Review title: Not so tight grip
Product review: This definately provides an extra long battery life, but there is a small problem with the dial grip/holder. It would be nice if this actually locked in place, as opposed to just dial tight. I have found that I might not notice that the grip has loosened, to where it was about to fall off. I find myself checking the dial, to make sure it's tight, often. Otherwise, I love it, and can't imagine my D200 and D80 without it.
