The problem I've encountered is that the Mach 3 Turbo System gets quite expensive. It is suggested by the manufacturer that you change blades when the blue strip is gone. If I follow this guideline, I end up changing blades about ten times a month. At $15 for 8 blades, that comes to almost $20 per month just in blades! For a shave that's smooth but not as close as I would like, that's a bit much.
