Query: Wonderful product, but pricey

This is an absolutely wonderful product if you don't mind the fairly high price. If you've done any research, you already know that there are similar products available for less. I own the Canon PowerShot S5 IS and it (and other Canon cameras) run on any brand of AA batteries.These batteries do seem to have a very long life in between charges. Occasionally I won't have any other choice but to purchase regular batteries when I'm out and I'm desperate and it always seems like they die much more quickly than when I have the Canon batteries in the camera.Bottom line: I'm very happy with these batteries and you will be too.
