Excerpt: I found the D7000 a bit small in my hand, while its a great camera the thought of a battery pack/vertical grip seemed to be a natural addition. I find the MB-D11 very comfortable and solid, I've only used it for a short time but I really like the way it feels in my hand. Its quick to detach to change out the battery and although the connection is a simple design it works well and holds securely.
Excerpt: The build quality of this Nikon battery pack is far superior to third party brands of this type. Heavy duty and professional, this battery pack doubles battery life, and allows for vertical photography with ease. High price, but worth the piece of mind that the product will work on command.
