I am an amateur and I bought it a year ago for home repair work. I used it on bricks and concrete. Within two months of light use, it wore out the carbon brushes. I went to an electrical tool repair shop near me, but they didn't have any because they were smaller in size compared to similar ones from other manufacturers. I found them by ordering from the store where I bought it, and then it started tripping the safety switch (impossible to use). I fixed it and cleaned the contact points with Electroclean chemical. It worked for some small jobs with lots of sparks until it started tripping the safety switch again, and now I have it in its case and I use my neighbor's Makita. Of course, I will take the roads again to repair it whenever I have time. Construction-wise, it is not well-made in the electrical part and now I am suffering, what a pity.

Purchase value for money and much more than what they say that you get what you pay for, reliable tool, powerful and perfect for amateur and professional use.
