The build quality of the machine is not that impressive, it has that cheap plastic look that you expect from knockoff chinese products, however, the machine does most certainly work. Cut through my wall like it was butter. The only thing I was really dissapointed by was that there was no way to attach a drill bit to make a pilot hole so I needed to use a different drill to make the pilot hole before switching to this one to finish the job. Overall, considering the price, I WOULD recommend it. I'm not sure how many holes you'd drill with it before it gives up but at this price a couple of holes should be enough to pay for it.
