Input: I was very happy when I recieved the item & so excited about it. But after one day studying of the camera, i was so disappointed because the Mode (top of the camera in the right side) is defective, I can’t turn it properly & so difficult. Then i tried to contact the (seller) in their email but i only had one responce. Not really helful at all, I’m not used to ordered online so I don’t know where i can sent back my item. I’m glad i call NIKON & gave me instructions how to sent it back here in app. ! Really bad experience!!
