Disappointed by shaving

Very good workmanship. Operation is only possible with battery. When the shaver is connected to the mains (cable), the device does not turn on. So you are always dependent on the battery. Although the charges still fast, but everyone knows that the number of charging cycles is limited at each battery. I had been a razor from the 3 Series it. I was a bit disappointed by this because of shaving. This one is slightly better.
