Gillette Mach 3 Refillable and Disposable Razors Review

I received my first Mach 3 razor by gillette on my 18th birthday and have not changed razors since.  In that time I have used several disposable brands while on vacation and have found the quality to be much worse.  Other brands tug on my facial hair and feel dull after one shave causing knicking and bleeding while shaving.  The Mach 3 seems to stay sharp and not knick my face for a couple of weeks before I have to change razor blades.  The new replacement blades for the mach 3 are really nice they have a little color indicated strip that lets you know when you should change the razor head.  This is an awesome feature I have found that it is pretty dead on and warns me of the razor being dull right befor it actually becomes to dull to shave with.  My only complaint with the Mach 3 is it provides you with a premium shave but it also is very expensive to replace the blades I think the last time I bought cartridges it was 12 dollars for 5 blades but Im not really sure.  All in all I love this product and will continue to use it.
