Well all i can say is, that your experience is very different from mine, the failure rate was becoming a joke, we were at one time sending whole boxes of accessories back for replacement. Another example where accountants have stuck their noses into a quality based business and ruined it's reputation...
I can't see much wrong with the Crabtree range myself, solid bit's of kit from what i've seen and failure rates are to say the least, down drastically!! No experience with the Hager range so i can't really comment. One so called quality manufacturer i wouldn't entertain is Legrand, expensive crap!!
ABB's modern stuff isn't too far behind them either... lol!
