Negative Positive
Title: Good price, lousy performance
Review: I bought this product a couple weeks ago and at first it seemed fine, but then I noticed that when it was turned on, the control wheel becomes uni-directional. What I mean by this is no matter which way you turn the wheel, the control only scrolls in one direction. This is OK, but frustrating, for some things like ISO and white balance, but it makes the exposure compensation wheel useless. It only moves in the negative direction and once it reaches -2, it is stuck there and will not come back up. This is true whether using the control wheel on the camera or the one on the grip. I am hoping I can return it and if so, will spend the extra $$ to get a Canon grip.
Is the review positive or negative?
