If you are looking for a trimmer stop reading reviews and just buy this one.
This is great.  Yes, I can get a closer shave with a razor, but I can also get irritated skin, ingrown hairs, etc.  This thing gets rid of the hair without any of the irritation.  If you work in an industry where you don't have to be clean shaven every day, you can't go wrong with this. (and the vacuum feature rocks cleanup)
