Ice Mold for 30-40 oz Tumbler Cup, Silicone Ice Cube Tray With Lid and Bin for Freezer, Ice Ring Ice Maker for Chilling Cocktails, Whiskey, Drinks, Coffee, Easy Fill and Release (Black)

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.

Works like a charm. Fits perfect, can use 2 at a time in the 30oz mug. The carrier case doesn't stay close. No biggie, you just keep it on the shelf anyway

Great ice silicone for cups and a good price. The ice holds up for about 6 to 7 hours for me but it’s really based on what type of cup you have. I like that it came with a container so water won’t get everywhere in the freezer. My only issue is with the removal, it’s easy to remove but it’s gonna hurt your hands because of how cold it is. You might need to break off some ice at the bottom and top to get it out. Just a heads up in case you need to do this before going somewhere, it may take more than 5 minutes if you’re very sensitive to cold things.

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

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.

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.

Simple and easy to use, design makes it easy to remove ice and refill. Material used is quite flexible. The 3 modules are enough to chill a 40oz Stanley cup. I think the ice moulds could’ve been thicker so it could last longer against the liquids in the cup

Got the 40oz for the Stanley Quencher H2.0 and i did not expect to like it this much. After putting in the three ring cubes i still have ice 2 days later. The rings eventually fuse together which is perfect and keep the drink cold. Eventually on day 3 it melts to the smallest ring and I remove the leftover small ring, replace with 3 fresh rings then insert the left-over small into the big ring. I have no residue problems. I use bottled water to make my ice so those complaining about residue from the ice may want to use a different water source.

Ice tray works great, the ice lasted all day in my cup.

Love this i use it everyday

It’s nice the ice keeps my Stanley cold for at least a day but the ice is kinda hard to get out of the molds

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.
