I love Ingersoll's impacts. I have a range of sizes from 1" to 1/4" and use all of them daily. The 1/2" I've had the longest for 5 years, and have yet to see or feel any performance issues. As with the 1/2", with the 3/8", I have yet to hear the impact working because they are so quiet!
Of course I'm exaggerating, you can hear them working, it's just at 84 DB, these are waaaay more quiet than all of the other brand impacts. I have been able to hear and keep conversations while in use, and they have the same breaking torque as other comparable impacts! With a quality impact that performs the same and is quieter, you won't catch me with any other brand. You also won't catch me saying "huh?" A lot either as my hearing won't be as bad as with the daily use with other loud brands. 5/5 Ingersoll fanboy for life.
