I like crabtree when it comes to switches and sockets and other accessories. Good solid screw connections. However I found recently their sockets have been changed from a round terminal for a square one which doesn't feel so secure. Anyone else found this? Not sure on how the price compares to GET or MK?
Don't know about the change in terminals as I don't install their stuff often enough, although on the whole I'm a fan of Crabtree. That said, I do remember installing a single gang socket and thinking to myself how stupid the combination of terminal/screw locations was! Nearly impossible to install one in a corner without turning the accessory every which way to get to all the screws.
