What a disappointment! When it was "a little" beard's going, it is rather efficient, very light and handy, and convenient to use (waterproof), but since we have a fairly developed beard .. it's a fight to get the desired result!
It "pulls the hair" (very painful) must board to finally shave 50,000 times a specific area (so it irritates skin), multiple passes of 3 rotary heads seem to change anything .. (long and tedious)
The result is: full of remaining hairs on here and there, so not a clean shave at all, not at all a smooth skin (looks like a shave with tears off), I always had to go another razor to finish my shaving properly.
The moisturizer that can be inserted effectively reduces irritation razor (it's fun, friendly to skin effect), but it lengthens the duration and shaving it remains imperfect. I would add that the moisturizer is nice enough but the final gadget. And even if it's not what I asked for this problem razor, the absence of hair recovery is also less.
Do not expect to shave in less than 20 minutes or to have smooth skin (much less the result intended) with this razor if you have a fairly developed beard (by that I do not hear a santa beard eh just a beard regrowth developed fast enough).
Small precision also: no precision trimmer present or supplied with this razor, only two other "higher" models are equipped (while most electric shavers are generally accompanied by this type of accessory).
Finally autonomy is also quite disappointing but I expected that it would have been forgiven if shaving was good ..
I do not know if this is the system "rotary heads" who is there for something (it was my first razor that kind), but all that was not at all convinced and I think to fall back the foil shavers, which more efficient air made me (or so we should perhaps tapper in SensoTouch 3D overpriced ..)
NOT RECOMMENDED for long wiry hair and beards!
