this review title is: good shaver but not worth an upgrade and the content is: i am a year norelco user who also owns a five year old norelco which was the top of norelcos line when purchased in my opinion the new smart touch line that uses the heads is not worth the upgrade i buy new heads once a year which makes my older shaver feel like new the only real reason to upgrade a quadra norelco is if the batteries are failing and there are numerous places now where you can have your dying batteries replaceddo not fall for the latest is always better line.there are other information for this review, one is this reviewer did not purchase it and the other is 36 people think this review is helpful.
