Bought to replace her sister who passed away after 6 years of good and loyal service. I hesitated for the new model no longer requiring the replacement of the head but I stayed the same because I was still ahead heads and I know his qualities at work. The downsides: the price of cutting heads to completely replace the grid when only loose about once a year ... to do every week until a laser system developed for the body and face easily price reasonable ... Positives: ingrown hairs under the skin to regrow are very rare, as well as small wounds, unlike depilatory creams, razors or blades other methods tried before ... I highly recommend it to those who do not like hair or who want a torso or a low net belly ... Contrary to what is stated, also suitable for the face when the hair is a little long for a conventional electric shaver . Eliminates most or cantankerous hair before passing the razor ad hoc, time saving.
