First impressions are that it exceeds the advertised specs- and more importantly why I bought it. The unit came securely packaged and double boxed. I mention this as a Hitachi that I had gotten from Amazon a number of years back. Amazon being Amazon handled that situation well, but it was a relief having this one pink and perfect. The Porter Cable 6 gallon that this replaced , served me reasonably well. Though the first one on that and its replacement developed leaks within a month. Should this one do the same, I will update my review. I still have the old Hitachi- and it doesn't leak a bit.
To start with, the noise from every other small compressor I've had is simply rude compared to this little gem. Not only does it run quietly, it performs well. The old PC was starting to draw more amps as it aged. This runs off a nice 5500 watt inverter, but when the 8.5 AMP cold start draw eventually turns into 12 and change, it is time to take the stress off. This one currently pulls 7.4 amps all day long. I opted for the aluminum tank as I am one of THOSE who doesn't drain his tanks as often as I should. I don't spray with it , so I'll be doing well to drain this once a week. You know what the other steel tanks looked like when they were drained. Rust. This is actually close in size to the PC as well. It nestles in the same frame as that one. Bonus.

I called right after I bought the unit. The switch will not cut on. The company never would return my phone call.
I have to tap the switch every time to make the compressor turn on still to this day.
No warranty and bad customer service. Sincerely, Jason

After one month of use I can say that I am very pleased with this compressor especially at the price I got it for here, which was $238 with tax.

It is, as advertised, ultra-quiet, even quieter than the little Senco hot dog compressors. It also draws less current when running compared to other compressors of a similar size and is quite a bit lighter than other two tank compressors. We will see how long it holds up but it seems very well built.

I do finish work and we are currently finishing the first of three large houses. This compressor is usually driving two or three brad and/or finish guns all day long and seems to easily keep up with the demand, recharging quickly enough to prevent the pressure drop that happens with other compressors when firing a lot of nails rapidly. You don't have to wait for this compressor, which is good since you often can't even hear it.

If you are a professional and looking for a new compressor for your finish crew, one that can keep up and that you don't need to hide in a closet because of the noise this is the one you should get.

First off, this thing is surprisingly quiet. Everything works great and practically no leakage. After 1 week at full pressure, there was only 1.5lb of pressure loss. There was a small amount of damage which I am not concerned about. You can run this in the house and not disturb anyone. I would recommend an auxiliary air tank though. I used the tank from the dead 20 gallon compressor this unit is replacing. Less than $8 in parts and it's a fully functional tank. I spoke with California Air Tools and they told me that this is a 70/30 motor and that I shouldn't run the compressor for more than an hour at a time so the 4 minutes it takes to fill the total 24.6 gallons doesn't worry me. Sure, it takes a little longer to get 20 gallons of air, but my ears aren't bleeding while the compressor is running.

Super quiet, but that's why I bought it. Well packaged, it survived intact as I watched the UPS man roll it out the door of the truck (yes, he rolled the square box up the aisle and was end-over-ending it down the stairs when I told him to stop and I would take it from there). At roughly 45lbs, it's not heavy, but still not light; however, definitely light enough to carry out of a truck. Would be nice to see an aluminum frame for even more weight savings. The on/off switch is not readable unless you have a clear angle as it's black on black. I simply wrote on/off with a white marker to make identification quicker, especially in low light. Because of the small capacity it took some time to fine adjust the regulator to (110psi max) without going below. Once I found it, I marked the spot as a reference. I was easily able to adjust the low limit switch to 95psi (factory appeared to be ~85psi) to ensure my nailer didn't fall below minimum.
Finally I don't get interrupted by the compressor, and the baby can still sleep when I work inside. For reference, I replaced a bostich pancake with this unit. I swear the bostich was louder than my 5hp shop compressor. This compressor is being used for nail guns only. You could fill tires and do the occasional blast of air, but capacity is lacking for any flowing air application.
