Product review (1 stars): not reliable
Bought the units after reading the reviews. Worked well for about 1 month with steamy hot and chilly cold water as other reviewers said. The unit starts to leak from top down the white tube and soaked all my kitchen floor. I called the 1800 number on the sticker inside the door. They said it was a serious problem at should be returned.  I just sent the return request on Amazon hopefully the seller takes it back. I may give it another try if he sends me a new replacement.
