Quick charge (classical one hour to use equivalent maximum), shaving three levels (sensitive, normal, fast) according to the time you want to devote to it, three heads will obviously fit perfectly the curves of your face for a very, very good result (at this price, this is the least that one can expect from a razor). All of which can be used with or without shaving foam.
The mower (which fits), wide enough however is not super accurate and represents only a "plus" that can not stand competition mowers reserved solely for that purpose.
Review: very very good shave whatever the mode used, one can even say that the performance is outstanding (a smooth shave and very close). A mower medium that nevertheless has the advantage of providing a more (called stubble with maximum cutting height 5 mm).
Is the price ... (5 stars minus 1) a user must bet on the longevity of such a razor to monetize (2 year warranty).
So a razor that is a "must" but certainly a "must have" ... to you to see (I was hesitant to put three stars because of some points that I think are improvable priced but considering the sharpness of shaving four stars actually seems therefore appropriate with reservation).
