I wanted to upgrade my Olympus lenses and Used Photo Pro (UPP) had what I was looking for in the condition I wanted. I chose standard delivery, and they were delivered in three business days. I have sold equipment to UPP before, but this was my first purchase experience. The lenses were as advertised and, because they were in the price range specified, the warranty was a full year rather than 180 days. I am very satisfied with this dealer.
