I like the new brushless model. I had an earlier 20v model and it lasted three years under heavy use. As this one got tired and worn out I needed a replacement so I grabbed this one. I love all of their brushless tools. This new brushless model has the same features as the previous model but with many improvements. I love that it has a belt clip for stair work. The 20 V hammer drill is practical for quick work, saves time laying cables and looking for the nearest socket. I will definitely buy it again when the time comes and I recommend this hammer drill to anyone looking for a small compact yet powerful drill.
