Xiaomi Enchen BlackStone 3D Electric Shaver.
Nice item. Very lightweight and sharp. It is worth the price paid, although I have expected a little bit more for the three razor blades, since they are double. In all the cases it is easy to use and hope it lasts long. The delivery time was fantastic : - less than two weeks. It is the quickest delivery as ever. Congratulations to Seller. By the way, the instructions manual is only in Chinese, what is not so good.
