Disappointing product. The cut is not at all accurate, it leaves plenty of stairs. So, we lost a colossal time to pass and repass the same place, without achieving a convincing result. The shoe is too big, and passages "delicate" as behind the ears are impossible. The only advantage for my taste: the battery life between charges. So I go back to my old thread model, more archaic, but much more precise and satisfying. Regarding the longevity of the device, the mower died less than a year after purchase, without misuse. Avoid so.
