Faithful Braun, at the end of my previous Braun shaver 5643 series (dead battery after 8 years of loyal service), I am inclined myself on the latest addition to the range. It suits me and works like the old with, in addition, the possibility to go in the water. By cons it has the following disadvantages had no precedent: - It does not work when plugged into an outlet (therefore unusable when the battery is discharged While I have used my previous several months after his battery was HS before acquiring it.). - The position of the mower, and perpendicular to the razor closer makes it less easy to use - The shaving head being in a single block grid can be changed only, and maintenance becomes more expensive! Like what progress is not complete and if obsolescence is programmed (this remains to be verified), the 2-year warranty seem very low. An additional year warranty is provided but you have to fight with Braun to get it !!!
