Where to start?
No included screws or wall plugs for the install.
The lower screw location is offset from centre by 10mm, in what looks like some sort of after-thought, as the mains junction box obscures the centre/lower stand-off, leaving noway to install at that location. They've drilled the left/lower stand-off with an additional screw location (mentioned above) with no rear stand-off behind making it susceptible to cracking the housing.
Its no wonder they recommend installing in a dry location as there is very little thought gone in to keeping water/mosture out, particularly with a hard wire install.
The stand-offs are 4mm long, so If you're planning on upgrading from an old controller to this model and want to run your 8core retic cable behind the controller, be prepared to rebate your mounting surface or persist with a controller that is not flush and/or risk crushing the cable.
There is no ground terminal for the mains earth cable.
I could go on, but I've wasted enough time on this garbage.
