the +:
-The vibration is very well damped by the 380-S4 compared to my old braun of ~ 2005. (Finished vibration galore in hand)
-The effectiveness of shaving
-the possibility to raze the underwater
-Charge fast enough
-the screens that swivel to follow a few degrees shaving and that cushion supports it. (Very stupid but very pleasant system to use).
In short a good value I recommend.
EDIT: I spend 5/5 to 1/5 after 3 years since the integrated batteries no longer hold a charge ...
The price of batteries 2 official on Ebay over 35 and no documentions exists to date to dismantle it.
The shop repair cost is the price of a new unit ... I'll point me to a similar model which uses mains this time !!!
