Review on Powerful 12V DC Electric Impact Wrench Kit - Wagan Mighty Impact Wrench With 1/2 Inch Drive And 271 Ft-Lbs Torque, Including Sockets And Carry Case For Tire Repair Tools by Nathan Jankowski

It works great and has a nice little led light for nighttime. I don’t know if it’s just me but every flat I have happens at the worst time , in the rain or snow or on a busy highway and replace your factory car jack because they are terrible and tip over is very easy to doThe only thing I dislike is the impact smudges the lug nuts a hair.but you can replace your factory soft steel with Mcguard nuts and eliminate that.All in all I love changing a tire in 5 minutes with this as opposed to a manual cruddy it came with the car knuckle busting wrench .this impact works great runs on the cigarette lighter and comes in a nice neat case that fits in my spare tire compartmentlike I said this takes lugs off quick.
