If it ain't broke, don't fix it is an oft repeated maxim that captures the truth of the Porter Cable 330 1/4 sheet speed-block sander perfectly. The Porter Cable 330 is often stated by sander users as the best square quarter sheet sander on the market, which is a claim that can not be refuted nor confirmed without first experiencing the difference in design; specifically, the 14,000 orbits per minute pad speed with aggressive 5/64" orbit. Lower than normal vibration, correlating into less hand fatigue, is only part of the 330's success, because it also is outstandingly quiet.

Richard, from Dunnellon, Florida bought the 330 Speed-Bloc Quarter-Sheet Finishing Sander. Here's what was said about it:

This Porter Cable 330 block sander is the smoothest sander I have ever used. This is the 3rd one I own, the first on bought back in the 80s and still is running. I use these on odd shapes, as I am a wood turner. The stick-it pads are very convenient, just rip off a piece place it on the pad and you are ready to go.
