Programming is really a no brainer and very cumbersome, as already described in another review; But if this is set once, does that part (for me) permanently outstanding ease and reliability, both in the dead of winter at below -10 ° C and at 35 ° C in summer. So I would 4 stars awarded to 5s, with a tendency - when the Kuststoff used would not rather inferior and would just crumble in the third season now ... The problem is probably the lack of UV and / or thermal stability. Short again come a little harder on the outer "overhang" and already the inner housing part is already broken in two places! That happened last summer, not in cold temperatures, when the plastic is brittle stuff anyway. To avoid having to dispose of the device (no idea OBs the housing parts are replacement) I then bent into shape a metal bracket fits and used as reinforcement. So maybe `s still hold a few years. If the door will not - used on the south side and exposed to the greatest solar radiation, but perhaps in the shade and with no major weather, the plastic is likely to last longer - as in my case!
