I held off buying any cordless tools for years. I have always used them at work (construction trades), since the contractor supplies the power tools I have used pretty much all brands. I finally broke down and bought this kit for home use. I used the sawzall for cutting treated 4x4's with no problem. The hammer drill and impact worked excellent for predrilling and running 6 inch lag screws. Don't get me wrong I still have corded tools (all heavy duty 15 amp), but it was nice to not have to drag a cord around. I was convinced from the beatings we put them through at work that Dewalt would not let me down.
