Likiyol Ice Cube Tray for Stanley Cup, Silicone Ice Cube Tray with Lid and Bin for Freezer, 3 Hollow Large Cylinder Tumbler Ice Cube Mold for Drink, Juice, Cocktail, Whiskey, 20Oz/30Oz/40Oz, Green

Perfect ice fit, great price and super easy to remove and refill for daily ice!

We live in an apartment that does not have an icemaker. So to use are Tumblers we need to make ice weekly. With this ice mold, it saves so much time and the ice last all day. I will be buying more..

Works as it should. The ice is a little difficult to remove sometimes but that’s silicone for ya. Very happy with my purchase and use it in my tumbler every day. Note- it does not fit the Owala

Super convenient and it fits perfectly in both my Stanley and Hydro tumblers. Wish the ice was a little thicker so it lasted a little longer, but overall love it. The ice is easy to get out of the silicone mold and love the container to make storage in freezer convenient.

This is such an awesome idea I hate that I didn’t come up with it myself! Using ice this way in my Stanley keeps the water cold all day, in fact I have ice left at nighttime. It takes a little practice to get the cubes out, you have to pull on them and I think the trick is not to fill each section all the way to the top.

To start, I was excited to get this as I’m a Stanley lover and I wanted to be able to put my straw into my ice filled cup without a fight. I liked the idea of having a hole in the middle for this reason. Now for the problem. After you fill this up with water and freeze it, you then have to man handle the silicone and twist the ice rings themselves in order to release them from the silicone mold. Once you handle the ice and drop it into the your cup according to the number system printed on the silicone, you fill your cup up and go.Another problem: After making sure to use either bottled water or filtered water to fill the ice mold, I kept getting white residue in my water and all over the inside of my tumbler. Disgusting. I proceeded to wash the silicone mold in the dishwasher to make sure there wasn’t a film coming from that and the result was the same. For this, I cannot recommend this product.

Love these ice molds, I bought one for everyone in my office. Ice comes out easily without much pulling and it fits perfectly in my Stanley cup!

Ice mold works fine but the largest (#3) ice does not fit into the RTIC Road Trip 30 oz Tumbler. If you run water over it and it melts down you can fit it in. Didn't have any issues getting the ice out of the molds. Will likely just fill up #1 and #2 for my tumbler and top off with regular ice.
