However, I would have a suggestion for improvement: To attach the stopper, it is necessary a Inlet on the wall to fix it with a screw / plugs. The stopper itself is then attached to the Inlet with a socket screw - this unfortunately sits very close to the edge / on the wall, so that the Allen key can be always rotated only by a maximum of 180 °, 140 ° realsitisch perhaps, must be removed and re- be used. Quite time consuming when you have to fix meherere stopper. Could this be so designed Inlet that you can turn the Allen permanet for final assembly (Inlet would then be twice as long), that would be ideal.
Still, very good product
