Gillette mach 3 Review

The Gillette Mach 3 is the longest razor that I have ever used.  I have fine hair so it does not grow quickly or thick.  I never have to worry abour this with the Mach 3.  I get an excellent shave everytime.  The best thing is that when it is close to changing the blade the blue strip turns to white.  How much easier can it be for the consumer?
