Very easy to use, I ordered two batches, for two remotes, one for the living room and one for the room because no ceiling in my apartment. Very simple to install and adjust, can control up to four times a remote control, but also control the same outlet via two remote controls. In place for three months and no worry to date.
Only small problem a small screw on the plug rotating in a vacuum, so I was forced to break a small piece of plastic to open the valve.
