The sheet metal screw setting is even better.

You get the speed of setting 3, but the gun cuts off the second it detects any resistance. I liked the 1/4" hex impact so much that I actually bought the basically identical 1/4" square impact for 2.5x the price. (The 2553 hex impact is the bargain. I've picked up a few of them for $50/per on FB marketplace. Screaming deal.)
