I would like to say that these are great.  The quality is definitely there and the lids are great to stack them and not worry about tilting them and having them spill.  The little door to open and fill the ice cube tray is a nice idea but not functional enough to use reliably.  If you fill it from there you can not see the evenness of the water in the tray, you can also possibly fill it to much.  If you flip the ice cube tray over it will leak out of the door.  The other thing is that they are over priced for what they are.
