Like many folks, I thought the vibrating feature in many of today's razors was a bit of a gimmick until I got my hands on my trusty Gillette Fusion ProGlide Power Razor. The vibrating action actually helps the razor glide more easily across the face, resulting in a better shave with less drag (and, thus, less razor burn). I was reminded of this fact this morning when the battery died in my Fusion. The shave had markedly more drag and was not as comfortable. If you still think the power feature on these razors is just a scheme to get you to pay a few more bucks for a razor, think again. You'll definitely notice a difference.
