Ive used the 12v version of this drill for years and got this as a 2nd to have a drill and driver without swapping bits all the time.This 18v has incredible power and battery life. It comes with a 2nd battery which is a must. This one would would torque out of my hand before stalling.There are 2 functional features that were better on the older drills: 1) The chuck is all metal now and a bit smaller in diameter then the old style making it harder to grasp and tighten (old style was rubber with nice nurls to grab. 2) The drill to driver switch has a small safety afety switch that has to be pushed in before you can activate the slide switch. Its a total annoyance as a simple slide switch as is on the older models would have been just fine.
