cute little machine
nice little portable compressor for light work. i love the handle and wheel on it for moving it. everything is great EXCEPT ONE/2 THINGS: its not for use in freezing temps. it is hard to start up. takes a big jolt of electricity so you cant have weak outlets or it will trip the breaker. ive never been able to get it running in the winter.

I was nervous after seeing two reviews but took the chance. Dewalt has always performed for me. Had two weeks now, flawless! Recharges quick, portable, works well with NO problems. Somewhat quiet, compared to my old CH. $159 at Lowes and I get a discount. Would recommend and would buy again.

Very good but I recommend to inspect the item when delivered.
Great small air compressor but disappointed about the delivery because the box was open and the tank has a dent on it. Five stars for the product 0 stars for the delivery

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 120 days.
