Rated 4.5 out of 5 by 44 reviewers.
Rated 5.0 out of 5.0 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 5.0 out of 5.0 by Well worth the price Had one of these compressors in the past and it was stolen, left my garage door open, Stupid me. The price may be a bit much but with the 200 psi and 4.5 gallon tank you will be free to use just about any air tool you can throw at it. I am a DIYer and do most of the remodeling of my house. I use it for all my nail guns, framing and finishing and also for bicycle tires. Allot quieter than the previous one I owned. The wheels seem to be a bit cheaper though. The last ones were rubber and the ones on the new one seem like they are plastic based. I like that there is very little to do to it when you take it out of the box. Fill the tires to 32psi and you are ready for action. Pretty much plug and play. I would recommend this to anyone who does allot of projects at home. Cant say anything about the pro users. Easy to move around and tucks away nicely in the garage. I chain it up now, LOL. Get it delivered to the store and pick it up. Saves shipping cost and it's not just dumped on your porch for someone to take if you are not home. May 25, 2015
Rated 5.0 out of 5.0 by Great and reliable Use this with my staple gun. Has been very reliable and keeps up the pressure. All of the necessary control are very accessible. May 27, 2015
Rated 5.0 out of 5.0 by Great compressor! Quality consistent with DeWalt standards. Easily transported and operated. May 15, 2015
Rated 5.0 out of 5.0 by Blew me away!! I bought this compressor for my husband for a number of reasons. One we needed a compressor of at least 3 gallons, so we could use it for general household use, but also so we could use it for air tools. And as for dewalt tools in my past experience with the other tools I own I find their products to be high quality and a brand I can trust. I didn't want a machine that was huge as currently we're in a smaller garage (a one car) so we don't have a lot of space and we already have so much stuff crammed in there, but also didn't want to limit ourselves for basic need and also being able to move it around and use it in different places around the house and garage if need be. And even with us soon moving to a larger house with a much larger garage space, its compact size doesn't take away any benefits that a different machine might give me. This compressor so far works great, its easy for me to move, and use if I need to (I'm only 5'3 and about 130 lbs) and does stands up to my expectations. It might be small, but it sure doesn't fall short. My sister had a smaller version of the same brand similar build, she was given it by the company she was working for doing air brush tattoo's and they had no complains and my dad actually uses it more than his larger one while working on his basement because its just so convenient and easy to use when working on projects that you aren't able to just do in your garage. I could imagine that it would make the life on a contractor much easier or someone who's trying to do work inside their house. Its a bit too heavy to pick up and carry at least for me, but with the handle and the wheels its much easier to maneuver. May 17, 2015
Rated 5.0 out of 5.0 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 1.0 out of 5.0 by Not a long term tool I'm a small contractor, used to buy a lot of Dewalt tools. After buying the first compressor it last for almost a year, then the belt broke. I replaced it, a month later it broke again. I loved the wheels and portability so bought a new one, after two months the bolts on the compressor head blew off. To repair would involved taking the head off, drilling out the broken bolts and replacing. On both models there was a constant problem where in cold weather one of the relief valves would stick and it would hiss all day. I used it for trim and framing guns, it wasn't unusual for me to be running two guns. After two compressors in fourteen months, I purchased a competitor's product. Strongly recommend staying away from this one. September 5, 2014
Rated 5.0 out of 5.0 by buying second one after 5 years of daily use. I’m buying a replacement tonight for my old one that finally dead today. It was a real good machine (not perfect but real good). Year 3 it needed a pressure gauge $20 and ten min. Year 4 it needed a tire $25 and 30 min. Year 5 the pressure regulator went out so I used a inline one that I had around the shop. About two months later the head broke on the compressor pump. I have used this compressor a lot and it has held up better then some of my more expensive ones I’ve had in past. April 19, 2010
