Useful Addition to My Workshop
I use this product for sanding curves in my woodworking projects.

The only reason I did not give this 5 Stars was because the initial tool I got was defective (one of the plastic *ugh* sprockets had teeth worn off it).

However, that being said the CPO team did a -fantastic- job of handling the return. I am definitely going to be purchasing more tools from them.

A really great addition to my shop.
Easy to change sanding drums.

I had to take it to a service center within a week after purchasing it. They did good job of reparing it. A bushing was improperly installed...

A round trip of 100 miles.

The steel table top was stained badly. It took a lot of abrasive hand rubbing to get the stains out and make it smooth. The grey base was grease spot stained , which could not be removed.
When running it seem a bit noisy, however it does work and seem to have all the accessories . I have used it once so far and it functions ok but cosmeticly it leaves much to be desired.
I realize that I purchased a recondition name brand unit ,but for the price I thought it would be much better. My mistake.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 60 days.
