Haven't had a "bum" product from Nikon in the nearly 50 years I have been using them. Sorry you were unlucky. My D 750, which was recalled was working perfectly, but I sent it in an excess of caution - they repaired and returned it quickly, and for free. There are always individual situations that can sour a person on a manufacturer, but I think that how a person responds, positive or negative, has effects as well. Note - all of my Nikon gear going back all those years still works.
