I ordered this battery grip from Minadax Because I wanted the ease of use with "Portrait" without having to twist my hand and fingers across my face everytime. Why Minadax When I could have bought the original from Canon! Well the price was way way below deed of Canon for the exact same thing. Plus, with the Minadax battery grip I got the 2 Canon battery holder plus a 6 AA Battery Holder, Which I find a very good thing indeed. The 6 AA Battery Holder Allows you to use AA Batterys, Which you can buy almost anywhere, if you are away from home without your spare Canon Batteries When You Need them. After using my camera, a EOS 350D, extensively, with the Minadax battery grip, since I bought it. I can honestly say I did have had no trouble or problems with it to date.
