This thing rocks. On Saturday I installed snow tires on Kathy's car, rotated the tires on my 3/4 truck and swapped wheels on the M3 so I can sell the LTWs. That's 72 lug nuts including 32 that were torqued to 125 Ft/lbs last fall.
The Dewalt just ate it up and asked for more. It can easily remove lugs bolts when the wheels are off the ground. It's got plenty of power and makes quick work of everything I've thrown at it. When reinstalling wheels, the "rocker" trigger is nicely variable so it's easy to snug-up bolts without over torqing them.
That said I also got to use the 18v Snap-on and talk at length with a guy who owns one. As nice as the Dewalt is, the Snap-on is the best tools available. It produces well over 600 ft/lbs when removing fasteners. In fact the Snap-on is the only wrence designed specifically to remove fasteners. The Dewalt and the Milwaukee are both designed to drive-in fastners with the same power that they are removed. The Snap-on produces twice the torque when removing fasteners than when installing which is perfect for automotive applications.
So If you can part with 5-large for a cordless impact wrench, then grab the Snap-on. If your're thinking more like $300, then the Dewalt is a good choice.
Allow me to explain why most comments you read about the Singapore start are wrong... - Hi, I'm back. I had to jump in, for what it's worth, to explain why the response to the first lap crash at the Singapore GP was an even bigger clusterfu...
