What do y'all think??????

What a pile of shit! You ain't never going to keep a cartridge razor sharp with that crap, it's just marketing bullshit! cartridge's are disposable by design if you're having trouble with irritation and absolutely have to use a cartridge razor you should try a Gillette contour plus it's only got 2 blades in it or something similar, or try a DE razor.
 
It may work, I heard that a lot of the straight razor guys are getting rid of their sharpening stones and moving to rubber....
You lot are so cynical, just because Bob Ross is from South Korea and so is the company who markets this shaving revelation it doesn't automatically mean she is a marketing shill. I am sure you are all wrong and she will continue to post and become a well established member. I am buying one and I don't even use cartridges.
