Superb product, indeed I have often buy mowers input range, with which they must board, board ... After a few weeks, the battery no longer want, the blades cut poorly, and finally I gave up and return to the hairdresser in order to have a clean cut and not having to shave my head several times .... I ve hesitation, and given the different bldg comments, I have invested in this product. Conclusion, I should have long ago to buy a professional product, for it is another world, perfect cut, no shoe that retracts or disengages while cutting, the battery is always at full power and suddenly I shaved in less than 5 minutes. Thank you to all who have left comments that helped to make this effective m choice. I highly recommend this product
