It's comparable to the Milwaukee model in most ways with a brushless motor and variable speed trigger, and the truth is, you can't go wrong with either one... Amazon's customers are just as satisfied with this model -- it's got 4.9 stars out of five with over 7,000 ratings and it's the best-selling battery powered impact wrench on the site.
