Re: WTB: Nikon MB-D14 grip
Consider yourself lucky then. There have been tons of reports stating that the 3rd party grip for the d600 has caused problems in the electronic connector.
Ive had 3rd party meike grips on a d300s a d700 a d7000... All worked flawless and as you stated, looks identical. So, when I got a d600 I went ahead and got another grip. Took two days before the symptoms started. Replaced it with another one... Same story. Maybe it's a bad lot... And time will solve it. But for now, I have the genuine nikon and have had 0 problems
