Here is a great video review of the new Braun Series 9.
It’s by far the best electric shaver on the market, but as the creator of the video explains, you might not need this model.
If you have a thick beard then yes consider it. But if your beard is not very thick, then you don’t need this much power.
The Braun Series 9 has the most power out of all the other models, and only the newest Panasonic shaver can compete with this unit.
