incomplete package - As someone who is new to the Air tool game, I didn't want to spend alot of money seeing how I do not use air tools regularly but wanted to try them out.To get longer service life than oil free units, This compressor is an oil lubricated unit and yet it does not come with oil! I guess thats one way they can cut costs. It also does not come with a quick connect fitting at the output end, but rather has female threads that you screw an air hose into.
I saw this compressor for 139.
The manual is not very well written at all, so take your time and read it over a couple of times!
When you get this compressor, you will have to go out and buy; 1 bottle of mobile one synthetic motor oil(10w30)for abot 5 dollars, a 1/4 inch fitting and quick connect(about 12 dollars). Now you are ready to plug in a hose and air tools.I am extremely happy with this compressor-it really isn't any noisier than other compressors in this price range-lets face it-compressors are a power tool and thus are loud!I did not find the noise that bad at all. It produces 5cfm at 40 psi, 4 cfm at 90, so it will run alot of tools besides nailers on an intermittent basis.
My total investment to get this up and running was still less than 200 dollars which is not bad for an oil lubed compressor.
Good - I too bought this compressor from Costco and it came with a finish nailer. Obviously it won't run tools that require huge volumes of air for extended periods of time.

All compressors are loud, this one is no different.

The weight is exactly what you'd expect, for a 4g compressor like this.

Compared to electric power tools, Campbell Hausfeld air tools save you both time and money. The initial cost of an air tool is significantly lower than its electrically powered counterpart, and the average life is longer. Air tools also deliver more torque and higher revolutions-per-minute than electric tools, helping you complete your jobs more quickly and effectively.

Good compressor - She doesn't need it to run air tools, basically she'll use it for airing up tires.
Sturdy, portable, cheap oil-lubricated compressor... But noisy! -

Let me start by saying that I can't live without an air compressor. Those of you who don't have one have no idea how much you'll use it and what an integral part of any household project or repair it will become when you finally have one. That being said, let me explain why I bought this particular compressor and what I think about it thus far.

Until recently, I had an 8-gallon oil-free compressor that was handed down to me from my dad after I bought him a large stationary garage unit about 6 years ago. This thing lasted about 13 years with very regular use with a few repairs over the years. This is absolutely unheard of with an oil-free compressor. In order to replace the blue tarp roof provided by FEMA with some actual shingles, I will need a compressor to power my roofing and framing nailers. Portability and reliability are important factors in order to assist with the reconstruction efforts of the community once the repairs to my home are complete.

I always try to buy tools that will last a very long time and are as reliable as possible, for obvious reasons. This is why I decided on an oil-lubricated compressor. Although I had great success with the aforementioned oil-free compressor, I do understand that this was more the exception than the rule. It is hard to find an oil-lubed compressor that is both portable and affordable., making them very difficult to get in and out of your truck/car by yourself, let alone getting them up a flight of stairs. This compressor does not come with oil, even though the instruction manual says "only use the oil that was shipped with the compressor." The other thing that you will run into is that it does not come with a coupler to connect an air hose to. Although this is very common for air tools not to come with the required fittings to connect it to a hose, there is one difference here. I have never seen a quick-disconnect air hose connector (the hose end that has the sleeve to release the connection) with male threads on it. (a brass pipe nipple for you plumbers out there)

Use:
The Campbell Hausfeld HL5501 overall seems to be a very good compressor. If you are looking into this compressor because of the reduced noise level that oil-lubed compressors are known for, then you will be disappointed. This compressor is every bit as loud as any comparable oil-free unit.

Conclusion:
I would recommend this compressor to the handy home user that wants the reliability and longevity of an oil-lube compressor, but doesn't want to spend a lot of money. I would not recommend this compressor if the noise level is a big issue, but be prepared to spend a lot more money for a belt-driven unit.
