I haven't used hozelock for many a year, in fact only when I first started and the system I used had hozelock fittings, they lasted about 4 months before I became painfully aware that there must be better out there, they catch, snag and break all the time, plastic or brass, the size does not help either, too big and bulky.
I changed over to rectus 21 and as long as I buy quality (Parker hannifin) connectors they last a long time.
