I Came across these on Ebay. Seller says inventory from Factory who made them, guaranteed quality control checked for proper working order. Shipped from China .... I always regretted selling my last perfect operating pair. This is the 7x36EDII version. Was there a EDIII version or 4th ? . Seller from China does not except returns, has good feed back with buyers saying as Described but Ebay always refunds total purchase cost if purchase is not as described. Any thoughts ? .... Thanks
