Great product but read the wiring instructions before connecting the cable , product gets warm but this is correct. Dose what it said,connected to 2 different lamps with different wattage and able to dim both to the same lux of light

Flimsy. Had to purchase a more expensive one in the end as this all broke apart on fixing up.

    Buzzes loudly and fiddly to install.
  

*by R***L on Reviewed in the United Kingdom 🇬🇧 on 20 October 2016*

It's very fiddly to wire and there's almost no room between the cable clamp and the connections on the inside, and the damn thing buzzes. I can't return it as the screws are quite soft and I managed to damage them while doing them up tightly enough to hold the cable in place but if I could I would. The buzzing is loud and very irritating. Apparently this is likely to be a design flaw, according to an electrical engineer friend, rather than me just getting a dodgy one. I might have been unlucky, but you won't know until you've connected it. We've got a different make of switch on an identical lamp in our bedroom and that is totally silent, so I know silent ones are out there. Sadly we can't buy a pair for that one as it's twenty years old now!
