I am very pleased with this machine. After using it a while I can say it definitely works better in cooler temperatures. I have mine in the garage, and if it gets too warm (85+ degrees) it works a little slower. If you want CLEAR ice you got to have clear water. I use RO water and it comes out just fine . I would recommend this ice machine to anyone. It only makes a small amount at a time, but if you keep the tray empty it's almost as fast as the one built into the refrigerator.
