Tcamp 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

The Tcamp Ice Cube Tray for Stanley Cup tumblers is a good concept, but it has some flaws. The silicone material makes it easy to pop out the ice cubes, and the included lid and bin are convenient for storing extra ice. The size of the cubes fits perfectly in my 30 oz tumbler, which is great for drinks like iced coffee or cocktails. However, filling the tray can be a bit tricky since the lid doesn’t seal tightly, leading to spills if you’re not careful. Also, the silicone feels a bit thinner than expected, so I’m unsure about its long-term durability. Overall, it’s functional and gets the job done, but it could be better with a more secure lid and sturdier construction.

The Tcamp Tumbler Ice Mold is a fantastic way to keep my drinks cold for hours. The hollow cylinder shape fits perfectly in my 30–40 oz tumbler cups, and the silicone molds are super easy to use and clean. I love that it comes with lids and a bin for the freezer—makes storage neat and hassle-free. It’s a simple but clever solution that works great and adds a fun touch to my beverages. Highly recommend for anyone who wants long-lasting ice without the mess!

Didn’t know I needed it until I got it now. I can’t live without it. Perfect for the 40 ounce tumblers.

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

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.
