Razors so it was possible for me (even good electric razors) as necessary while shaving, it takes time and can not afford any "maintenance" beard is shaved it all is (that's all smooth) or nothing. When you want it, that's fine, but if not, if you want more customization, you must opt for a mower.
This is nice: it is well in hand, it is very handy, there are several cutting heights (without hoof it cuts 0.5mm), it is fast (takes a big bristle field), it shaves all the same everywhere (whether with or without a shoe, I think the neck for example, I do not systematically shoe).
The really nice: it is waterproof, so to clean, it's really not making head.
The least: we can not use it in charge (it's a base, not a cable), it's a shame, because the burden is relatively small (well you never know really, there is not more battery charge indicator, so it is a lottery). I take off a star for that.
Apart from that, very satisfied, to shave efficiently and quickly (eg in the morning), it is at the top.
