Low Voltage / Mains Dimmer Switch 1 Gang 2 Way 400W is rated 4.4 out of 5 by 8.
Rated 5 out of 5 by from Excellent LED Dimmer I bought this to use with dimmable LED bulbs in the lounge. No flicker and easily fitted in the wall recess with the supplied screws. Push on Push off and runs either 3 or 6 bulbs with ease. Liked it so much, I bought the same unit for the Dining Room

Rated 2 out of 5 by from Not LED compatible? Probably fine with incandescent bulbs but caused (dimmable) LED to flicker and buzz like mad. Not really on in 2017.

Rated 4 out of 5 by from Check the item before leaving!!! Bought this to replace faulty item. When I opened the pack I found the dimmer module covered in brick dust and the switch face plate grubby. This unit was obviously used, in what working condition who knows?!! Exchanged but it's probably gone back on the shelf! As the replacement worked (and I assume is still going as I've not had a call) that's why it gets a 4 star, as for Toolstation? Well they get 1

Rated 5 out of 5 by from Dim n dimmer I bought this dimmer switch a while back, and it does what a dimmer switch does. Turn the knob and the light gets dimmer. I suppose the clue is in the name.
