Have Extra waiting to meet with the review to a practical statement. The clock is now almost 2 years of ownership. Processing and movement are very good. The daily, automatic time adjustment, which takes place at 03:00 at night always runs, perfectly and second. The light sensor reacts very fast and very accurate, the lighting is discreet but visible in this mode. In stage continuous lighting luminosity is strong, but also disturbing. Unfortunately, more of a gadget with the light, because it is readable in full darkness with only a smaller distance. The volume of the Clock, I feel as a whole barely noticeable, the clock use in the bedroom. Finally, the battery power, which is absolutely great. With a discount battery and mode on the sensor, a battery for use the clock keeps time despite the daily matching and night lighting nearly 18 months. So overall up to the small point of criticism of readability at night a super quality.
