Lithium ion vs Air

the 2 best cordless 1/2" impacts money can buy:

Ingersol Rand w7150

Milwaukee 2763.

I have the milwaukee I use for changing tires and other impact duty, it works phenomenally well.

visit the garage journal for the reviews on the two...im a big fan of the milwaukee FUEL cordless tools!

air tools and cordless tools have their place, I say buy both, you wont be disappointed.
