After Braun 2 grills and a Panasonic 3 grids used respectively 8 and 6 and having cracked both by the battery, I wanted a model 3 charger without power grids. Hence my choice for the Braun Series 3-300. At 1 First, it seems very light, all-plastic. If shaving is really light, a caress compared to my previous models, it's hard on a 3-day beard, the head (razor!) Was taken down when I pressed a little ... and grid Extra's also really light. In short, disappointment, remains to be seen in use ...
