Review (5/5): Excellent shaver
This is my 4th Norelco shaver and it is the best yet.
It is an exceptionally quiet shaver. There is more sound from shaving than the motor itself.
The shave is very comfortable. Shaving heads have cushioning and the floating mechanism allows for a very close and comfortable shave. It's also easy to clean. With my earlier Norelco's the process was daunting enough to make me lazy. With the 7140, it's easy enough to do after every shave.
I have been using it for a month and have not had to charge it.
