Thanks for the replies, I have sent him a new lead, because .........
He knows what he did with it, he knows I know he's tried it on, the bit that really really f****d me off though was this:
as alot of lurchermen (and women) buy your leads and collars, its a must really that they can withstand abit of water.
Nice and patronising, am glad he found the time to point me in the right direction with my gear.
It would have been easy to name him and make a twat of him on here, but he's done that all by himself, he won't be getting any more of my gear that's for sure.
