Disappointed - First off the unit is huge, it has a handle but won't stand up on its back legs,it gets hot and has no easy place to grab it to put it in the truck, it is the noiseist compressor i have ever used. The on off switch is all but hidden, the cord wrap is useless, the wheels and axel vibrete and rattle, even the stickers are falling off already.
Used it today for the first time - I use an air hammer to break out the old windows and they require a lot of air. This compressor worked well with some catch up time but hey, it's only a 4 1/2 gallon tank. Cord wrap is fairly useless, handle makes it portable, regulator worked, switch and air release are protected.
Good, But..... - The only complaint is that the outlet pressure regulator is cheap.
Rattle can construction - This air compressor will rattle out most of its bolts within a year. The Pressure regulator will fail in about a year as well, be prepared to spend a lot of maintenance money keeping this piece running.
Fine for finish nailers - This compressor is LOUD and ear protection should be worn if you work near it. The problem lies in the fact that the unit cycles at 115 psi which is lower than the hose pressure needed for rapid nailing.
Dependable and... dependable -
I've been using this compressor for about 3 months now. Nailing, stapling, and air cleaning.
The pressure, for the most part, maintains its equillibrium. What I don't particularly care for about the unit is the airflow adjustment valve. and I don't trust it for the compressor's duraction.

05 update: I noticed one reviewer griped about this tank's compressor turning on frequently while using an air wratchet or something. that's an unfair assessment. Using such tools would cause the same reaction on any tank with the same air gallon capacity.
From a homeowner - This is a great compressor. The manual says 15 Amps, but its more like a hair above that. The copper one that pumps the air into the reservoir. The cut-off pressure is not adjustable. (I definitely wouldn't want to buy a second compressor for that either. Aside from those minor inconveniences (hence the 4-stars), this is a very plug-and-playable compressor for the DIY homeowner. I made the mistake of buying one of the pancake style compressors and found it a little weak for doing the basement framing.
