When I ordered this screw gun I was all stoked on what a great deal I got so I decide to challenge my Brother and his friend to a screwing contest!!!! We lined up his Hitachi 12V and his friends Makita 14V and went to it. We used a chunk of 4X6 and 3" deck screws. First came the speed competition. On the count of 3 we all started screwing. The results: 4-6 seconds for both of them and a whole 25 seconds for the mighty B&D. I was a little bit let down but I thought I could still take them in the stamina competition so we pulled those screws out and started in another spot. My Brother and his friend handily beat me once again on the second screw (even though the Makita had an almost dead battery). I almost had the second screw all the way in when my Brothers friend started yelling at me to stop, I looked down and smoke was flowing out of the vents on the rear of the gun. I stopped before the screw gun caught on fire but I guess you can say the Black and Decker got smoked by the competition.
