"I bought one having read the reviews and have installed it. Contrary to some reviews it definitely fits a 47 mm deep box. The only point is to know if the wall in which you fit it is cavity or solid. (different type of boxes for each wall) However Screwfix supply both sorts so I bought one of each as I wasn't sure of the wall. I have tried it charging a shaver and even with my ear to the unit, I can't hear any hum or vibration. Seems good all round."
"This shaver socket is very energy efficient, but as a previous reviewer mentioned mine does not fit into the existing box either, the transformer is slightly too high. Such a shame, hope Crabtree can rectify this small issue."
"the socket has very good features and an excellent price. How ever it will not fit into a 47mm surface mounting box (the deepest Crabtree one tha Screwfix stocks). I had to send the socket back and have gone for a cheaper vesion that will fit into the standard box."
"The shaver socket is excellent but you need a 49mm surface mounted box (Crabtree part 9053) to fit it. I tried various other boxes but they were all too small. Screwfix does not stock this box or if they do I could not find it!!!!!"
