Rated 4 out of 5 by from Little white gem waned a cheap yet study surface mounted box for a fused outlet switch and this fits the bill perfect. very cost effective (cheap) and yet can't fault the quality. Its a plastic box at the end of the day. No sharp edges smooth to touch and more than enough knock outs etc. Will buy again.
