Kitchen 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.

I have bought 5 different ice trays in the last few months to try and find something that works well in my Fifty/Fifty bottle. First square didn't even fit. Smaller half rounds melt right away and are difficult to remove from tray. I was almost at the end of my rope and happened upon these trays. I was a little nervous about the feedback saying you should fill them already in the freezer but I bought them anyway. They came faster than stated and didn't have a nasty smell out of the package. They just smelled like silicone. I washed them and set one in the freezer and filled it from a water bottle. I sat the next one on top of the first and filled it as well. They froze well with no mishaps so they are stackable. It is a little more difficult to remove because of the shape but very sturdy so I just grabbed the cube and pulled. It came right out. I can fit 3 in my water bottle but need to put them in one at a time. They last a very long time! (24 hours and longer) So nice not to have to add ice multiple times a day. One more chore I can say goodbye to! I highly recommend these for refillable bottles!

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.

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.

The trays look great, but are a bit hard to use. Due to the maliable nature of the material, there is nearly no way to fill them with water and get them to the freezer without spilling the water. They're just to flimsy. Ice cube trays need to be made more rigid, like the old plastic trays everyone had back before refrigerator ice cube dispensers were a thing. These are not that.

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.

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
