Great option for home use. Not for professional use. The battery is smaller in capacity, but in fact, enough for home use. The bits in the kit seem to be quite good (although the furniture maker said the quality is mediocre). The battery is holding up well. With this Shurik completed repairs and fully works out his money. The shock mode is actually pampering and does not help in any way. So, for home use only, screw a dozen other self-tapping screws and drill holes in a not very solid wall. In general, I expected more from the xiaomi product.
