Simon dont waste your time. The virbration of air is what breaks some of them tight bolts free. Plus it wont jar your hand as bad. Electric will not have the vibration of a air rachet. After u tighten something down with the cordless socket u will have to go and re check it. I put my drive shaft bolts in with one and after 2 boosted launchs my drive shaft slung off. Spin your money eles wear. Thats just my 2 cents
