My second unit was a refurbished unit and it had a battery issue. Instead of returning it to the store, I decided to do the Advanced Replacement Program. When I received the third unit, it was wrapped in the same plastic as the retail packaging, so I think it's a new unit. This unit appears to be working perfectly, except there's some minor damage on the top-left corner of the frame. I think it's a manufacturing defect; I may exchange it again sometime near the expiration date of the warranty period.
