MK Logic Plus 1-Gang 2-Way Dimmer Switch Mains/Low Voltage 400W White is rated 3.3 out of 5 by 33.
Rated 5 out of 5 by from Excellent Dimmer Switch Extremely pleased with this product. Only installed it three days ago so 5 stars for reliability may be a bit premature but, on the basis that it an MK product which I have always found extremely reliable, I've taken a punt! At the end of the day it's only a switch but even my partner got excited about the nice action of the switch and the fact that when you switch on the lamps illuminate slowly - maybe to increase bulb-life - but the effect is classy! Comes with an expander plate in case the internal gubbins make it too deep for the recess. Not sure if it can't be purchased cheaper elsewhere but the superior product specification on this website that made it clear what kind of bulbs you could use it with caused me to purchase it from Screwfix and also means that I may not be comparing like with like anyway.

Rated 5 out of 5 by from MK 1 / 2 way Dimmer Switch After suffering terrible reliability from switches made far away and sold in big home diy stores, this product is a solid, quality item and not only does the job but has an intelligent warm up delay.I think Mr Henry Ford once said something along the lines - If you need something and do not buy it then ultimately you will have paid for it but won't have it . This is certainly true for electrical products!

Rated 4 out of 5 by from Slow to react Replaced a remote control (IR) touch dimmer as the TV remote kept on interfering and turning it off. Fits in a 16mm back box with the supplied spacer and doesn't look out of place. Slow to react to the on push so first thoughts was it wasn't working :)

Rated 5 out of 5 by from Quality dimmer Bought 5 of these for replacing standard switches. Fitted neatly into existing wall box but have a extra back plate surround in case you need it. More expensive than some others but you can tell the difference in the quality. Well worth the extra.

Rated 5 out of 5 by from quality product This is a quality product with a 10 year manufacturers warranty, easy to fit, good instructions and a useful spacer for if the back box is not deep enough. Point to note, this is also a push on and off as well as a rotary dimmer, something not mentioned in the product description, also check max / min watts before purchase

Rated 4 out of 5 by from Quality counts Its a quality item which does exactly as it should do. Unusually there is a time delay for the light to work of a second or so but once on its fine

Rated 1 out of 5 by from Terrible buzzing Bought 2 of these and they buzz terribly with a standard 60W GLS bulb. Checked MK compatibility chart and these should work without any issues.

Rated 2 out of 5 by from Way to noisy Installation was easy and it's fairly low profile and fitted in a shallow box. Unfortunately it's incredibly noisy (buzzing at all load settings) so I'll have to uninstall it tomorrow and take it back to get a refund. It's installed into a solid plaster / brick wall and still it's really loud. Should be better for the money.
