I STARTED USING IT IN OCTOBER 2012......NOW HERE IT IS MARCH 2013...AND AM BACK TO USING A REGULAR BLADE RAZOR. EVEN AFTER ALL THIS TIME, I COULD NOT GET A SMOOTH SHAVE AND I DID NOT SWITCH BETWEEEN YOUR RAZOR AND THE BLADE RAZOR. VERY DISAPPOINTED IN THIS PARTICULAR RAZOR.
This razor matches the quality of all of the other Norelco razors I have had. I do like the ability to rise it out after use. The price has gone up so that I could not afford an exact replacement of my old razor. I was unable to afford the razor with the trimmer built in it. Over all, I am very satisfied with the razor.
Tried using the PT720 shaver, exclusively, for the 21 day period but, it stopped shaving close after the 2nd week. I returned the shaver and purchased the top-of-the-line model. Amazing difference!
