This timer is working properly and can be operated relatively easily. The 8 ON / OFF programs are probably sufficient for most applications, but you should think carefully about it before you buy what you want to do with it. If you want to turn off any day of the week each at different times twice a bit and again, one would need 14 programs since 16 weekday combinations help only conditionally on. The self-consumption is not quite up to date, but ok with 1.05 W.
