I've gotten myself in spite of the growing NEN recessions on the adventure, but the quality really is absolutely not recommended. I wanted the clock, so I can be reached at work. I'm in a suit on the way and wanted to carry concealed. This is also possible. I have always taken the clock in the evening and have to charge stored. This also works really well. As long as the strap buckle remains in place. The clasp is simply dropped after about 10 days, after which the band came off the pin. The SD card is partially not recognized. I had imagined that it had to do with the Umgebungstemeratur. But can not prove us I. I want to get rid of even something positive. The clock / mobile phone has a long Standbye time. But otherwise, the clock is not to be used. I'll probably still need to test some more quality. How anyone could spend on this program via the 200 and could rate it as "good" is beyond me. I can only advise Stay away from this product.
