The blades are not cheap, although you can use any Fusion blade on any Fusion razor (no need to buy the most expensive ones) and they last a long time, but my shave with the Powered Gillette razor are an order of magnitude closer with the battery powered razor. Not to be confused with other Fusion models.
Mine is the straight "Proglide® Power®" razor, but they have the Flexball® models out now.
