Review (2/5): For Facial Use Only!
First off, you shouldn't be shaving anything but your face with this razor. Norelco's older models seem to be heavier and have more powerful motors; this thing is more like those old electric lawnmowers that couldn't cut grass more than 1/2" high. It gives a middling shave on face and neck, but it certainly can't handle the forest around the Great Oak Tree, if you know what I mean. It also won't do armpits or backs or legs very well.
I'd go with an older model that is heavier and seems to have a more powerful motor. You'll need it to clearcut your axillary forest.
