Works as it should, great value for money. Instructions aren’t very detailed but I managed to find a youtube video.

The trick for a simple installation is: 1) Control box goes on door; catch goes on door frame. 2) Attach double sided tape to correct surfaces of control box and catch . 3) Now position catch on door frame and engage control box, so that control box double sided tape is ready for the door. Use fillers to keep control box straight. 4) Close the door. 5) Open door with key and impress control box on door. (Screws can be added to both pieces now but avoid distorting the fitting.) There is a video that shows this method but the example given is when the door fits inside the frame. My door was flush not inside the frame, so did not really apply.
