Having stayed a few years ago for a "light alarm" and sought only cumbersome, unsightly and expensive equipment also have found for you also have an extra needed a bedside lamp, I am now stumbled on this Wake-up Light. Not without a certain amount of skepticism, I still decided to do it and am absolutely convinced (like my wife). With it I can do it but actually, now get up every morning at 6 to run an hour before work. In order not to screw the expectations too high: While running, he unfortunately does not help.
