"I've bought a couple of the Varilight sockets now. The terminals are easy to wire, the switches generally have a very positive action when turning off/on and the colour matches very well with the Varilight dimmers and light switches.
A problem that you may encounter (as has been noted on other colour variants I believe) is that due to the screwless faceplate, it can be somewhat challenging to clip the plate on if you don't have perfectly flat walls. I've personally found these to be OK (despite having a 1920s built house with anything but flat walls!). The dimmer switches have been more problematic (but again, with enough force, I've managed to clip them on!)."
