In general, I have owned it for a year and a half, the body is slightly rubbed, but overall I am satisfied. Bought for about 14k in the online store. I did not make a 3-year warranty, but I think it is not needed)). Has some pros: 1. Powerful. Tightens any self-tapping screws, capercaillie, etc. which I had. Drills just about everything. Several times they had to mix the tile adhesive in a 16l bucket (the electricity was turned off at the facility), the full bucket was mixed at the 1st speed without crackling. 2. Compactness. Lightweight, excellent weight distribution, great in the hand. 3. The backlight is very pleasing, it completely illuminates the place where you use the tool. 3 lighting modes. The flashlight mode is very bright, sometimes in the dark it helps instead of a flashlight. 4. Battery. Charges quickly (40 min), lasts for a long time, I have 2A. H. There is a charge indicator, very convenient. 5. Cartridge. Quick release, doesn't seem to loosen yet. Metal. 6. Reliability. I fell from 3 meters - and there is nothing, it continues to work. 7. The envy of colleagues and competitors in relation to this Shurik is also good)). Its cons: 1. Radial chuck runout. Not big (about 0.5 mm at 10 cm), but not pleasant for an instrument of this class. Compared with Makita 18V, so there is none at all. 2. Noise. I don't know if it's normal or not, but it's loud. I thought a brushless motor would be quieter. 3. Reverse button. Not informative, there is no clear fixation of the switch, but probably this is a matter of habit. 4. Button. The most unpleasant thing was that when unscrewing (reverse) with the left hand in the extremely left uncomfortable position of the hand, the button is not pressed, as if it bites and does not allow to be pressed. It froze very much (especially when I somehow crawled to the place to unscrew it, and then the button jammed), and the same thing on the right side to twist something - all the rules. I found the same Shurik in the store, he has the same problem, the button on the reverse is poorly pressed with his left hand. I had to take it apart, sharpened something in the button (it turned out to be such a design feature), now I'm happy with everything.
