    Four stars because I haven't used this compressor very much since I purchased it. It is small and lightweight which is why I wanted it. It will run a small pin nailer or, if you don't rapid fire, a finish nailer. If you want a compressor that will run an air blower to clean dust off things or to run an air ratchet or die grinder, don't bother. The air delivery rate is way too slow for those type of jobs. Pressure regulator worked well and it is not overly loud. Would have liked to have rubber feet on the end of the unit so it could be stored upright to save room and not scratch the paint. I will come up with a fix for that myself!

    Dewalt Compressor
    The regulated pressure gauge is way off. In order to inflate trailer tires to 50 psi, I had to crank the dial up to 80 psi. The attached picture shows both the compressor and the air pressure gauge I used to check the regulated pressure--the separate gauge is a precision instrument, so I believe its reading. Also, for most home jobs, the 1-gal tank is a little small. I'd recommend at least double capacity now that I've had the opportunity to use this one.

    Very pleased with it for my needs
    This fit my needs perfectly for an apartment dweller. I'm 60 and have been through many larger compressors as the needs required. I needed a small, quiet, lightweight home unit to clean a/c and vac. cleaner filters and general hobby task. The build is solid quality and my 1/2 hour use so far has been very impressive. Would recommend highly for this usage.

    OK to start out, I have been in the trades for over 25 yrs. I have worked professionally in virtually every trades in residential construction. As compressors go, I could not even begin to tell you how many deferent manufacturer and types I have used. I currently own 3 different sized compressors, and this is the only one I cary with me continuously. This little thing is the best combination of size, power and performance I have ever used. If you are looking for anything under a 3-4 gal. compressor, you should give this one a really close look. No..just buy it. Limitations: it is a 1 gun compressor for finish carpentry and related work. It is not made for running pneumatic tools like impact wrenches and such. You could do maybe 1 bolt at a time. If your a homeowner/weekend worrier, this is a great all around compressor. even if your laying plywood, you could make it work, but don't expect to run an entire strip of framing nails with out stopping. So, if your only going to buy 1 compressor this could be it. The 3 things that impressed me most about this product: 1. Price: compared to other manufacturers in the size class, this tools was less expensive and out performed them. 2. Performance: They "Right Sized" the compressor. It maxes out a 125 psi, which is all I need, but the best part is that it gets there with absolutely no effort. The comparable pancake compressor on the market has a main pressure of 150 psi, but the last 30-40 psi takes for ever, because the compressor is pushing to it's limits. This little Dewalt has no problem getting to 125 even when I have 100' of hose connected to it. 3. QUIET: This is by far the quietest compressor I have EVER used. When I was shopping for compressors, there was 1 review where the guy said it was horribly loud and gave it 1 star. I'll just say that he has a VERY different expectation of what a compressor of this type should sound like. I believe he may be used to little compressors for airbrushing. I saw it being recommended for that, but I would say this compressor is not specifically designed for that use. Although I am quite sure that it could be used that way. I used to put my pancake compressor in the other room because I could not stand how loud it was. In fact many times I would not bring it into the house because I felt it was to disruptive to my customers. Now I am even a little bit proud to bring it in. In fact I feel just as proud to bring this compressor in as I do bringing my Festool tools into the house of my customers. If the size and pressure fit your need, then I have just 1 word...BUY IT...ok 2 words.

    Excellent Trim Nailer Compressor
    I am a professional cabinet installer that was looking for a compact compressor to run my trim nail guns. What sold me was the fact this unit is not only small, it only draws 2.6 amps. This was the deciding fact for me due to I need to run it off 100ft extension cord the majority of my jobs. The other was the price point. Once I received my first impressions were WOW! First was its size and weight and then how quiet it was. If you need a compact trim compressor DeWalt has the unit you need.

    Nice small quality built quiet compressor but just not enough pressure (125 psi) or volume for high demands. Fine for small jobs.

    DEWALT compressor
    The 1st one lasted a few weeks before it would not even turn on anymore. Warranty replaced it for free which was amazing but the 2nd one lasted less than a month before the on/off switch broke.
