Review (5/5): Running perfectly for over a year now...
I have had this shaver for a little over a year now, and am still very happy with it. This model is no less powerful than my two previous Norelco razors (both of which lasted about 12 years each). It is however the quietest Norelco I have owned, and perhaps because it doesn't buzz like an angry nest of hornets some people think it isn't as powerful as their older Norelcos, but it is.
This model cuts nice and close, so if you haven't used a Norelco before, don't go grinding this into your face with force and then complain that it skinned you alive. As the instructions state, a Norelco is meant to be glided across your face in smooth circular motions without using pressing force.
This model stays charged for about 2.5 weeks when shaving every other day and about 10 days if you use it every day.
If you are looking for a nice Norelco shaver and don't want to waste money on gimmics don't actually provide a better shave, then this 7110x is a good choice.
