These trays aren't flexable.
These trays are so rigid they won't flex enough to loosen the cubes. I had to bang the tray many times to get less than one third of the ice released. Banging on the trays also cracks the ice, so you get very few perfect shaped cubes. I use purified drinking water, so running them under the faucet to release is out of the question. I let the trays set a few minutes to allow some melting, which I thought might help release them. But most still stuck (due to suction). I ended up picking some cubes out individually, but gave up due to the ridiculousness of it. When I refroze the wet cubes they all melted together turning it into an ice mass, not the small individual shape that I'd hoped for.
