The first part of this review is for everyone, the longer parts are for those new to compressor buying.This compressor is perfect for light duty indoor applications. I used it for a 16 guage 2.5" straight finish baseboards to cover 1700 square feet, for an 18 guage 2" finish brad nail gun, a tire inflation tip, and an air sprayer nozzle. It is quiet and worked flawlessly for these tasks. I am not afraid of buying a compressor that needs to be oiled periodically, but it seems that most of the newer light duty compressors are oil free like this one. For the price and functionality this was the best compressor I was able to find, so I will adapt to owning an oil free unit. The general rule for oil less compressors is that if you want the device to last, you will try and limit the run time to half duty; meaning that if you are working on nailing baseboards for 20 minutes try to limit the time the compressor motor runs to 10 minutes. This unit does help you out by cycling itself on and off. If you are experienced with buying compressors than I conclude by saying this is yet another solid product by Dewalt, the price is fair, the unit is quiet as advertised, and well built with job-site protection and functionality incorporated into the design. If your new to compressor shopping than keep reading and I will break down the process for you.You can go crazy trying to figure out what you need from a compressor if your new to using pneumatic tools, but you've probably also figured out that pneumatic tools are often superior and less expensive than their electric or gas powered competition. In a perfect world people would just accept that oiling a compressor is much easier and less expensive than buying a new one, in which case nearly every compressor would need to be oiled. In reality, most of the lighter duty compressors are oil free, whereas most of the medium to heavy duty compressors need to be maintained and oiled. As a general rule you will need a medium to heavy duty compressor with a large gallon reserve for continuous use tools, and a light to medium duty compressor with a smaller tank (Portability) for intermittent use tools. If your going into a business that requires multiple pneumatic tools being used simultaneously or high air pressure usage tools such as jackhammers or paint sprayers, you should probably be shopping elsewhere or waiting until you get that contractors license to buy a professional level compressor for over $1000. If you are a one person show or a renovating couple than you should be matching the compressor you buy to the needs of the specific tools you will be using. So you can look at the psi rating of the tools you are interested in and the psi rating of the tank, and finally the gallon/ liter holding capacity of the tank. This may seem confusing and like a lot of figuring, so I'll try to simplify with an example and leave the math out. The specifications of this unit are as follows: 3.0 SCFM delivered at 90 PSI pump, 2.5 gallon tank and 200 max PSI. The psi range of my 2.5" 16 guage straight finish nail gun which I use primarily for baseboards is 100 to 115psi. When installing baseboards in a room at a quick pace I don't have to stop often due to pressure dropping, but I would want at least a 4 gallon tank if another person wanted to use the second air output coupler to run simultaneously. If I wanted to use my pneumatic paint sprayer that requires on;y 50-60 psi I would want at least a 15 gallon tank. The difference is that the gun uses 115 psi intermittently while the paint sprayer uses 60 psi of air continuously creating a much greater demand for air volume.My advice is to buy this if you want a quiet, reliable, portable compressor for non continuous pneumatic tools. If you need a bigger tank you have no choice but to sacrifice the portability, you have to have the tank and compressor motor that meets the needs of your tool. If you can wait for the extra power but still want it someday, wait until you need the exterior of a house or building painted and save yourself money and wind up with a professional compressor. Hire a painter to do the pain in the arse detail painting on the eaves, around the chimney, wood trim shutters, etc...After the painter finishes ask him if you can use his painting discount to get some more paint for touch ups and if the adjoining areas need some due to paint drips (Never met a painter who has said no to this, since it means you might just fix his booboos instead of calling him back as you find them). The money you save on paint combined with the money you save on spraying the easy flat parts of your house will more than pay for a compressor, a new ladder with all the gadgets like levelers and push offs, and still have some more for your pocket! Hope this review helps!
