Smooth as ever.

This is the best palm sander out there. It transfers very little vibration to your hand and grips the sandpaper securely. It is built to last!

Best sander, I was going nuts thinking I would'nt find another like mine!

I had my old one for about 30 years, even my wife loves using it! Please don't stop making it!

As good as the original

I don't know how long I've had my original speed-block, but it must be at least 25 years. Although it works perfectly, I thought I'd take a chance on a new one in case the original ever failed. I'm glad I did. It works just as well and even sounds identical. Maybe this means Porter Cable will start making quality tools again.

My New Speed Bloc

My old Speed Bloc finally gave up after a little more than forty years. I was so happy to find my favorite finish sander still in production. I hope and plan to use this one for forty more. The best does cost a little more than the big box sanders.
