I bought these timers for the second time. Three of them are for one year in operation and function smoothly. Very good is the Ganggenauigigkeit of watches. The times do not diverge, so you do not have to adjust. Helpful is the automatic summer / winter time change, and the astro function, which adapts the switching times of sunrise and sunset. Here there is also the limitation that you must accept: The astro function can not be combined with weekday dependent programming. These must be switched off. The switching time for all weekdays are then set to the same.
