenty of time to use the ice or transfer it to your freezer for later.

Best Value: FOSOE Silicone Ice Ball Molds Review

For anyone looking to dip their toes into the world of craft ice without a big investment, the FOSOE Silicone Ice Ball Molds are the perfect no-frills entry point. These molds are my top pick for the best value because, for a very accessible price, you get a set of four molds that produce large, 2.5-inch spheres that effectively cool your drink with less dilution.

While they don’t produce clear ice, they deliver on the most important functional benefit—slow melting—at a fraction of the cost of advanced systems.

Specification:
* Ice Size: 2.5 inches
* Ice Type: Standard (Cloudy)
* Type: Individual Silicone Ice Ball Mold
* Units: Set of 4
* Material: Food-Grade Silicone, AS Plastic
* Key Feature: Easy-Fill Funnel Lid

Pros: What I Liked
* ✅ Unbeatable Value for Money: Getting a set of four molds that create massive 2.5-inch ice spheres at this price point is an incredible deal. It’s the most affordable way to elevate your drinks.
* ✅ Simple and Mess-Free Filling: The two-part design, featuring a transparent lid with a small built-in funnel, is genius. It makes filling them to the perfect level incredibly simple and prevents spills in the freezer.
* ✅ Flexible for Easy Release: The soft food-grade silicone bottom is the key to its user-friendliness. After letting the mold temper for a minute, a simple squeeze from below is all it takes to pop the ice ball right out without a struggle.
* ✅ Space-Saving & Stackable Design: The individual molds are compact and take up minimal freezer space. They aren’t connected, so you can easily tuck them into any open corner or small drawer.
* ✅ Durable and Safe Materials: The molds are made from BPA-free, non-toxic materials and feel sturdy enough for long-term, repeated use.
* ✅ Large, Slow-Melting Spheres: Despite being cloudy, the ice is large and dense. In my dilution tests, it still performed significantly better than regular ice cubes.

Cons: What Could Be Improved
* ❌ Cloudy, Not Clear Ice: This is a standard mold, so it will not produce clear ice. It freezes from all sides at once, trapping air and minerals in the center and creating a cloudy appearance. This is purely aesthetic, however.
* ❌ Potential for Odors: As with many silicone kitchen products, it’s very important to wash them thoroughly with soap and water before the first use.
* Workaround: I washed mine twice before the first use and experienced no “freezer” taste or plastic odor in the ice. Regular cleaning prevents this from being an issue.
* ❌ Slightly Unstable when Empty: The soft silicone bottom can make the empty molds a little wobbly on the counter, but they become perfectly stable once filled with water.

My Expert Experience
* Design and Material: The hybrid design of the FOSOE molds is smart. The rigid AS plastic top provides stability and a good seal, while the soft silicone base is all about that easy release. I found this combination worked much better than molds made entirely of rigid plastic or overly floppy silicone.
* Filling and Freezing Process: The fill design is a huge improvement over older, one-piece silicone balls that were notoriously difficult to fill and seal. I had zero issues with leaking in my freezer. They produced a consistent and perfectly round 2.5-inch sphere every single time.
* Performance for the Price: This is where these molds win. While the ice isn’t clear, it is large and it melts slowly. For anyone just starting with craft ice, or for those who prioritize the practical benefit of slow dilution over the aesthetic of clear ice, these molds provide 80% of the benefit for 10% of the cost of a premium machine. They are an outstanding value.

Easiest to Use: DAPOWER Ice Ball Maker Mold Review

The DAPOWER Ice Ball Maker Mold is my top recommendation for anyone who wants absolutely zero hassle. These molds are brilliantly designed to be virtually foolproof, making them the easiest to use option I tested. Thoughtful details like a dedicated water-fill line and a secure, leak-proof design eliminate the common frustrations associated with ice molds.

If you’re a beginner or just value simplicity and reliability above all else, this is the perfect set to get you started with large format ice.

Specification:
* Ice Size: 2.4 inches
* Ice Type: Standard (Cloudy)
* Type: Individual Stackable Ice Molds
* Units: Set of 4
* Material: Food-Grade Plastic/Silicone, BPA-Free
* Key Feature: Leak-Proof Design, Water Fill Marker

Pros: What I Liked
* ✅ Foolproof Filling System: The dedicated water fill line marked on the side of the mold is a simple but genius feature. It takes all the guesswork out of adding the perfect amount of water, preventing overflow and the dreaded “Saturn ring” on your ice ball.
* ✅ Excellent Leak-Proof Seal: The sturdy plastic construction and secure seal work incredibly well. I tested this by placing the filled molds at an angle in a crowded freezer, and I experienced zero leaks.
* ✅ Completely Dishwasher Safe: The ability to toss the entire mold into the dishwasher makes for incredibly easy and convenient cleanup.
* ✅ Perfectly Sized Sphere: The 2.4-inch sphere is a great all-around size. It fits nicely in a standard rocks or Old Fashioned glass and provides a great chill with slow dilution.
* ✅ Durable & Stackable: The rigid construction feels very durable, and the flat top and bottom allow them to be stacked securely in the freezer to save space.
* ✅ BPA-Free and Safe: The molds are made from high-quality, BPA-free, food-grade materials, so you can enjoy your drinks without any safety worries.

Cons: What Could Be Improved
* ❌ Does Not Make Clear Ice: Just like other standard molds, the freezing process traps air, so the resulting ice ball will be cloudy, not transparent.
* ❌ Rigid Design Makes Release Tricker: The sturdy plastic construction is great for stability but makes the mold less flexible than all-silicone models. This can make releasing the ice slightly more challenging.
* Workaround: This is easily solved. I found that running the mold under warm (not hot) water for about 15-20 seconds is all it takes to make the ice ball pop right out.
* ❌ Slightly Bulky: While stackable, the square shape of each individual mold is a bit less space-efficient than the round FOSOE molds if you’re just trying to tuck one into a tight spot.

My Expert Experience
* Design for Simplicity: Everything about this DAPOWER mold is engineered to prevent common user errors. The fill line is the standout feature—it’s a small detail that makes a huge difference in getting a perfect sphere every time. This is the exact mold I would give to a friend who is completely new to craft ice.
* Durability and Safety: The mold is made from high-quality materials and feels very robust. I have full confidence that it will hold up to repeated use and dishwasher cycles without degrading or cracking.
* Ice Quality and Release: The spheres came out consistently well-shaped and uniform. While the release isn’t quite as squeeze-and-go as the soft-bottom FOSOE model, the simple warm-water trick works perfectly and takes only a few seconds. For the trade-off of a leak-proof and ultra-stable design, it’s a minor inconvenience.

My analysis shows a clear divide. Your primary choice is between a system that produces perfectly clear ice (like the UNIGUL and ecozy machines) and a standard mold that gives you large, slow-melting spheres at a budget-friendly price (like the FOSOE and DAPOWER molds).

When comparing molds vs. machines, the UNIGUL insulated mold offers the best of both worlds: it produces stunningly clear ice without the high cost or large footprint of an automatic machine. The ecozy machines are a premium choice for those who value the ultimate convenience, speed, and on-demand production above all else.

If aesthetic presentation and flavor purity are your top priorities, I strongly recommend choosing an option that makes clear ice. If you’re simply looking to cool your drink with less dilution and are happy with standard cloudy ice, the value offered by the silicone and plastic molds is impossible to beat.

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

Choosing the right ice ball maker comes down to balancing four key factors: the type of ice you want, your budget, how much effort you’re willing to put in, and how much space you have. Here’s what I recommend you consider based on my testing.

• Ice Clarity (Directional vs. Standard Freezing): This is the single most important differentiator. If you want that glass-like, transparent ice you see in high-end bars, you must choose a system that uses directional freezing. This can be an automatic machine like the ecozy models or an insulated mold system like my top pick, the UNIGUL. Standard molds like the FOSOE and DAPOWER freeze from all sides at once, which traps air and impurities, resulting in cloudy ice. For whiskey aficionados who prioritize aesthetics and purity, clear ice is the ultimate goal.
• Type: Automatic Machine vs. Insulated Mold vs. Standard Mold:
  • Automatic Machines: This is the most expensive, premium option. They are best for those who want clear ice on-demand, very quickly, and in high quantities. They require dedicated counter space but offer unparalleled convenience.
  • Insulated Molds: This is the mid-range sweet spot for quality. They produce clear ice just like a machine but require a 24-hour freeze time and take up more freezer space than standard molds. This is the best option for achieving top-tier quality on a reasonable budget.
  • Standard Molds: This is the most budget-friendly and compact option. They are incredibly simple to use but will only ever produce cloudy ice. They’re best for beginners or anyone on a tight budget who still wants the benefit of a slow-melting shape.
• Ice Ball Size: Most whiskey ice ball makers produce spheres between 2.4 and 2.5 inches in diameter. I found this size to be ideal, as it fits perfectly in a standard rocks glass and has a very large thermal mass, which is why it melts so slowly. Smaller spheres, while still effective, will melt noticeably faster.
• Material & Safety: Always look for products made from 100% food-grade, BPA-free materials. For molds, silicone is an excellent material because its flexibility makes releasing the frozen ice much easier. Components like stainless steel, as seen in the UNIGUL, add a great deal of durability and a premium feel, ensuring no odors are transferred to the ice.
• Ease of Use & Release: A good mold should be easy to fill without spilling and even easier to open without cracking the ice. Look for thoughtful design features like fill lines, funnels, and flexible materials. For machines, prioritize simple user interfaces and features like self-cleaning cycles.
• Capacity & Speed: Ask yourself: how many ice balls do you need, and how fast? If you’re only making a drink for yourself each night, a set of 2-4 molds that you use in rotation is plenty. If you frequently host parties, a high capacity ice maker like the ecozy Grande is a worthy investment that eliminates any mid-party ice-related stress.

FAQs About Ice Ball Makers

What makes ice clear?

Clear ice is made using a process called directional freezing. By insulating the water on all sides except for one (usually the top), the water is forced to freeze very slowly in a single direction. This process systematically pushes dissolved air bubbles and impurities away from the freezing front, concentrating them in the last part of the water to freeze, which is then discarded. This leaves you with a crystal clear, dense piece of ice.

Do ice balls really melt slower than cubes?

Yes, they absolutely do, and it’s due to simple geometry. A sphere has the lowest surface area to volume ratio of any shape. This means that for the same amount of ice (volume), a sphere exposes less of its surface to the warmer liquid around it. Less surface area contact means a slower transfer of heat, which results in a slower melting rate and less dilution of your drink.

What is the best size ice ball for whiskey?

The ideal size for a whiskey ice ball is typically between 2.4 and 2.5 inches. This size is considered the sweet spot because it’s large enough to melt very slowly but still fits comfortably in a standard rocks or Old Fashioned glass without getting in the way as you drink.

How do you get ice balls out of molds without breaking them?

The key is to let the mold temper for a minute or two at room temperature after taking it out of the freezer. You can also run the outside of the mold under warm (not hot) water for 15-20 seconds. This slightly melts the very outermost layer of the ice, allowing the sphere to be released easily without cracking from pressure or thermal shock.

Are silicone ice ball makers safe?

Yes, as long as you purchase from a reputable brand that advertises “100% food-grade silicone” and “BPA-free.” High-quality, non-toxic silicone is an inert material that does not impart any taste, odor, or chemicals into the ice. To be safe, I always recommend washing any new mold with warm, soapy water before its first use.

Why do my ice balls crack?

Ice balls can crack due to thermal shock. This happens when a very cold ice sphere (at freezer temperature, around 0°F) is suddenly dropped into a much warmer liquid (room temperature, around 70°F). To prevent this, you can temper the ice ball by letting it sit on the counter for a minute before putting it in your glass, allowing its surface temperature to rise slightly.

Can I use tap water to make clear ice?

You can, but for the very best results, I recommend using filtered or even distilled water. Tap water contains a higher level of dissolved minerals and impurities. Even a great directional freezing system has to work harder to push these out. Using purer water from the start gives you a better chance at achieving perfectly flawless, glass-like ice.

What’s the difference between an ice ball mold and a machine?

A mold is a passive system, while a machine is an active one. You fill a mold with water and place it in your own freezer for 12-24 hours to freeze. An automatic machine is a countertop appliance with its own refrigeration unit that actively freezes the water and harvests the ice for you, often in under an hour, without ever needing your freezer.

How should I clean my ice ball molds?

Most modern silicone and plastic ice ball molds are top-rack dishwasher safe, which is the easiest method. Alternatively, you can wash them by hand with warm, soapy water. For automatic machines, always follow the manufacturer’s instructions, which usually involve running a built-in self-cleaning cycle, sometimes with a bit of vinegar or a specialized cleaning solution.

Are ice ball makers worth it?

For anyone who enjoys sipping high-quality spirits like whiskey, bourbon, or scotch, I believe they are absolutely worth it. The reduced dilution provided by a large ice sphere allows you to enjoy your drink’s intended flavor profile for a much longer period. Even a budget-friendly mold can significantly elevate your daily drinking experience, making it feel more special and deliberate.
