Great tray. Works well with a wide mouth water bottle. Will NOT work on a regular 16.9 “Poland Springs” water bottle.

Looked for long ice molds for Nalgene and Hydroflask type bottles, and these work. However, they are smaller than expected (thinner), although the description on size is listed accurately. It takes 4-5 of these to realistically put in a water bottle and then you're out of ice. Glad it comes with 2 trays to help keep up with demand, but they're just ok. 1.5-2' wide x 6' would be more ideal I think for just about anyone. The silicone lids that go on top are a bit tricky to seal down in the corners and don't really stay on that well. Removing ice requires you 'snap' the molds between each cavity and then the ice is susceptible to breaking. Run water over the tray helps loosen the ice for removal. I'll keep these for now, but not super satisfied and I'll keep shopping.

I love these freezer trays. I no longer waste food. I put food items like bananas, strawberries, kale, etc in these trays and freeze them to use in smoothies.

The idea is good but the ice usually cracks when I take it out of the tray. Even so it does work well in my water bottle.

I'm so glad I saw reviews on a similar product that said better to buy one w/a lid. This thing is great, perfect size for the 20oz Gatorade bottles I refill with water, and the lid makes this plenty sturdy enough to not spill while moving it into the freezer. AWESOME!

Great item, ice holds up longer than the ice you can buy.

This is fine, it does what it needs to do. I use an 18 oz Thermoflask and can fit 3-4 of these inside. The cubes are a bit difficult to remove from the tray, and sometimes they break in half. These are stackable and don't take up a lot of space in the fridge. It's good they come with lids, otherwise the water would be spilling all over the place. They are probably a little overpriced for what they are.

This is so much better than a quart sized freezer bags! After the food is frozen, you just pop it out of the tub and wrap up the bricks, which are much easier to stack in the freezer. The two cup portions are easier to use, and easily fit in a bowl for defrosting. These are sturdy, colorful, easy to clean, easy to stack, and the lids fit well.

So I loved my new water bottle with a straw but....ugh, trying to fit it in with ice cubes was a struggle--either trying to jam the straw in a bed of ice or not having as much ice as I would like. I tried ice cube 'rings' that were designed for specific brand water bottles but they did not fit in my water bottle. So I took a chance on these long ice stick molds. PERFECT! Very easy to remove the ice--just push and peel. No problem moving them from filling to the freezer--fill, put on the lid (no spilling) and they are quite sturdy enough to move filled with water, even with only one hand. The straw fits easily between the sticks of ice. I highly recommend these for water bottles especially bottles that have a straw insert.

I love having ice in my water. Ice sticks are more convenient to use in my Yeti and Stanley water bottles than small ice cubes. I was looking for silicone trays, rather than plastic. It took me a few days to get used to using the soft, flexible material, both to fill the trays and to release the ice sticks. For filling with filtered water under the faucet, I support the tray with my hand underneath, then set the tray on a flat surface to attach the lid. This works well. When ready to use, I set the tray on the counter, remove the lid, and wait for just a few minutes, until the ice sticks to barely begin to soften around the edges. Then, it's easy to twist the tray and press the ice sticks out onto the lid. I'm pleased with the size and shape of these ice sticks and I recommend these silicone ice trays.
