Tcamp Ice Cube Tray for 30 oz Tumbler Cup Ice Mold, 3 Pcs Silicone Hollow Cylinder Ice Tray with Lid and Bin for Freezer, Ice Drink, Juice, Whiskey, Cocktail (Pink)

Works well in my Hydroflask cup. Last a long time keeping the liquids cool. A bit difficult to remove the ice rings from the mold. Does do away with the issue of a straw getting obstructed by a clump of ice cubes.

I’m really impressed with this ice tumbler mold! It fits my tumblers perfectly, and the ice cubes come out easily with no hassle. I love how simple it is to remove the ice—just a little twist, and it pops right out, no need to fight with it. Plus, it’s super easy to refill, so I can keep making fresh ice without a ton of effort. The mold is sturdy and doesn’t leak, and the ice cubes are the perfect size for my tumblers. It’s definitely made my drink game stronger! Highly recommend this if you want a convenient and efficient way to make ice for your tumblers.

Works great a little challenging getting the cylinders out and the top doesn't fit securely

The ice tray works good, like the 3 size cubes. Easy to use

This has been the best thing I’ve bought to date. I always have my water with me and I got to have ice in it. And thanks to this thing my ice stays for about 2 days. I love it.
