I to got burned by buying counterfeit razor blades . I bought 24 M3 power blades from Mayimba55 . When I received them I sent in a positive feedback before I even used them , sound familiar ! because I still had razors i did not use them right away but when I did they gave a rough shave . I didn't know what to think that never happened before so I used another and same thing so I opened another package and the SAME thing I couldn't believe it . I started looking around ebay to see if something was being said about this and I found in reviews somethings and also found the web site fakeblades.com I would suggest next time you buy razors try them first before sending feedback . I have now filed a dispute with pay pal and hope I get my money back .
