Loads of photos of the plastics breaking though, but I think that I'll do is try taking our old metal one apart and see if I can fix it, if not get that one, thanks.
I'm not on commish or anything, but all the breakages I could see are the locking tabs at the bottom. I've never used them, as I assumed they'd break based on the reviews. I did sort of what this person did.
Fwiw the washing line I linked has >40k reviews.
