Have you ever purchased a Nikon (or related) item for your Nikon camera and found it failed to meet your expectations? Share your stories here. BTW, I'm not "anti-Nikon", actually I'm a Nikon fanatic. But I do realize that not every product is a winner and I'd like to help everyone else out there avoid those lemons. Thanks!
