Ice Cube Tray for Tumbler Cup 20-40 Oz, 3 Sizes Silicone Cylinder Ice Mold with Lid for Freezer, Easy Fill and Release Ice Cube Maker for Drinks, Coffee, Whiskey, Cocktail (Black)

Super happy with it after the first use ! Ice lasted all day at work and Into the evening at home. I washed it first before using, and let it sit for a few minutes after I took out of freezer. Zero issue getting cubes out. Definitely easy when you push the middle in slightly and then pop from bottom. Yes you will get a white residue in cup but that happens with any type of ice in a stainless cup.

Works very nice with Cirkul's tumbler. I didn't give 5 stars because the cubes don't come out easily. Excellent way to keep your water cold in any large tumbler.

The item works perfectly. Great fit in the cups. Only “negative” is they are thick &, therefore, take up a space that decreases the amount of liquid. I generally only use the small ice block instead of 2 or all 3 ice blocks for that reason. Great product. With very little downside, if any.

Using this left an insane amount of silicone residue on the sides of my cup. I could actually feel and taste the silicone particles in the water. Refreshing microplastics!

I really like this ice mold! It has a cute flower pattern in the middle and really keeps my drink cold for a long time. The only downside is that it has a silicone cover so you have to be careful not to overfill it. Other than that, no complaints! Highly recommend!

Size of cubes is wonderful. Low rating because: 1) very hard to get ice out of molds; and 2) mold leaves residue all over ice which then creates residue in drinkware and throughout beverage. Don't notice any off-taste because of the residue; however, the film standing on top of beverage and all over inside of drinkware is very off-putting. Have tried washing the molds but residue still returns. I won't be using these to make ice for drinks again; may use in future to make large ice for ice chest or something similar, but not for direct contact with food or drink. Very disappointing.

This mold come in handy because the ice last so long in my cup. Sometimes I freeze oth things in it to add to my cup of different flavor.

I enjoy. At times a little bit hard to get out but good
