Ok folks, curiosity got the better of me, so I went out to the loft tonight and set up my system with this new lead, scanned 10 separate rings, several times each, and every time they registered, so, all I can say, is it works, which is the only thing you can say about any lead, irrespective of the cost :-/ so take from this what you want folks if anyone wants the contact for this company, I will happily pass it onto them
