TcampIce 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)

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.

Very cool for the larger tumbler. With gray and ice last all day.

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.

Works for 30oz cups, all 3 ice trays fit into cup.

Meh.....Size is good and works for the big stanleys.The quality seems good and durable since it is silicone. I purchased over Black Friday so getting on sale was a plus.MASSIVE CON: I use filtered water, BUT since we have hard water, it makes the ice "foggy"/ "filmy" and actually gives it a gross taste. I have washed with soap and water, just hot water, vinegar... nothing has helped. I would not purchase again... I have to figure out a way to get rid of.IF you don't have hard water... or you don't mind a film... these would work well.

The Tcamp Ice Cube Tray for Stanley Cup is a game changer! The ice cubes fit perfectly in my Stanley, making it so much easier to enjoy an ice-cold drink without struggling with oversized cubes. The tray itself is sturdy yet flexible, making it super easy to pop the ice out. I love how convenient it is—no more fighting with regular trays that don’t fit! If you use a Stanley cup, this is a must-have!

After a few uses getting the pop outs back into place has become easier. I not only use the ice molds for my hydra flask, but also for when I make homemade iced tea or lemonade. The ice helps the cold brew tea faster.

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.
