If you look a couple of threads down you will find 3 favorite blades. The Med Preps are listed as a top three on quite a few lists. It would be more than a little insulting to imply that all these shavers are following a herd mentality and don't really know what they're talking about. Derby is on somebody's list - which I think is unbelievable, but that only reflects my experience with them. If they work great for you be happy with them and buy them by the 100's. I did buy 100 med preps because they work great for me and I get a week from each one.
