Nikon does suck, had extensive dealing with their service last year and it was root-canalesque.
One optic was sent back to me with the same debris STILL in the view, they didn't even open the scope. They thought I wouldn't notice the huge dust specks in the view.

I had to stay on their asses constantly to get several optic items repaired. I did finally get them back and fixed, but overall it was awful...done with them. period.
