I've been following the forum for quite a while. I was using the Mach 3, then during my quest for a closer shave I went to walmart and bought the Schich QUattro - ouch, it irritated my skin, I could feel it pulling my hair. So to make a long story short, I saw the mantic videos, bought the Merkur 3 piece set, and a 38c and a HD, as well as a Rooney Stubby 2. I tried the sample pack and decided on the Derby's and the Feather's. Infact my friend and I bought 5000 Derby's and split them, so I have 2500 Derby's and I got some feathers on ebay, so I won;t have to worry about blades for the next 30-50 years.
