I bought Shurik to work at a construction site at home. I was afraid that it would not pull, but the reviews and the price bribed. I bought then in the day for 8400. Faithfully serves me for the 2nd year. During this time, we made a facing repair of one house with him. (Sheathing with slate with a twist of 25 black self-tapping screws, into guides) And they built a box with the roof of the second house (10x10m) If you select bits for self-tapping screws, then there are no problems with power at all. For me, it’s more likely even an excess, because at the beginning, out of habit, I almost dislocated my arm a couple of times. =) But this is out of habit, just before that there was a cheap interskol for 4,000. And the difference between them is just cosmic. =) To me, he's a good kid who can handle most repair tasks if you look after him and work carefully, although this probably applies to any tool. =))
