Moving from manual lélectrique, the change was great. Taking excellent hand razor ergonomics is good and well studied equilibria. Wireless freedom due to but flip side, you can not go on holiday without the charging base. Famous poorly studied base, unstable and to be functional and not at all designed for travel. Good battery life (almost 2 weeks for a simple shaving) and full charge of the razor in 1 hour, which is fast. Shaving quality is good (but not exceptional) and remains below a significantly more precise manual shaving and finer. The 3 mobile shaving heads espouse relatively well facial contours but do not allow a precise shaving share their sizes. Shaving is better quality with gel (rather than dry) but it gets the big hassle when it comes clean the shaver in the small bathroom comes with. It's a crazy complexity (how can one invent something as complicated ???) and I'm still not arrived to operate heads as the elements are poorly studied and inoperable. Regarding the shaving head (for a ball 0), then there is better to take his misfortune patiently: you have an incredible time to get to a really poor result. And the mower in such a case is useless. Forget it! In short: quality shaving correct but accessory and implementation of those it covered most of the puzzles that the basic functionality that was expected.
