Easily the most poorly designed household product I have ever purchases....and I bought two! On one the transformer failed. Really, how often do transformers fails? On the other the power cord was bad. To their credit Koehler sent replacement parts. Then the trouble started. I had to take the cover plates off. The screws are completely inaccessible. I finally got the screws out and the parts replaced. Just turned the power box upside down. No way it was going back on as designed. Bottom line: looks cool, not worth it. Avoid it at all costs.
