MK Logic Plus 2-Gang 2-Way Dimmer Switch Mains/Low Voltage 300W White is rated 4.1 out of 5 by 7.
Rated 1 out of 5 by from Nothing like as good as I expe Having just replaced all my sockets, switches, phone TV ports etc with MK I finally came to sourcing this dimmer. What a disappointment! It was not cheap and I expected flawless operation with the Philips dimmable LEDs I bought at the same time. After taking the time to rewire all the lights and then the dimmer switch I was left with and annoying buzz on fully lit and dimmed?!?! The old, silent (but sadly - non matching) dimmer went back on. Needless to say this switch will be returned to Screwfix and I'll find a better quality non MK matching alternative.

Rated 5 out of 5 by from Expensive but quality product I have replaced my dual dimmer switch twice, one for excessive buzzing noise, the other as it tripped out when it got too hot plunging the room into darkness. Both of these were from the cheaper end of the market. Good value I thought until my wife became too scared to use them in case it caught fire when I was away. Consequently, I went for the expensive end, the MK version and I have not been disappointed! Very quiet usage (we can't hear any buzzing) and runs so much cooler than the cheaper ones I now understand what my wife's concern. The slow start up is great so you're not blinded by dazzling light straight off. Too early to advise on reliability but I'm much happier with this one.Should have invested in this from day one!

Rated 5 out of 5 by from Nice Dimmer Quality well made dimmer. Fitted into 25mm deep box so patress supplied was not needed. Nice finish, 30mm screws supplied were right length. Works well, no buzzing.

Rated 5 out of 5 by from Best dimmer by far Having replaced a cheap-and-nasty BG unit that had started fizzing with one of these, the difference is immense. I particularly like the slow turn-on of the lights to extend bulb-life. Noise-wise, it is quieter than the BG but still noticeable when standing close by; but as far as I can tell, that is the case with all dimmers.

Rated 4 out of 5 by from A screw loose This comes with a spacer which means the workings at the back does not need to go as far into the recess. However the screws are only 30 mm and will not reach. It is necessary to buy longer screws. With these everything becomes straightforward.

Rated 4 out of 5 by from Good Dimmer Very good dimmer, I like to use MK if I can but they are a bit expensive but you get what you pay for. Make sure you have a deep metal box in the wall as using the supplied pattress for a plaster depth one makes the switch bulky and even then the space in the box will be tight.
