Although this drill is compact and works OK for lightduty drilling/screwdriving, it has several drawbacks. Many a coworker has picked mine upto use it, and then stand it on the battery only to find a big dent or scratch in a finished floor from the drill falling forward. Ive owned mine for 2 and1/2 years and the batteries are so weak I can stop the drill with my bare hands.Never did have enough power to drive Tapcons.
