Best extremey low vibration palm sander ever built.
The least vibration of any old or new palm sander. A woodworker's classic discontinued by the manufacturer after almost 50 years in production -- from porter-Cable to Rockwell and back. Had to buy one before they are all gone.Verified purchase: YesCondition: Pre-owned

My favorite finishing sander
My three stars were for this particular sander. The 330 Speed-Bloc is still my all time favorite random orbit sander. I have more sanders than I have screw drivers. I hate sanding, so I spend a lot of money to minimize the time I spend sanding. I bought my first PC 330 Speed-Bloc in 1985 and still use it. It's a little ugly, but still works like new. I have replaced the power cord and pad several times, but everything else is original, including the bearing. I overpaid for this latest sander, considering the condition. The pad was shot, the power cord was frayed and the pad posts and coupling (rubber parts) were stiff, causing the sander to vibrate more that it should. So I had to replace those parts, which added another $50 to the cost of this sander. But since this sander is no longer made and none of the competitors' offerings work as well as this one, I am content with my purchase. No slight to the seller. I paid the high price because I wanted a back up.Verified purchase: YesCondition: Pre-owned

Great Finish Sander
I have been using the 330 for years. This is a replacement sander. I did notice on first start up the sander would not stay on the work piece. It kept 'bouncing' around. This stopped after a few minutes.Verified purchase: YesCondition: New
