Product review (1 stars): Do Not buy!
Internal fan turns on for 8 seconds and off for 8 seconds. It will drive you INSANE!!  I called company and they said it's actually  supposed to turn off/on every 10 to 12 seconds!  Either way that fan will drive you freaking nuts. I blew $700 bucks on this piece of junk.
Also it takes a lot of electricity. My full size french door refrigerator with water and icemaker takes less than 75 watts, this little thing takes 130!
