Review on Dynabrade X52 Dynorbital Extreme Power Disc Sanders by Brandon Peters

We are very happy with this sander. We use in an industrial workshop and have always been happy with Dynabrade grinders. This one seems a bit more powerful. After some use, my only issue is that the throttle doesn't seem to close quite firmly when it's off. A small whistle always sounds when there is air and the accelerator pedal is not pressed. I think it's just that.
