The clock is really not schlechet. Well finished, the strap is not quite as stable as hoped. It is made of soft silicone. And you can supposedly do not change when it is broken. As others described the display flickers slightly, you can hardly see with me however. One major drawback I find that the clock no volume keys is to make louder and softer. For example, if you can look at a Youtube video to regulate any volume, you have to set them beforehand (or what someone has found how to do it, then please to answer). For other programs, it is unfortunately the same way. Some apps a volume software is already integrated, since it goes well. WLAN, GPRS and Co work for me really well with no dropouts. The display can be operated very well, I did not think, even though it's so small you meet relatively well all keys. The battery is keeping about 1 day with play around the CLOCK. Bin with the clock satisfied and they can recommend. We'll see what the future holds so (if the bracelet is keeping :-))
