Not sure if it is self-sharpening, lubricated with oil as instructed, but it seems to be dumber and dumber. Due to the course of the head, you mainly have to shave with the upper blade, because the lower one, probably, will only reach the beard. Its pros: Good design, light weight and small size, charges from 5v (any phone charger with USB). Li-Ion - fast charging, long discharge. Has some cons The head does not swim comfortably, you have to dodge in order to shave, you have to drive with nozzles for a very long time, as it catches little hair. Shaved hair flying in different directions.
