i'm coming from using 4.6 (dual tank) and 6 gallon (pancake) compressors.
i like how it is quiet, relatively light, and aluminum (don't have to worry about rust).
i was anxious that this little guy wouldn't be able to handle lugnuts but got a little bit of reassurance from a couple reviews. well, i'm happy to report that i used this compressor just yesterday to rotate my tires.
i used this along with a harbor fraught earthquake 1/2" impact wrench along with a 50 foot 3/8" air hose. also, my lugnuts are tightened to 75 ft lbs. the compressor kicked in at the 5 or 6th lugnut but I didn't have to stop and wait to complete the job for the wheel. the compressor would re-charge as i moved to the next wheel. YMMV with your wrench and hose (and compressor).
blowing out car air filter to clean it was a different story as the capacity is not high enough, but, i eventually got it done after waiting several iterations to re-charge.
time will tell if the rings/pistons/motor craps out, so, i will update the review if that happens.
the only hiccup i experienced was when the unit wouldn't automatically recharge when i was continusouly using an air nozzle to blow out the air filter and almost exhausted the tank. i had to turn off and on the compressor and it recharged. the unit, however, would recharge if i was a bursty in air gushes versus continuous at around 90 or so psi and would go back up to 115 or so. i'll probably read the manual to see if there is anything will help with the aforementioned issue.
i will be using this for light auto work, light carpentry stuff (nailers), and blowing out (i.e. cleaning) dust/dirt off of various things.
i would have rather gotten the dual (4.6) or 5.5 gallon tank versions but got a good price on this 2 gallon unit, plus, the aluminum versions of those units are more expensive as well.
as others have mentioned, set your expectations with this little guy and you should be fine.
