The best product I have bought for my camera. It makes my xti look like a large pro camera. and I love the ability to turn the camera 90 degrees and shoot.I have lots of battery life. I mean lots! the camera sits in my case ready to go for days and I never have to worry about running out of batteries or recharging. I charge it once a month, and I am good to go.I also like the AA battery insert, instead of the rechargeable, I could go into any store and buy AA batteries and be ready to go.I had no problem securing the grip to my camera. I was just careful to install it the first time. I will never take it off!
