All Super .... Except for: The clock I've returned because the display flickered slightly and the charging indicator not working. This was supposed to show in four steps the charge status. But did not make it. A charging takes about 30-60 minutes, but it keeps unfortunately only 3-5 days. Even with the replacement model that is so. Invite every few days, although the GPS transmitter was not in operation, is annoying. Since this is in the replacement model and so, I assume that, contrary to the description of up to four weeks of operation, a little here was simply exaggerated. I'll second the clock even send back well, although I'm really impressed by the design and its features. The load measurement is super and precisely. While it takes several minutes until the satellite was found, but then everything goes stable. Too Bad ...
