Review on Efficient 4 X Cubette Mini Ice Cube Trays - Set of 4, White by Saul Rivera

I bought 2 sets of 4 pieces - so 8 shapes. Pros: I love the size of the ice cubes, they are tiny and fit in water bottles, glasses and are very easy to crush in a smoothie blender without leaving any chunks. They stack very well in the freezer. Cons: Oddly enough. My regular sized ice cream bowls freeze in a few hours at most, but I had these mini bowls in the freezer all night and they still weren't frozen in the morning! This has been a problem every time for some reason. Then when they froze, they often stuck together, the tray below stuck to the tray above - HARD! Then the cubes don't come out easily at all. The only way to get them all out is to pour HOT water over the top and bottom and then twist them into the ice cube basket. And sometimes, even then, I couldn't get them all out. Sometimes when they landed in the ice cube basket they would stick together in big chunks that I couldn't break up, so my goal is to have tiny ice cubes when they turn into one big lump. To be honest I've finally decided they're more trouble than they're worth and will give them away if someone I know wants them.
