Was pleased with my purchase, but keep the lower level water low, don't over-fill or you will have things stuck to each other. Due to the thinner silicone it does make getting the blocks out relatively tricky, but if you want to have quite a few good sized iceblocks available, but limited space in your freezer, then these are brilliant. I will be back for another one, as they are stackable, and great for the hot summer months where you get through lots.
