Previously had a 3.5 KW KDEH (a well-known manufacturer) that Post Warranty (strange) gave up the ghost. The services previously: lukewarm water. Since lines 2,5 were present, had only backup to be replaced (10 euros) and a more powerful machine to be purchased. I am not decided, based on my previous experience, this time for a device for 200 euros and more to acquire and, but opted for this device. The service: very hot water at an affordable price. Whether Again, the warranty period equals the MHD (= maximum expiration date) corresponds, yes I will still learn. In any case: to date = very good.
