I never take mine off my camera. Holds more battery's allows you to shoot in potrait in comfort. Its a standard bit of kit for me


Makes the camera feel a lot better.
Much much easier to hold now.
Only have one niggle. Can't have the camera on the tripod when using my 70-200 F4L and the grip, as the grip catches on the tripod when mounting the lens on the tripod..
It's fine on my mates tripod tough.
