Jury's still out...
I'll admit that it does cut hair, but after about 2 minutes, it sounds like the battery is dying.  I'm still working with it.  I charge it overnight, try it out and it still loses power after a couple minutes.  I think on a regular basis, it'll get the job done.  But if you wait too long and have hairs escaping your nostrils, it may not be up to the task.  Just saying.
