Rated 5 out of 5 by Contractor Tested We have run this little girl everyday for several hours at a time.It sits out In the weather on back of the work truck.I have pushed,pulled and dragged this machine through all kinds of terrain.Very satisfied and will buy the Identical if we ever ruin this one November 19, 2013
Rated 5 out of 5 by Good compressor...for the price I'm a contractor. I've been looking at compressors for a while. I almost bought the bigger 15 gal compressor. But now, I'm glad I didn't. This thing really pumps up fast! It isn't on long and you are ready to go. It keeps up with a framing nail gun all day without a hitch. I really like the wheels and portability. Weight is easy to manage for me. Perfect for what I need. I also have a pancake compressor by porter-cable. It has been a good compressor, but it strains more to keep up with my framing nail gun. For a job-site contractor, this is no sweat for this Dewalt compressor. June 12, 2014
Rated 5 out of 5 by Has What Is Needed At 200 PSI Tank Pressure And 150 PSI Coming Out, Plus Being So Portable. This Is The One To Choose, Not So Heavy You Need Two People To Load Or Unload, For Me It Is Easy In Or Out Of My Vehicles , Extendable Handle Is Just Like Toting Suitcase Around, Plus Dewalt Brand Seems To Always Be A Winner !!!!!!!!

Rated 5 out of 5 by Workhorse I have owned this compressor for 5+ years and I love it. The telescoping handle and large pneumatic wheels make it very easy to move around the job. It holds plenty of air and recovers quickly. I do lots of high end finish and framing work and this compressor has no problem running multiple guns all day long. In five years all I have had to do is change the air filter and replace one of the pressure gauges. March 2, 2013
Rated 5 out of 5 by Excellent Compressor, maybe one minor flaw, maybe Superior Compressor for its size. Very quiet, quick to re-charge and stable on semi-rough ground. I worry a little about the line between the tank and the compressor. With the compressor in the transport position (upright) the tank inlet is very close to the bottom. Water could easily flow down through the hose to the compressor. And, the tank bleeder can't be accessed with the compressor in the "work" position which is laying down. A very minor concern for a great product, yet a concern. May 6, 2014
