DeWalt DW421
My DeWalt DW421 orbital sander worked fine at first, but did not survive much use. I would consider it dangerous when the pad begins to spin at the RPM of the motor. I would classify it as a short-life and high maintenance machine and would suggest purchasing a different brand.

I have been using my DW421 for many years, it is the best orbital I have ever had. I am a professional cabinetmaker. I have had to replace the dustcover/brake piece in order to keep it from spinning out of control.
