Query: Excellent!

Ive been using this battery pack for 2 years and it is excellent. I also bought a total of 4 batteries. It will last a whole day of shooting. And if it doesn't there is always the 2 spare batteries or AA batteries that can be used as well. The grip makes the camera (black Rebel XTi) feel more comfortable as well as make the camera look more "manly". The grip matches my camera colour which makes it look seamless. It also gives the camera a good feel and "weight". No more arm twisting with the vertical shutter release. It's a well and solidly built grip that still looks brand new after 2 years. And best yet is is a lot cheaper than the Canon equivalent.
