Review (4/5): Good if you shave every day and only with this razor.
Prior to getting this razor, I shaved roughly every three days with a Mach 3. This was my first shot at an electric in about ten years, so I wanted to buy a quality product. I have relatively sensitive skin, but nothing too bad.
This razor is no good at shaving longer hair (> 1-2 days of stubble). It pulls the hair and requires ten minutes to do a mediocre job. However, if you use the razor consistently every morning, it does a pretty good job. I'd recommend making one pass on the sensitive setting and then following up with the 'normal' setting.
