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)

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.

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

A little difficult to remove the ice from the silicone but otherwise great product

Great value for the money. Forms quality ice perfect for your Stanley and is labeled 1, 2, 3 so you know which to use first, second and third.. common sense isn’t common!!!
