Pros: low noise
When the first displayed an orbital drilling pattern (egg-shaped) and I couldn't fix it, I took it to a licensed repaired shop. They failed to fix it and ordered a replacement. Ryobi shipped a rebuilt. It arrived FULLY assembled in a large cardboard box with NO packing materials: the base arrived broken, the top smashed. I called Ryobi and demanded a new one in its retail box. They reluctantly agreed and sent it. Elapsed time: 6 months. After a year of very light use, it drills in an orbital pattern. The problem does not seem to be a badly mounted chuck. I'm not going to the repair shop again. I'll buy another brand.
