Consumer Review of PT720 Powertouch Rechargeable Cordless Razor. The PT720 provides a closer shave than most electric razors in its class. The razor heads are more flexible, allowing the razor to more closely follow the contours of my face. However, a few missing options from the more advanced (ie expensive) electric razors ensures that the PT720 cannot replace a higher end model. It does not include a pop-up trimmer, and also gave me razor burn, though that is also a result of my sensitive skin. Overall, I would recommend the PT720 for someone looking for a mid-range electric razor, but I would also strongly suggest spending the extra money for one of the more advanced products in the Norelco electric razor line.
