Chillz Ice Ball Maker - 2 Black Flexible Silicone Ice Trays - Mold 8 X 4.5cm Round Ice Ball Spheres (2 Pack)

Especially if you ignore the instructions. LOL I've been using other ice ball trays and have had problems with both of them. The full silicone with 6 small balls leaks like a sieve and I've repurposed a storage box (shoebox sized) to keep the leaked water from freezing it to the bottom of the freezer. That one takes a second fill to make full ice balls, which is annoying. The 4 large balls tray is only half silicone, with a hard plastic base. It doesn't leak, but getting the top loose and the balls out is extremely difficult at times, since the silicone is flush with the rim on the base. I've had to hold it in front of my heater for minutes to loosen it enough to pry open.So I have the hard surface (storage box) to place them in and I just assemble them, place them in the box, and fill them directly from the sink. Any runoff is caught by the deep sides and they are mercifully easy to pop open. Haven't had to refill for a 2nd run at all, and I'm very pleased with their performance.

These have worked great. They seem to melt slower then regular rectangular and half-oval icecubes, I use these in my soylent thermos to keep it ice cold for a couple days and it looks cool with a screwdriver or just straight whiskey.I think they would look less cloudy if I used my own water filter and was more careful in opening them up. Since they never close 100% there is always a rim joining the balls together. I usually break them into pieces and drop them in hot water, this melts the rim off and leaves me with the balls which are never perfect but are really close, this is the fastest way I found to make them.To make perfect balls I think you would need to use filtered water. After freezing for 8 hours or so submerge the mold in lukewarm water until you can easily release the mold. After gently releasing the balls either as individual balls of the connected block drop them in the lukewarm water until all the edges are melted off. I think by slowly heating them and releasing them your less likely to cause them to crack on the inside.

I love ice balls for our drinks. These molds are nice that they do, I feed, make ice balls. My only negative is that both sides are silicone and unless you have a flat spot in your freezer to place these then you will have issues with spillage. Also, slightly squeezing them, which is sort of inevitable, will ooze water out of the little hole on top as well. Other than having to be extra careful, they get the job done and make a nice ice ball that is easy to remove from the mold.

Got a set of these for my husband 3-4 years ago. They finally got a hole or split in them and started leaking. But I think for the price, that’s pretty good. Got him the same set as a replacement and he’s very happy. Says they may have improved them from the original purchase. Love these in cosmopolitans and other fancy drinks. No foul taste or smell. They don’t take up much room in the freezer.

I had read in other reviews that there were issues with the water forming a layer in the center of the mold, between each sphere, and that is the case for my units as well. I tried weighting the top cavity with water to make a tighter seal, but that did not work - I still have to break my ice spheres apart and deal with rough edges on otherwise perfectly round orbs.These also melt just about as fast as any cube of ice, to be honest; if they last any longer, I have not really noticed a difference, and these tend to melt on the portion closest to the surface much much faster than the immersed portion, which creates an uneven shape.The result of this product is definitely fun in a drink, but there are undoubtedly products out there that will produce higher-quality results. The price seems reasonably fair for the quality.

Himself asked for these because summer is coming along and he loves to have a LOT of ice on hand. (He just requested we order four more..) We've been trying several different designs and after trying these I've discovered that these are quite the right size, not just for a glass - but for water bottles (I use Lifefactory and they fit wonderfully). It is a bit of a trick to get them filled properly (he has the hang of it, while I'm still learning. but overall these are a good design and freeze very well. There isn't the problem with them getting stuck either. (we've tried other designs where that has been an issue) These freeze quickly and are clear as pictured. (We do use filtered water)If your looking for a round ice cube (that's an awkward sentence) I recommend getting this one.

The family loves the nice big balls--my wife especially can't stop complementing me on my big balls, even though they can be a little chilly at times. We use these on a daily basis and the silicone makes it easy to use with no risk of breaking. To use, just fill the water up 3/4 of the way in the solid half, then place the holed top on and place in freezer. The water expands as it freezes filling the round section. If you overfill, the ice just protrudes out the top hole, and breaks off when you open to empty the balls. We're not overly concerned about perfect balls of ice, but the large round spheres last a long time when chilling liquids, so a great find.

I chose this product based on price, because I'm sure the little individual capsules that are the same price for only 4 are far superior. These do their job, but don't expect perfect spheres of ice without some finesse. It takes a few tries to get these down; they are entirely made of silicone which makes them extremely flexible and durable, but the flexibility can reduce the quality of the shape as well. You also don't fill the spheres through the little hole in the top, as you would think. The hole is a lot smaller than it looks in the pictures, and the instructions tell you to fill the bottom part 3/4 of the way up, and then press the top part into it until the water flows out of the top hole.
