Detailed reviews
We think the Tovolo set makes the most sense for someone who wants a couple of big spheres for whiskey without giving up shelf space. Each mold has a wide fill opening, a water fill line for consistent size, and a lid designed to stay leak-proof, and the molds stack, which is the feature we would weigh most heavily for a small or shared freezer. Each mold is sized for a generously large sphere that suits a rocks glass.
Owners report that the spheres come out neatly formed and that the extra size noticeably slows how fast a drink dilutes. Filling a little under the line matters, since a full mold can freeze into an oblong shape, and the ice will not be fully clear. A common complaint is that the ice sticks hard in the mold; owners also report that the ice slips out easily in other cases, and that the molds turn brittle and crack. As a pair it will not feed a party, but for a household pouring one or two drinks an evening it covers the job.
Pros
- Stackable molds with leak-proof lids
- Water fill line keeps size consistent
- Wide opening makes filling easy
Cons
- Ice can stick hard in the mold
- Overfilling gives oblong spheres
- Molds can turn brittle and crack
Key features (4)
- Pair of sphere molds with stackable, leak-proof lids
- Water fill line for consistent sphere size
- Wide fill opening that avoids funnels
- Release works best after a short rest at room temperature
The Fosoe set is a four-pack of separate molds, each with a silicone bottom and a clear top that splits in the middle for filling. Because every mold stands on its own, they slot into leftover corners instead of needing a flat shelf, which is where this set pulls ahead of the WIBIMEN 1.9-Inch Ice Cube Molds, whose trays need a level spot. The clear lid lets you see the water level, and the split design makes it easy to drop in mint, lemon or other add-ins before freezing.
Customers praise the size for rocks and whiskey glasses and like that the lids keep water from spilling. Owners report that some molds pop the ice out with a squeeze of the silicone, while a common complaint is that frozen ice can be hard to get out. Overfilling can push the top open, and owners report the ice fracturing on the way out, though the silicone is also described as sturdy.
Pros
- Four standalone molds in one set
- Clear lid shows the water level
- Lids keep water from leaking
Cons
- Releasing frozen ice can be difficult
- Overfilling can push the top open
- Ice sometimes breaks apart when tapped out
Key features (4)
- Set of four separate silicone-bottom sphere molds
- Split design that opens for easy filling and add-ins
- Transparent lid for judging the water level
- Squeeze-the-bottom release with a short rest before unmolding
If you serve a crowd, the WIBIMEN set is built for volume: two rigid trays of six spheres each, 1.9 inches across, filled by pouring in water and closing the lid. That squeezes out the excess, so there are no funnels and no slow trickle through small holes. Twisting the tray releases the whole batch at once, which is much quicker than the Tovolo Craft Ice Sphere Molds Set of 2 when guests are waiting.
Owners report that the ice looks classy and works well in cocktails, and the trays are said to beat softer silicone molds. The limits are on the ice itself: some find the spheres on the small side, and a common complaint is that not every sphere comes out fully round. Owners also mention spheres breaking as they come out, and the freezer shelf needs to be quite flat or water can spill from the side.
Pros
- Two trays of six spheres each
- Pour-in fill, no funnel
- Twist release frees a whole tray
Cons
- Some spheres come out less than round
- Spheres can break during release
- Needs a level freezer shelf to avoid spills
Key features (4)
- Two rigid trays making six 1.9-inch spheres each
- Lid that squeezes out surplus water when closed
- Conical bumps that help the ice break free
- Thicker edges for easier twisting
The Unigul Large Ice Ball Maker Mold gives you 2.5-inch spheres, eight per tray, so two trays yield sixteen in one freezer cycle, and it comes with a container and tongs. That is a lot more big ice than you get from the Fosoe Silicone Ice Ball Molds, and it uses the same pour-in, twist-to-release approach as the WIBIMEN trays but at a larger size. Owners report the larger spheres keep a whiskey drink from watering down as fast, and that the trays hold up well in daily use.
The shape is where this set gets criticism: customers say it does not always produce true circles and that completing a full ball takes care. A common complaint is that the tongs work poorly, the fill line sits high so filling slightly below it works better, and the included box is too small for both full trays of spheres. Owners disagree on release and freezing time, with some finding the ice slips out and the freeze matching their freezer, and others waiting a full day.
Pros
- Sixteen 2.5-inch spheres per cycle
- Container and tongs included
- Owners find it durable day to day
Cons
- Spheres are not always fully round
- Included box too small for both trays
- Water fill line sits slightly high
Key features (4)
- Two trays of eight large spheres each
- Twist-release design with thicker edges
- Included container and tongs for storage and serving
- Pour-in filling without funnels
The Unigul Clear Ice Cube Maker is the one set here designed around clarity rather than just shape. It pairs a stainless steel vacuum-insulated cup with a silicone mold so water freezes from the top down, pushing trapped air and minerals toward the bottom, and it comes with an ice storage box and tongs. Each unit stands upright with a 3.4 × 3.4 × 6 inch footprint, and the slow-melting 2.5-inch sphere suits whisky and cocktails served neat.
Owners praise the ice clarity and the roundness, and say it beats cheap silicone balls. Plan for a long freeze of at least 20 hours; it only makes two spheres per batch, so it is a different proposition from the Unigul Large Ice Ball Maker Mold. Release is the sticking point: owners report spheres that slip out in some cases and are extremely hard to extract in others, which is why the instructions call for a short rest and a gentle wiggle. Owners also disagree on whether it is worth its cost.
Pros
- Directional freezing for clearer spheres
- Insulated steel cup with silicone mold
- Storage box and tongs included
Cons
- Ice can be very hard to release
- Makes only two spheres per batch
- Owners disagree on its value
Key features (4)
- Stainless steel vacuum-insulated cup around a silicone mold
- Two 2.5-inch spheres per batch
- Includes an ice storage box and tongs
- Upright design sized for flexible freezer placement
The Samuelworld set covers two shapes: four 2.5-inch spheres and six 2-inch cubes, with an integrated funnel for filling and silicone covers that seal the spheres. That mix is what separates it from the Clear Ice Cube Maker from Unigul, which commits entirely to one clear sphere. It is the one to pick if you pour both cocktails that want a square cube and sipping drinks that suit a ball.
Customers say the quality is good and that the trays fill without fuss and make well-shaped ice. Durability is where owners differ: some find the large cubes last far longer in a glass, while others say the spheres crack and the hard base gives out after repeated use. Owners also report that the sphere lid sticks hard coming out of the freezer and that the large volume of water needs about a day to freeze solid, so a short rest on the counter helps.
Pros
- Both sphere and cube trays included
- Built-in funnel for mess-free filling
- Large cubes last a long time in drinks
Cons
- Sphere lid sticks after freezing
- Spheres can crack, plastic may break
- Large volumes need a long freeze
Key features (4)
- Four 2.5-inch spheres plus six 2-inch cubes
- Integrated funnel system in the sphere tray
- Silicone sphere cover that seals against leaks
- Food-grade, BPA-free materials that go in the dishwasher
The Rottay set pairs a six-sphere tray of 2-inch balls, closed with a quick-open buckle and a bonus funnel, with a six-cube square tray in silicone. Like the Samuelworld Large Silicone Ice Trays, it gives you both shapes, but its spheres are smaller at 2 inches and it relies on a buckle rather than a stretched silicone cover. Owners like the ice for neat drinks, craft cocktails and Yeti-style cups.
The durability reports are the most cautious on this page. Durability is the main complaint: owners report cracked hard portions, bottoms splitting while frozen, and the silicone on the cube tray ripping. Size draws mixed opinions, with some saying the cubes are smaller than they expected, and owners report that the spheres leak or do not fill fully. The square tray also needs warming under water before the cubes will release, so it asks for some patience.
Pros
- Includes sphere and large square trays
- Quick-open buckle and bonus funnel
- Good for neat drinks and cocktails
Cons
- Owners report cracking and breakage
- Silicone cubes can tear
- Spheres may leak or not fill fully
Key features (4)
- Six-sphere tray with 2-inch balls and quick-open buckle
- Square tray for six large 2-inch cubes
- Bonus funnel for filling the spheres
- Silicone tray safe for freezer, microwave and dishwasher

How to Choose a Round Ice Cube Mold
How big should the sphere be?
Size controls both melt rate and fit. A larger sphere has less surface area for its volume, so it dilutes a drink more slowly, which is why 2.5-inch spheres, like those from the Unigul Clear Ice Cube Maker 2.5 Inch, suit slow sipping. Small spheres chill quickly but melt faster and suit coffee, soda or juice. Check your glass first, since very large balls will not fit a narrow tumbler; the 1.9-inch trays in the WIBIMEN 1.9-Inch Ice Cube Molds are the easier fit for smaller glasses.
Twist-release trays or flexible silicone?
Release style decides how often you will actually reach for the mold. Rigid trays with a twist release empty a whole batch at once and hold their shape when full, while silicone gives under a squeeze to free the ice. A short rest at room temperature before unmolding helps with either type. For batches to serve a crowd, the WIBIMEN 1.9-Inch Ice Cube Molds are the easy call, and the Unigul Large Ice Ball Maker Mold settles it if you want the most large spheres at once.
- Rigid twist trays: fast batches, a stable shape when full
- Silicone molds: flexible, forgiving, often dishwasher friendly
- Individual molds: fit odd gaps, but fewer spheres per freeze
- Combo sets: add cubes, but give up some of the focus on spheres
Will it fit your freezer?
Freezer room is the hidden cost of any mold. Lids and stacking keep filled molds upright and tidy in the freezer, which is why the Tovolo Craft Ice Sphere Molds Set of 2 works well in a crowded freezer. Flat trays need a level surface, since a tilted shelf can send water over the side. For anyone who wants cubes as well as spheres, the best reusable ice cubes are a separate category that does not depend on water filling at all, while a combo like the Samuelworld Large Silicone Ice Trays keeps both shapes in one set.
Is clear ice worth chasing?
Standard molds freeze from every side, so trapped air makes the center cloudy. Directional freezing pushes the air downward and leaves a clearer sphere, which is what the Unigul Clear Ice Cube Maker 2.5 Inch is designed to do. If appearance is not a priority, a regular mold still gives you the slow melt that comes from the round shape.

Frequently asked
How long do round ice molds need to freeze?
Plan on roughly 20 to 24 hours for large spheres to freeze all the way through; a shorter freeze can leave the middle unfrozen. The Unigul Clear Ice Cube Maker 2.5 Inch calls for at least 20 hours, and owners of the Samuelworld Large Silicone Ice Trays found a few hours left the spheres half frozen.
How do I get the ice out without breaking it?
Give the mold a couple of minutes at room temperature, or warm its outside briefly under the tap, so the bond to the ice loosens before you twist or squeeze. Rigid twist trays like the WIBIMEN 1.9-Inch Ice Cube Molds release a whole tray at once, while the Fosoe Silicone Ice Ball Molds suggest squeezing the silicone bottom after a one-minute rest.
Why do spheres last longer in a glass than cubes?
A ball exposes less ice to the liquid than a cube of the same bulk, it warms and melts more gradually. The gain shows most with large balls, so size counts as much as shape when you want to sip slowly. The Unigul Large Ice Ball Maker Mold is our pick if you want the most large spheres in one go.
