Summary: I purchased this item because it had 4 heads or blades. What a mistake. Head is huge. Pay attention to that because doing your upper lip is a chore. It is just too big. For a buck fifty it went back. I got the three head model, $84.00, and i couldn't be happier. It is easier to use, the head moves in and out with pressure, and that is a great feature. Also, The head is smaller. I mean, its still a three head but it is comfortable to use.
Summary: I have had 3 previous Panasonic wet/dry shavers. In general, the linear blade design is superior to others I have tried. This model is a disappointment. Shaver head is so wide that for the contoured part of the face, only 1 side is cutting. The center part of the shave head doesn't really do any shaving. This makes shaving take longer. After a couple months it is causing skin irritation. Battery life is also short. I get 4 maybe 5 shaves in 1 charge.
