In general, Shurik is not bad, but for the money it's generally chic. I use it when installing doors, mainly for drilling with feathers, and tightening self-tapping screws on concrete (hamos). Got pros: Lightweight, compact and powerful enough. Easy to change bits. Drilling with feathers is excellent. It twists the amoska into a brick easily. Convenient hook to hang on your pocket. Cons: Lightweight, to tighten the screw normally, you have to press hard.
