The wrench triggers even screws that can not aufbekommt manually and extension. So be careful when tightening the screws !!! A very good resource when annoying change of winter / summer tires. Working for shortened by more than half. A friend has bought on my Note also Hesselink 230V electric impact wrench PIW-1000 and is excited. No comparison to the cordless screwdrivers toy! Full marks from me !!
