ZorSy: I'm not sure where this kind of reviews published on DPR are taking this site to: I don't work for or with Nikon, nor have D800 for that matter. There have been grips and 3rd party accessory for cameras before, never "reviewed" in this fashion. It was part of discussions and comments about the stuff one can buy on e-bay, for good or bad (none has to tell us it's cheaper than OEM stuff, we know that anyway). Why did DPR pick to this way so of the sudden is a bit of mystery. Independent reviewers can go the way they want, without question - following the "line of money". But why with D800 grip? I'm sure the number of MB-D10 clones and variants sold over years for D80/90 is plain vast compared to the number of D800's out there - yet never even remotely mentioned, virtually non-existent. Hmm..
But this isn't a knock-off grip from eBay, this is a knock-off grip from Amazon. Who owns DPReview again?
