I picked up a set of binos that were described as like new in the box, with all accessories. They showed up without the tripod adapter and the diopter ring wouldn't adjust properly for me. If you had perfect 20/20 vision you would never have known, so I didn't really fault the seller for it. I did contact him and ask if he ever noticed a problem and he said he hadn't, but instantly offered to cover the cost of shipping to Vortex for warranty work. I didn't take him up on that because I felt I got a fair deal otherwise and I honestly don't think he knew anything was wrong with the binos. He did send me the funds to cover the missing tripod adapter. Out of 20+ transactions between here and AT, and around 80 on the the big auction site, I've never felt really "burned" at the end of a deal. I HAVE found myself buying more stuff from the classifieds here because everyone has been so good to deal with.
