I love my bottom loading water cooler. A few weeks ago my ozone button failed. I contacted support. Sean R. responded very quickly with some ideas to try,. We worked together to try and resolve the problem through emails with detailed instructions. After nothing worked I am receiving a new cooler and decommissioning the old one. What a wonderful company to work with and especially Sean who walked me through the problem solving process. I would give Sean R. and this company 5 stars....happy to be hydrating again....Wendy S
