Rated 5 out of 5 by from Solid MK stuff Solid, straight forward to fit. Replaced an old one in a grid outlet. Saved the user having to change the whole set up. Well done screwfix for stocking them.

Rated 4 out of 5 by from MK Grid switch dimmer MK grid system makes changing switches simple. The dimmer does what I expected it to - it has a good soft start and decent flicker free lighting control. It's the usual decent MK quality. I'd prefer it to be less bulky on the faceplate as it is quite pronounced compared to the adjacent rocker type switches Reliability score based on expectations!

Rated 5 out of 5 by from dimmer switch Replaced this dimmer with a older one that had started playing up (it was 10 years old and used everyday). loved the fact it only took one minute to replace (got to love the mk grid system). I would buy again even considering the cost.

Rated 5 out of 5 by from Brilliant dimmer Grid switches offer a great solution to mixed switch / dimmer requirements. Really nice dimmer - good solid terminals, nice soft start and no flicker. Worth paying that little bit extra for.
