Although I haven't personally DE shaved, I have seen videos. The downside from my obersation appears to be that you have to shave SLOW, meaning if your running a little late for work and have to shave then a DE razor isn't for you. I also observed that it seems you can only have one direction and that's down unlike a straight razor or even a regular stick razor. Also it seems like it would be a bit harder to follow the line of your beard, if you have one. Seems that DE shaving is mainly for people who shave off all of their facial hair. All in all the biggest problem seems to be the fact that you have to shave slow, can any of you actual users think of any more negatives in DE shaving?
