This thing works great but I can see that the build quality is a bit subpar. The power switch is flimsy and loose in it;s setting. It feels like it's about to break. It also has a Rpm surge problem at lower speeds. But I've been drilling super clean holes in 1/2" steel quickly and with no chatter so it's doing what I need it to do. And for this price I could burn through 4 of these for the price of most name brand drills. Well worth the price.
