Purchased a D800 about 2 months back, has been waiting to add a vertical grip to it eversince. First heard about the Meike version, then saw the Pixel Vertax. I have had good experiences with Meike Grips from D300 to D700 . Waited for more reviews of the 3rd party grips before decided on this Pixel Vertax MB-D12. Made the purchase and now awaiting for its arrival. Will add my review of it soon. Cheers!
