I agree that the Ingersol are some of the very best. If the day comes when I am doing car work for a living (and given the state of the company I work for that day may not be too far off) I will replace my air wrench set with Ingersols as my cheap ones wear out. For my occasional use, the cheap ones are hanging in there okay.

The fact that I lube them whenever I use them doesn't hurt anything either.

Have a great day,
