"The best I have used easy to open loads of room in the back for extra connectors easy to connect safety covers for over screws .Horse proof as fitted in stables .And the price just fantastic at £5.99p WOW"
"Bought two online and when installed jammed in on position. Made sure back box wasn't warped etc and it jammed in on position still. If you dismantle and smack it it eventually works again only to jam again. Eventually gave up and took them to my local branch who swopped them no problems. New ones do the same. I've given up with them. Just avoid these and the hassle they bring!"
