Negative Positive
Title: piece of garbage
Review: The grip is comfortable but is horrible when using the camera at an vertical angle. when shooting vertical the battery grip loses connection and the camera loses power. i had to finally resort to taping the the battery shelf in. it just isn't built well and the locking mechanism doesn't hold tight. i also have had issues where the grip would cause my camera to freeze up and i would have to remove the grip to get my camera to reset. pay the extra and get a canon battery grip.
Is the review positive or negative?
