Having bought a p100 a while ago and after a light bulb blew it burnt the switch out ! I sent it in for repair and never fitted it untill yesterday, it worked for a while ,1 day and in the morning the light did not work , i removed the switch and noticed the pcb with the Triacs on had completly burnt out ! I do not want to spend anymore money on the switch, they seem to be a big problem with these switches, it cost around £160 to buy and I spent £50 getting it repaired the first time round .Has anybody had trouble with these switches ? it seems if a bulb blows on the same lighting circuit it burns the switch out .
Think I will go back to a £15 dimmer...

It's not unusual for the triac to fail when the lights blow. Especially GU10. But it's not difficult to buy replacement triacs, which you could replace yourself.

Is it worth fixing? I don't know. Unlikely that you're the only one with problems though.
