Your review: I am happy with the procuct I got. My only dissapointment is that I REALLY wanted a 25,000 RPM tool, which is what this is advertised as on the website. when I received my five grinders they were all 20,000 RPM ( FP-759R-2 same part#). When polishing aerospace aluminum you need the max. RPM posiible, it makes a huge difference. Had I known this tool was a 20,000 RPM model I would have never purchased it.
