    I would buy this again
    It has a synthetic oil filled crankcase, which should make it last a very long time. Some reviews consider it noisy, but it's less noisy than a oil-less compressor. It is a little heavy. I call it a lug-able. The pick up time compares to my 5hp stationary compressor. Just like other Dewalt tools, this compressor shouts "Quality" when you look at it.

    No, I would not recommend this to a friend
    Not enough Pressure
    Very Loud for an oil lube. I ended up spending a bit more and got a Dewalt with more Psi and Power.

    I did the break in process. Then I went to fill w air after the 20 minutes but I left the red plug in the oil whole not the dipstick. So it popped out I stopped it immediately when it made the noise and was not to touch. Am I okay to just put the dipstick in the whole and be okay or did I ruin my compressor?
