this mower is full of good ideas: for use under water and extremely easy to clean, autonomy is excellent and at worst it can be used during the load connected to the mains. The choice of length of cut is very wide. Only downside but I have not found better so far: you really use with the shoe stuck to the skin so that the cutting height is respected ... not obvious to the neck and chin .. if we make one quickly finds himself quickly with "holes", places shaved shorter than others
