Pro: It will give a very close trim and will mow down 4 days of growth without much effort. The hair that's left is about equal to 5 hours of growth after I shave with my Braun 7 series. It would likely be short enough that you could get by with just the OneBlade for shaving for work as long as you don't care about 5 o'clock shadow at noon.

Con: It will really destroy my neck if I'm not very VERY careful. I feel it damaging the skin, but it doesn't bleed immediately like shaving with a blade. Bright red rash and/or surface blood. This turns into dark red "scabby" looking skin. It doesn't hurt much by the afternoon but looks terrible, like I tried to shave with a sharp but uneven/nicked blade. It isn't designed for immersion, but it works much better with a little something wet, either soap or hair conditioner on the surface to help it slip on the skin.

The only positive about the negative, it doesn't seem to cause ingrown hairs even though it looks like it should.

I haven't had it long enough to really comment on how long the battery lasts. I don't know if it would do a daily full shave for two or more weeks yet, and I don't know how long the blades last.

The battery easily lasts two weeks with enough daily use to "shave" my entire face. The blades so far seem to last about six months with two or three minutes use every day.
