"It's odd to be so pleased with something as simple as a switch, but these really are wonderful.
The build quality is just fantastic - it's just white plastic, yes, but the body of it is so sturdy, and the back (the terminal mounting) so fuss free, with easily accessible terminal screws and generous terminal holes, it's a pleasure to install.
The switch itself operates with a smooth yet solid and satisfying "click!" (not excessively loud though), that you aren't left with any doubts as to whether or not it has worked...
Downsides, only one - I've checked and double checked (I've bought four), and the packets do not come with the little white plastic covers for the machine screws that secure the face plate to the back box. I'm personally not that bothered, it's such a small thing, but I've marked the product down for Features and Value, because I know some perople would expect and / or prefer them to be provided."
