    Mixed review
    I'm a pro contractor. I'm partial to Dewalt tools, of which I have many. I have had 5 yrs experience with this particular model compressor. It works fine for my needs, and is one of the few that I can load in my truck myself. My problems with this model is that the regulator breaks about once a year. The reg is tied in with the gauges and the hose connects. This part costs in the vicinity of 100.00, of which I have bought THREE. So, I thought it time for a new one. Had this one delivered to the house, and guess which part didn't work when I fired it up??? Customer service was sympathetic, but my best option was to just just take it to the Okla City serv center. It's a good product when working.

    runs like new
    I have been buying reconditioned tools now for over a year and CPO is the best.Every tool has been like new and I have saved hundreds. This dewalt compressor works great. I have the 2.5 hp double tank and this one is better. The 2.5 is louder and runs way more. This 1.8 hp runs less and keeps up with 2 framer nail guns. I am very happy. Thanks

    Still can't use it
    It seems to run just as often as my old compressor even though it holds higher pressure. Biggest issue is I have not gotten more than one day's use as it keeps blowing regulators. It is in the dewalt shop for the second time since I got it. Will run one day and the regulator goes bad. Hope they can fix it this time and I can really try it.

    What A Great Bargain!
    This compressor is used at home for around-the-house projects and on-the-job construction. The volume and delivery rate is great for purging home irrigation systems in freeze-sensitive areas as well. At almost 80 pounds, about the weight of a sack of concrete, it may be a challenge for some to lift into the back of a pickup. I'm 65 and can manage it with my F250, even with my bad back. I especially like the tires: solid material but a bit "spongy," making the unit easy to move around without worrying about a flat. A pullout handle makes this compressor handle like a hand truck. The air connectors are easy to use, unlike some I've used. The compressor motor is relatively quiet, compared to others, even in the confines of my home shop. Pressure regulation is easy to perform and the pressure holds steady, even when 2 nailers are operating simultaneously. The poop sheet that comes with the unit recommends using a 12 AWG or better extension cord to avoid overheating the motor (a good call). I like the way this unit can regulate way down to drive low-pressure tools. I have nothing negative to say about this compressor. I'm totally impressed with it!

    The "Rolls-Royce" of small compressors!
    This unit is a lot quieter than ones I've had previously, I am a small painting contractor with one vehicle & I can carry all my equipment plus this on-board everyday. The PSI threshold is perfect for just about any tool, two can be used simultaneously. I do not believe in "buying brand names", but this price + warranty is just tooooo good to pass up! Would I recommend this item--you bet your baguettes I would!!!

    very effective, worth getting
    The compressor is still pretty loud but very effective. My friend has the porter cable version and it's a little heavier and louder and not very easy to store. Of this type of compressor out on the market now, this is one of the best ones. I think dewalt can do a little bit more on it to make it even better but over all I'm impressed with this machine.

    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.
