What is the difference between Gillette fusion power/mvp/gamer/phantom?

Hi I'm Pedro and I work for Gillette. The only difference between these razors is the design and colour scheme. We just want to offer a wider choice of designs. The difference between power and manual is that the Fusion power requires a battery to make it vibrate which helps raise the beard hair for a closer and smoother shaving. The Power blades also have an extra coat to make them glide easier across your skin. I hope this helps and feel free to follow me on Twitter @GilletteUK
