I shave from the beginning (10 years) with electric razors. First I had a Philips with 3 heads and a Braun Series 3. I got there one week this Series 5 5020s and I am really delighted with this razor. The first impression is that it is a bit heavy. It passes very quickly got used to it from the first shave. Its vibrations are not disturbing either. If it vibrates too much to your taste change your grip a little closer in the head and the difference is significant. For shaving as such I am really delighted. His head is moving in many position and follow the contour of my face (FlexMotion system I think). The chin, jaw problem. It is very effective, no need to spend many times to the same place to cut all the hair. The only place where it has a bit of evil, as my previous razors is at the base of the neck where I have to spend about 5 times to cut all the hair. None of my previous razors to come, may be my hair is recalcitrant to this place ^^ It makes a little noise but it is reasonable. In terms of quality shaving: he forgotten very little hair and really close shave, skin is running. No itching after use or irritation. I shave and basta, no lotions or otherwise. No bad feeling the passage of the razor. I tested on 4-day beard also. He has a tendency to tweeze a few hairs but it's very reasonable. To avoid that the hair trimmer in the first pass the bill.
Maintenance is easy! we can move the shaver head under water while leaving the function or remove the brush head to move inside.
After a week I finally adopted. For my job I have to have a neat appearance and shaver completely filled this mission.
