This has always been one of the top rated sanders but I think the P-C quality is slipping - I've had it for several yrs now and it has been flakey all along - the vibration level seems inconsistent whereby it sounds rough for a while and then evens out for a while - not sure if its just the sound and feel or if it affect the actual sanding - seems like the results are decent but no better than my old makita. More recently, the front spring clip came apart so I'm out of luck unless I use adhesive backed roll sandpaper now. Eventually I'll sell it and look for a better quality sander - maybe a dewalt. Disappointed with P-C for quite a while now. My older P-C tools are still running well though - sad to see them go down so badly. Downgraded to 2 stars.
