I recently had a brain fart where I broke the battery door off my D7500.
Fortunately the following week I was near the Nikon service center in Mississauga , Ontario.
I stopped by and a service person came out to help me. I expected to leave the camera for the day. The service girl went in the back to see if they had a door. She came back with 2. Showed me how to replace it and then handed me the second new door. I asked how much and she said. Free.
Thanks so much for the great support!
