Query: Choose Canon brand

I wanted a reliable second battery for my camera to take on an extended overseas vacation. I was concerned about "OEM" off-brands (which may be OK, but some reviewers advised caution). I was not disappointed by buying the Canon brand named battery which appears to function exactly as my original battery. The Amazon price was much better than I could find locally, and the delivery time was just a few short days after ordering.
