That's the key...you paid for a product; it should function the way it was designed. Glad Nikon finally came through, but that just seems so exhausting.
I accidentally dropped my D700, MBD10, Kirk L-bracket and 28-105 lens. Dropped off the lens and body at my local authorized repair facility and had it checked out; they found that the AF was slightly off, was it liked that before or after, I don't know. I showed I purchased it earlier (I was still within the warranty period) and it was fixed under warranty repair. No questions once I provided the receipt. I wish Nikon USA service was as reliable, responsive and quick as California Precision Service. (I am basing that opinion on what I read; I have zero experience with Nikon USA repair, just CPS.)
