I received my MB-D11 yesterday and am very happy with it. I have a little tip for those that complain about the little white contact cover that comes with the MB-D11 getting lost. It will fit perfectly behind the battery in the MS-D11EN holder for the EN-EL15 battery, it even has a tab to fit into a slot behind the battery. My D7000 weights 4.75lbs with the 24-120mm/f4 lens, MB-D11 w/batteries and Black Rapid Sport strap attached. I have not seen any movement or slack between the camera body and the MB-D11 with the rubber cover inserted in the slot provided. You can find the slot in the manual on the first page after you open the manual in diagram B.
