Pretty flimsy and had to work with when full of water. The other thing is when frozen the ice takes a LOT of effort to remove. I've found you need to let them melt a while then push out from the back.

I got these silicone molds to be able to make large ice blocks for a cold plunge. I'm happy with the value for the money, the ice blocks are very large, the quality of the molds is good, and they're very easy to use. The ice does stick inside of them a bit, and so you have to run warm water around the edge when you want the ice blocks to drop out, but they otherwise function very well for their purpose. The only other thing I would mention is that you want to wash them out after you use them, because the impurities of the water tend to stick on the silicone surface, so you need to scrub that gunk off in order to have nice ice cubes or ice blocks for the next round of your bath.

Good molds, I was worried about being able to walk from the sink with them filled but they are sturdy and can handle the walk. They are stiff.. it takes a few tries to get the knack of releasing the ice. They do have stretch marks after 2 months of use but holding up well. The ice stays way better than store bought. Will buy again.

Bought these for our portable ice tub instead of using frozen bottled water. These work perfect. Made of good quality, very easy to store and lasts for a few hours of freeze time.

My husband uses these for his ice bath. The silicon makes it easy to get the ice cubes out
