Mechanically, the claws not so great (contrary to advertising messages). If you have the flush-mounted socket set lower by an extension ring, so to get to the locations at which the connection screws are not into it. If you have the time switch but then it, the claws can not really tighten firmly. For other switches, etc. no problem.
For the cable of the solar sensor, there is no recess to deduce it without kinking reasonable from the housing. The solar function itself is not the hit (to the valuation at the sensor more), the adjustable sensitivity is too low in my opinion.
