Soft and pliable silicone. Nice sized ice cube for standard size 11 oz. whiskey glass. What more could I ask for. I would recommend.

Easy to use and clean. Had a weird smell on arrival but washed and it went away. No weird taste on liquids frozen. Used for juice and fruit cubes for mimosas. Cute idea!

Love the large ice cubes! Easy to fill and the pop out easily. Like only having to put one cube in my drink. Cubes also last quite awhile.

Brilliant. One large cube vs a bunch of smaller ones.... it keeps the drink consistently cold. And my kitties love watching one melt in their water fountain. Buying more as gifts! Oh--you can also make fancy cubes with these for mocktails... put a sprig of rosemary, rose petals... whatever. I rarely write reviews so I must be very happy.

These silicone ice trays are great. I like the big ice, they nest well together. Just don’t overfill them prior to stacking.

The silicon molds are really easy to use and get ice cubes out. It is not like the older plastic trays where half the time they are stuck or you only can pop out a piece of the ice cube. With these you can easily slide them out by just pulling the molds down and pushing from the bottom, they just pop out. The ice cube size of these trays are meant more for cocktails at about 2inches square, so think of them as perfect size for a rocks glass. They do have a size up where if you were looking at only massive ice cube in a glass you could use, but these generally you'll put 1-2 on a rocks glass, or a tall glass probably 3-4.

These are really cool ice trays. They are made of silicone so they are not rigid like the trays we are all used to, they are flexible and squishy. However, as many are probably wondering, that does mot make them difficult to fill. They actually require no more support on your way back to the freezer from the sink than your old fashioned ice trays do. They make large cubes which i love because i need to get ice less often. They have a capacity of 6 cubes per tray and you get 2 trays with your order here.In my opinion they freeze even faster than the old trays even though they are bigger cubes, maybe because of the material, not sure. But i worried it would take forever and that's definitely not the case. I can fill them several times throughout the day if i need to. I typically don't have to because the cubes last so long, but can if needed. Lastly they are so easy to empty even for little hands . You just pop them out from behind. I pop them out one at a time and it takes about 3 seconds. Plus no left behind ice stuck on the tray that has to melt before you can refill it. A full cube pops out, you refill, and in a couple hours they are ready again. My mom was over the other night for dinner and I ended up ordering my second set of these because she saw them and loved them too, so fan favorite in our house.

We really enjoy the large ice cubes that we get with these trays. The cubes aren't quite a full 2" by 2", but they're large enough to fit comfortably in a tumbler. They are made from sturdy but extremely flexible silicone with a beveled edge on the bottom that makes the trays stack nicely and also facilities removing the cubes.To make it easy to remove the cubes, don't fill the trays all the way to the top. Stop a little less than 1/4" from the top, leaving space for stacking the trays in the freezer. Then to remove the cubes, place the trees face down on a clean, flat surface (I use a towel on the kitchen counter) and push them from the bottom to loosen the ice. The material is very flexible, so that you can use your fingers on the rim of the tray and your thumb on the bottom to push out the cubes. Be careful; the large cubes and the silicone will remain cold enough to cause frostbite if you handle them for too long with your bare fingers.You can get the individual cells for the cubes to come out the same by over-filling the whole tray a little at the start, and then tilting the tray just enough to spill water uniformly from all six cells. There seems to be a bit of engineering here; the material is thick enough to keep the filled trays pretty flat as you transport them back to the freeze, but flexible enough that it's easy to push out the cubes.There are several similar products on Amazon. These have the brand name "Kitch." cast into the side. As best I can tell from the photos and product descriptions, all these silicone trays are functionally identical; but I've only ever experienced these Kitch brand trays. The silicone is the same material used for simulating skin and other body parts, and that also appears as a liquid or in gel form in prosthetic inserts. (Don't confuse it with silicon, which is a silver-gray metal. Silicone is a polymer that has the silicon atom in a chain with oxygen and hydrogen atoms.) It can take a very wide temperature range, so these ought to be able to shrug off dishwasher temperatures where other synthetic rubbers might deform or even come apart.Silicone material is rather pricey, which probably accounts for the prices you see on this type of ice cube trays. It's darn well worth the cost for the performance we've experienced. I've seen no degradation even after a few dozen cycles through the freezer and being stretched in odd ways as I push out the cubes.I've seen some notes about a "white residue" in reviews of similar products on Amazon. I suspect that this comes from 3 possible causes; in order of likelihood: (1) fiction, (2) impurities in the tap water that would be solved by adding a charcoal filter to the tap, or (3) ice forming as atmospheric moisture condenses on the cold silicone surface. We use filters on our kitchen and bar faucets so there's no chemical residue, but I do usually see frost forming.
