Have been waiting weeks for a fix for my water heater that is not working. They tried to reach me once and then referred to the hotline. With this I have now tried 3 times over 30 minutes each time, without success. Customer service is an absolute disaster and what good is a x-year guarantee if nobody cares. Product already defective upon delivery. Absolutely NOT recommended to buy.
