These work great! They are flexible, they have just the right thickness to make sure it is sturdy enough to move to freezer, the size was perfect as we used them for the dog dishes this summer, use worked well, durability has maintained, and for use the ice quality was more than proficient. Would be perfect for plunge tubs.

We are currently using them for our chickens in Arizona, and it is doing an excellent job, Keeping them alive and cool. The molds are easy to use if they are Annie, uneven surface. They do leak. Otherwise they are durable Is it a remove, and it was a good cost for it.

Durable silicone. Great size. Great price. I use these block in ice baths, perfect size

We used these ice molds for our ice baths and they works amazing. Very durable and the capacity was great. Freeze time was about 24 hours.

Makes block ice rather effectively. It’s a little squishy, so that walk from the sink to the freezer may well leave a few splashes, but no matter, they are sufficient to the task. I have a chest freezer on a boat where we try to manage our energy needs. I make and fill the empty voids with block ice when we have shore power. When we need to be on battery power, with excess room filled with ice can go days without needing to turn on its power. When access to shore power is restored, I can just cool the unit down and it’s ready for another few days without even using any power.

Work great and hold a ton of water. Ice peels right out. Only hard part is finding somewhere in the freezer to sit them because they are flimsy (obviously) so they will spill easily if you aren't careful

These definitely will freeze water fine, the difficult part is trying to get them into the freezer. They're so floppy that it's too easy to spill the water, and you can't stack them in the freezer so you need a separate place for each one. It was easier for us to put them on a cookie sheet and then freeze it.

These are great blocks of ice to use for my ice bath.
