Query: Very pleased with these batteries. I've taken probably hundreds of photos on the same charge. Great replacement battery!

I'm always a little skeptical and cautious with off brand stuff. I have an older Canon digital rebel and will eventually upgrade it so I figured for the money, if these batteries weren't that good they'd at least get me by until I upgrade. Well since using them... actually I've only used one of them so far since it keeps on going, I've been VERY pleased.
