Bought two cheaper because the unit. This product fully meets my expectations. Easy programming with many possibilities: totally 10 different programs can: either with programming by day by day, one day out of two, period of 3 consecutive days (read my sea / Thu Fri Sat) or alternative (read Thu Fri / Sat my game, on weekdays (including or not on Saturday) or just for the weekend, a full week to finish or randomly to simulate a presence. Of course we can put in automatic or manual mode. FOR INFO, if it takes 14 hours in the spare battery charging, in case of power failure it takes more than 21 days without fail, I tested it by unplugging it (after loading) I stopped after 22 days (it was getting long) so that the programmer does not yet show any weakness in the display and is triggered at each scheduled program.
