Excerpt: I am professional photographer and i am very content with the battery magazine. It hasn't had any problems. The plastic seems durable but if it were thicker it would be more sturdy. However its great and has not given me any headaches.
Excerpt: I like the fact that the magazine came with my grip but I'm surprised at how fast it will drain 6 AA battereis. Not complaining because it is a life saver but i was caught off guard at battery life.
Excerpt: I purchased with my new camera not realizing the battery grip already came with one. However, I dont regret it, especially considering how reasonable the price is! A must have for out of studio shooting and weddings.
Excerpt: When I'm on the road and the camera batteries die, this is a great back up. It uses AA batteries that are available almost everywhere and they will last long enough to recharge the dedicated batteries. Thankfully, I haven't run into this situation but, better prepared than not.
Summary: Received it yesterday, put it in my EOS 5D ii, works flawlessly, all the buttons function well, and I didn't feel any shutter lagging. I like it, giving my camera a cool new look. attached to my camera, it feels solid, compared with OEM product price, this one is really a good deal.
Summary: does exactly what I want it to, only a fraction too slow, my primary source of media comes from live entertainment where I need to be fast, this delivers at speeds I need some of the time, but not always. I would recommend for anyone who needs longer battery life, avoid non-Canon batteries though.
