Competition Imp couplings are about ?40 each. I’m still wiping away the tears after just finding that out. I’d recently fitted 4 of the “Lotus” variety (at ?75 each all-in incidentally).
This info might prevent somebody else being “done”- just google imp rotoflexes for suppliers.
Worzel…John,
Did you buy the ‘Lotus’ ones from Ebay? ?75.00 gbp each is a big con in my humble. Esp when they are not right!! The items on there now are imp non HD. The Link above has them listed @ ?42.00
