Professional hairdressing, I have been very disappointed by this model, the battery quickly waned (obligation to cut the hair connected to the mains), the button is off s' is blocked rapidly (seen with other mowers) you cut the hair switch back without stopping in the off position, no top cutting blades, forced to board without stopping at the same place, hair fluff in the blades when thick hair. In short, a model that is not up to it and does not do justice to the brand's reputation in the field of mowers.
