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 (Green)

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.

Cute color, the holder is good quality, the ice try its self is good also. Only issue is getting the ice cubes out due to the cold but that's because its ice! Lol recommendation don't fill them to the top of the center allow some room for movement. Would recommend! I have a 30 oz stanley

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

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.

Got this for my mom who loves her cup to have more ice than water. The ice fits great into the cup, but it is hard to get them out of the mold.
