Use it well, and carefully. This is an aggressive sucker-go slow. I think some of my closest shaves have been with a Micromatic.
I've wanted to try the SE thing for the longest time but the GEM razors give me a bad case of the heebie jeebies. Maybe an injector, anyway it looks like a good one, good luck with it.
Keep the flat shiny piece against your cheek and then vary your angle just a bit to get it to cut. This is NOT a DE! If you use an angle of attack like a DE, the MM will do just that.
Listen to the munky. He knows what he's talking about. The first time I tried my GEM SE I literally touched it to my cheek and cut myslef so bad I had to use a band-aid for the rest of the day. Then I figured out I didn't have the blade in correctly and I didn't have the correct angle. The blade needs to hook in and should not lay flat if done correctly. There should be a slight gap between the spine of the blade and the razor. This video helped me out quite a bit. http://www.youtube.com/watch?v=lUG2B_-D0d4
I had problems with the OC Micromatic at first, and went to other SE razors. After working on my SE technique with Gem 1912s and others, I came back to the OC Micromatic and couldn't remember why it had been so hard for me. Just another good razor now. That said, I think I do like the 1912s a bit better, with the Bullet Tip Micromatic a close second, and only then the OC version.
Don't be scared, it looks kinda scary but I just used mine for the first time a few days ago. Came out on the other side with some bad razor burn but no blood. The experienced guys are right: load it right, prep right, and go slow and there's nothing to worry about.
