Customer Reviews


Rated 1 out of 5 by 1reviewer.
Rated 1 out of 5 by I bought this unit a year ago and installed it under my kitchen sink with appropriate breaker and wiring. Even with the unit on high setting, it was not enough to heat it properly. It gets luke warm most of the time and the other time it may not even get warm at all. Not a product I would recommend. I am going with a different one with 220 volt instead of 110 volt, I think this is where the problem is. January 27, 2013
