One thing, the clock is really smart and a real eye-catcher. However, the clock has a huge flaw: It does not work properly !!! This aspect is heavy and therefore I advise against the purchase of the clock. In the first clock which I had received, the battery was empty. Ok I thought gehste the jeweler and you can install a new one. That went without any problems and Amazon even made me pay the costs for these battery replacement. The clock ran out immediately - Unfortunately it has ever time. After two to three days she was approximately three minutes. This phenomenon has unfortunately always repeated and thus remained I had no choice than to exchange the clock. Because I think the clock really nice, I've let a new send. Here the whole thing but even worse, because the second hand dancing completely out of line. Time he moved in the "normal" Rhtythmus, sometimes he moved not to, but then jumped to a record three seconds remain, etc. This circumstance was of course totally unacceptable and I now have two clocks, without any further compensation have to want to be returned! Amazon has once again acted fully customizable in this friendly settlement. Thanks a lot for this !!! So Amazon TOP, clock FLOP!
