Bests & Worsts Reviews from Amazon

I have never wrote a review and I buy things on Amazon all the time. I saw a few other people write reviews that said that these blades were not shaving as well as the originals that came with their Schick razor. I bought these because they were a few dollars cheaper. They did not come in a box which makes me think that they may be returns or expired(if that is possible). What I do know is that these blades do not shave as well as the originals. I shave my head almost everyday and these were giving me razor burn from the first time that I used them, which is very unusual because new Schick Hydro 5 blades usually work wonderfully. I returned and bought the original ones that come on a box for a few dollars more.
