Product review (5 stars): Perfect little ice-thimbles
It works very well and makes ice quickly. The only thing I don't like about it is that the ice cubes melt quickly, due to the way they're formed. I have a fridge with no built-in ice maker, so I transfer the ice cubes from this thing to the freezer, and they freeze more thoroughly.

It will make larger cubes if you dump some ice into the water reservoir itself, so it's freezing ice water instead of lukewarm water.
