"Just refitted my kitchen and fitted all sockets and switches with the LAP Polished Chrome screwless fittings. Look Really good. Switching is very positive, and they look great, but a couple of things to be aware of: -The deeper the back box the better. I used a combination, but would suggest min. 35mm -The switch plate fits squarely and tightly inside the back box, and on some back boxes with extra 'screw tabs' you need to flatten the unused 'screw tabs' -These will emphasise any unevenness in walls around the switch"
