In principle, the clock is not bad. I use them in the emergency service keeps them there very well looks good and the light function is also very cool! Unfortunately, my clock is a problem that it will stop every now and again. Then only the screw helps to adjust time pull out and push in again (and, of course, new clock set). Then she runs again. I have the screw now secured with a strip adhesive tape, ... now it goes. But am still disappointed because the clock is so cool and you have saved on the processing ... :(.
