Silicone Ice Cube Trays Large for Whisky, Collins Ice Cube Mold Tray Also Used for Butter Mold, 2 Count

Great product to make large ice cubes. All you need is one of these in your thermos and it will keep it cold.

Keeps beverages cold for a long time. Fits in my water bottle perfect

Look at the product dimensions, this is much longer than a regular ice cube and much thicker. It is silicone all around so it is wobbly when filled with water. I am using a plastic tray underneath it to give it balance. I like the product and the product description is accurate. I am a bit cautious about durability. Every time I remove an ice cube I am concerned it will rip. 2 year update, two of the eight slots have rips. I think this could have been avoided if I waited to remove the ice. Removing the ice right away requires some force, letting it sit and separate a bit from the product is probably the best move. Ordering another set because I really want 8 large ice blocks at a time.

Super easy to remove ice from the tray, but super hard to put back in the freezer whilst filled with water. I'm enjoying the large size ice - just a pain to put back in the freezer since our ice trays go on the top rack (given I am a fun-sized person). Anyhow, I will keep using it despite the spills and frustration it gives me each time (can't believe I'm complaining about such a thing, but hey, you're getting an honest review here. Also, if you're a tall person, you might not have an issue like I have.

Cheap and good size. I carry a massive water jug and I really like ice in my water. These "cubes" are larger than the normal tray ice I've been using. So they last longer and keep it cold for longer. The only real downside to them is once filled with water they bend so sometimes if I'm not careful water spills out. But beyond that they work great. They are also large but their form factor is small enough to fit into my water bottle jug opening with ease.

As mentioned by other reviewers, the product is much much too flimsy. It's extremely unwieldy to try to fill and store the ice, and because the silicone is too flimsy, the ice deforms and in general the product is not sturdy enough to make ice this way.

Makes great ice cubes for thermal water bottles. I haven't used them for butter but I'm sure they'd be fine

We ordered these to get longer bigger ice cubes for tall drink cups and/or our big yeti type cups. They work very well. They are easy to use...just fill with water and the cubes just pop out easily cause it's easy to bend the silicone material and the ice cube doesn't break. Great quality material as well. It comes with two of them so you have a set. We really love them and will definitely be getting a lot of use out of these for the summer! Def recommend this company's products if you are looking for a good quality non expensive item.
