1) Noisy compressor,
2) Gun does not warn user when it runs out of nails,
3) Should have provided 2-1/2" nails, rather than the 2" nails,
4) Compressor's auto on/off lever can dislodge from the switch assembly when the lever is pushed/pulled at the wrong angle,
5) Must order the free black coloured trigger separately,
6) The gun will at the odd time spall the MDF moulding surface at the nail's point of entry (which means more caulking).

I have owned this compressor for 4+ years now and am still completely satisfied. I used a hand held, air chisel to break up the mortar joints. The compressor was operating at 100% duty cycle for 10-15 minutes at a stretch, but couldn't quite keep up with continuous use of the air chisel. As an last ditch experiment, I bought a 10 gal portable air storage tank, some extra quick disconnect fittings and rigged up a reserve tank in parallel with the 4 gallon PC tank. (yes, I am an engineer) My thinking was that I would run the crap out of my little PC and if it bit the dust, that was my excuse to buy a new compressor. I am amazed to say the PC compressor ran flawlessly for the entire chimney demo and still works fine today.
Great machine - 8 Oct 02

I read every review I can find on a tool before buying and did so in this case. The problem was, there were a couple `for' and a couple `against' this compressor which didn't help in the decision process (usually there's enough positive or negative comments to aid in making a decision). If you want to ensure you don't have this problem, buy a compressor with a cage around it. Heck what do you want from a COMPRESSOR!

- Plenty of air to shoot my 15ga nails and recovery time on the tank is VERY quick.
Great Little Air Squeezer!!! - This little Porter Cable compressor is all (and more) that I expected it to be. The output should be more than adequate for my needs to run an air ratchet, blow nozzle, hand sandblaster and pressurize a small auxilliary portable tank.

Even with these drawbacks its a great little compressor for finish carpentry.

Looking at the other brands of portable compressors I really like how well this one is built.
Porter Cable Compressor Review - My compressor arrived about 7 days after I placed my order. Keep in mind that your compressor does'nt include a hose, fittings, or a filter which is a good idea to extend the life of your air tools and a must to spray paint, so these items must be purchased seperatly. It's not too loud, it can fill up fairly quick, and most of all it provided plenty of power for what I was using it for, even when using a 100 foot extension cord.
Great General Purpose Portable Compressor - I bought this compressor to run nail guns, air sand and spray paint. It is also handy to limit the pressure to safe levels for your various air tools. Shut it off, close the valve and turn it back on; you're ready for action! The unit really is portable, especially with the well balanced carry handle protruding from the top. It is not as loud as large upright compressors, but it does make a fair amount of noise, although not as much as I expected. I use it with a Souix air sander and it does run longer when I am working. If you take on a tractor trailer, get a bigger compressor.
Darn Good Little Compressor - Short and sweet - this compressor delivers on its promises - it is easy to use, easy to break-in, easy to maintain, and you can't beat the duel air hose inlets. I have found both of the built in pressure gauges to be accurate, and the oil-free motor is quieter than other compressors I have used (although it still makes a good bit of noise). To me, that's portable - I can understand how that would not be the case with everyone, but my experience leads me to believe that this compressor has a very good weight-to-horsepower-to-air storage capacity ratio.
Great little air compressor - This air compressor is great! This unit is fairly quiet, compact, light enough to be toted around if needed, no oil needed and very powerful. This unit replaced a 12 year old 15 gallons, 2 hp, craftsman rolling air compressor and all I can say is that I wish I purchased this unit sooner. I like the portable size too, it doesn't take up too much room. When comparing the 2 units the Porter Cable is definitely stronger, the only difference being that when you are running any tools the compressor is running almost non stop compared to a unit with a larger tank that does not have to refill as fast. I consider this a plus though, because I always drain the tank after each use and it does not take as long to release all the air. At this price range there are many choices out there for anyone looking for a compact air compressor but when you start to compare CFM ratings @ 90 PSI this one has the highest ratings.
Better than the pancake model - I've used the smaller Porter-Cable pancake compressor for about 2 years. The only thing I don't think is an improvement is the knob for adjusting air pressure.

This time I installed the compressor with the air hose reel from Amazon mounted right beside it on the floor. If you get the reel, you'll probably need to make a trip to the local hardware store for an interconnecting piece to connect the reel to the compressor. I now use the pancake style as the portable one (I agree, this one's too heavy).
