Bests & Worsts Reviews from Amazon

This has to be one of the worst EOS accessories Canon has ever put out; hopefully they will revise its design soon. The grip does not rest flush with the bottom of the EOS 20D regardless of how much you torque the nut. The small amount of play is annoying, but there is a much more serious problem in the form of intermittent power interruptions. A medium-heavy lens (e.g. 70-200mm 2.8) and a flash cause enough flex in the BG-E2 when you hold the camera by the grip that the electrical pins on the grip lose conact with the terminals in the 20D body. Quite unacceptable for anyone who needs a reliable camera for active work. There are work arounds in the form of shimming the grip, but Canon should have done a better job, especially considering how wonderful a camera the 20D is.
