Mach 3 blades are what they are - if you're buying them you know what you're getting, and have been for years.
Review is about the mach3 handle that came with this . . . it's cheap plastic. I have some older handles that feel much more solid and hefty. This feels like a disposable razor. Yes, it gets the job done, and I bought it as a spare for the gym. But it's pretty low rent handle.
