Great Customer Service
I bought this on Ebay a few years ago and recently it stopped working. When I contacted SOTA they offered to cover it under warrantee even though it's been a little over two years since I got it. They also sent me detailed instructions on how to check to see exactly what was wrong with it, and in the process I was able to fix it myself ^_^  An excellent experience! HIghly recommend SOTA water ozonator as well as the company.
