Phottix Battery Grip & 2 Rechargeable Batteries for Canon EOS 60D - replaced BG-E9, LP-E6 in original quality! Battery Pack (Electronics)
Unfortunately I can not give a positive response, even though I had been looking forward to the article. Reasons: 1. Steering the battery grip is broken (aperture, exposure ext. Not adjustable) 2. Batteries are only occasionally detected in the grip
