Not sharp - not at all the Mach3's I'm used to
on October 6, 2010
These blades are not sharp and shaving is just painful.
I should have paid more attention to what the other reviewers were saying... I've been using Mach3 cartridges for many years and I strongly believe these are, indeed, NOT the real deal. Extremely disappointing, considering they're sold directly by Amazon.
Buy at your own risk; mines are going straight to the garbage bin.
