I've been using the grinder for a long time. Already 5 years old. Not very often, as it was taken for home use, BUT nonetheless. A VERY BIG PLUS for me: this shurik lifts a passenger car with a rhombic jack through an adapter with a head of 17 in a matter of seconds, which greatly facilitates the process of seasonal wheel replacement. He ripped off the nuts on the wheels, lifted the wheelbarrow with a shurik, finally unscrewed the wheel nuts with the same shurik, threw the wheel over, tightened all the nuts with a shurik, lowered the car with it, then tightened the nuts with a crank. Yes, a wrench is much better suited for these purposes, but if this is not available, then you can adapt the Shurik to make your work easier. Great tool for your money!
