Eastwood 1/2-Inch Twin Hammer Super Mini Air Impact Wrench
Product Review (submitted on May 20, 2013):
I had hoped it would be a stronger impact with the twin hammers, but I have a 3/8 impact that hits harder. It will not even break loose bolts torqued to 190 ft/lb. I like the size but I will probably not get much use out of it due to it's lack of power.
