I bought one of these to replace a Campbell-Hausfield compressor I've used for home projects over the past 20 years. My C-H was still viable, barely, but lacked some pretty basic elements that have made using it increasingly questionable (no pressure gauge, a crude output pressure regular which doubles as the tank drain, no automatic cut in/cut out). With another project coming up, I decided it was probably past time for a change and so began looking. I was very tempted by the very favorable reviews for the big brother of this one, the Porter-Cable C2002-WK, a pancake compressor that was just a bit too big for my needs, not to mention 10 pounds heavier and $60 more. The fact that Amazon had this one priced for $80 on Cyber Monday sealed the deal. It is very easy to use, although as many have noted, make sure you perform the 15 minute break-in by running it with the tank drain open before you pressure it up for the first time. The drain is a levered ball valve on the underside of the tank that is positioned so that when you lift the front of the unit to reach it, the valve opening will be on the tank's lowest point. The factory settings have the pump cut in when pressure is less than 120 psi and cut out when it reaches 135, which has worked flawlessly on my unit (there is a spring-loaded emergency pressure relief valve should the cut out fail for some reason). A knob allows you to set the output pressure level to match the pressure need of your device, although with a 1 gallon tank it can't be anything that requires a lot of air flow other than in bursts. A quick connect is pre-installed for common 1/4" NPT coupler plugs. For me the big attraction was the low profile for the 18" shelf in my garage and the low volume level (it's still a bit noisy, but well below ear plug levels; i.e., you can work along side it). I've set it up with a 30' air hose and tire inflator to have it always ready for that particular need. Otherwise, the compact form factor is well-suited for hauling it to where it's needed, and it is more than potent enough for my brad and staple guns, although a professional might prefer a unit with a bigger tank so as to drive more nails per minute.
