Ya this ones a big boy. Its heavy and updated with nice features like the battery indicator on the tool nice touch. Its heavy duty and i got a great deal on it through warehouse deals. I use all makita tools and they all last the test of time and i worked framing and drywall, stucco and i work on my house. So these babies get worked to the max. I even use the smaller hammer drill driver to cut 6" holes in the ice for fishing. And even that drill has gone through the ringer and still punchin holes. Now i will dedicate this drill for work and the other for ice fishing. Perfect.
