As an unsatisfied purchaser of a used compound bow on E-bay recently, I learned a hard lesson in regards to what questions to pose to the seller of such merchandise.  As a relatively new E-bay customer, I quickly discovered that some sellers will not readily share the more significant damage/discrepancies with their listing, but will openly share the minor ones.  My purchase involved a seller who indicated the bow was in "good used" condition and related that the only visible wear to the item was its fading camouflage finish.  When I received the bow, I quickly noted to my dismay that the drilled and threaded ports on the mainframe of the bow (where you attach accessories), were all stripped out, making it virtually impossible to add any desired accessories.  This can also be a costly repair, especially if I wanted to bring the bow into a "good used" condition as indicated in the listing.  So please, if you are considering the purchase of such an item learn from my experience and pose a question regarding this feature.  It's unfortunate, but we as the buyer cannot trust that every seller takes the responsibility upon themselves to be familiar and educated about the items they are selling so as to provide an accurate and informed listing.  I hope this is helpful to someone.    Safe Shopping!!!!!
