Easy to fit although I ended up using a wooden back frame inside the caravan as the one I was fitting it to was old and the walls only made of plastic and polystyrene foam. Contacts are good on the plug and mates well with the socket. Job took me less than 20 mins to do.
Brushes are good. Use them for everything. Cleaning sinks around taps, cleaning grout and also cleaning car wheels!. Last about 6 months with heavy use!
