Since Im using this razor, my face is bit irritated after shaving, it takes more than 3 weeks to get used to it. Another thin is, this razor takes too much time for charging and short time of use(aprox. 15 min) .Overall. it works for me only if I use it in early hours (7 or 8 am) after that, its a mess
