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

It does what it is supposed to and the “cubes” fit perfectly in my 30oz Stanley. Before I purchased this, I was using ice balls but these allow for more liquid since they are hollow. I wouldn’t say they last 24 hours but it still keeps everything cold and the room for more liquid is worth it. My only reason for 4 stars instead of 5 is it’s a bit bulky if you don’t have a lot of freezer room, and a little more difficult to fill and pop the cubes out vs a single ice ball (whiskey ball) mold like I was using before.

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.

I so excited to get this product. But all three do not fit into my stanley. The larger one is to big for the opening. It is a little difficult to get them out of the container.

They are very good and love that they fit my mug!

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.

This ice cube tray for the Stanley tumblers is great! I have been using it everyday for a week so far. It's easy to get the ice out of and the ice lasts all day. I wasn't sure if it would be a good purchase based on some of the reviews but it works great for me and I'm very happy with my purchase.

Love the idea for this just wish the ice lasted longer than it does but you can feeeze fruit into it and that’s great

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.
