I really like this budget impact wrench. The headline feature for me is the variable speed control, which is an absolute must and makes using the wrench very easy. Build quality is fine: it feels well made from quality materials, and it's not stupidly loud in use. It's not particularly powerful, but it's powerful enough for most jobs you'd tackle on a car, and it's light enough to to be a nuisance. Register your wrench within a month of purchase and you'll get a 3-year warranty, which is pretty good. If you're worried about the Silverline brand being a beat cheap and nasty, I think you'll be pleasantly surprised. I'm very pleased with my purchase.
