I had the misfortune to replace my kitchen sockets and switch spurs the other day with all MK products it used to be back in the day that these were amongst the best to use good size terminations and robust screws for tightening up. These newer products ( I say new they may have been in production sometime now) have terminations and screws that I'm used to finding on cheaper products particularly the terminations on the switch spurs which I deemed undersized on the supply size for two 2.5 conductors and inadequate screw heads. I'd appreciate any thoughts on this
