I'm going to get a razor and gillette's blades look like the best to me... but I don't know what the batterys for in fusion power. Do the blades move or something or am I just paying for a razor with a battery in it.

Gillette.com (http://www.gillette.com/en-us/?gclid=CITxypm0haACFdx05QodUT3Zkw#/products/FusionMVP/en-US/index.shtml?utm_source=google&utm_medium=cpc&utm_term=Gillette+fusion&utm_campaign=Brand_08.01.09/)

That's the official web site. It should have all the info you need.
