I was afraid of the material, now i'm flabbergasted by inserting the rings. - Vortex Harness Strap Connector Set

Well, the title tells it all. Getting these things on without twisting them round and round is laborious to say the least. I installed seven sets on seven binoculars and it took me about 3-4 hours work, the resulting corrections after putting them on without a twist is a chore and as the rings are very tight with what looks like a sole stainless steel slit through which the rubbery strap must be inserted, my fingers took a real beating by taking them off and then reconnecting them them the other way 'round. But, once on properly, they seem fine.
