Query: Big Upgrade

Upgraded from a Black and Decker 18 volt. I have been using it around the house for DIY projects for the past 4 months. Drill did get hot and started to smell as though the motor was burning when trying to drive some 4 in. lag screws. I gave it rest and was able to finish. No problems since then. Good overall power and speed, quick battery recharges. I would recommend the drill to others looking for a cordless with decent torque.
