I have had this unit for over six years and I could not be more pleased. I have used it in every way you can imagine, including spraying several hundred feet of interior baseboard and trim, running five different nail guns from small brads to large framing nails with never a problem. It is invaluable as an aid in cleaning up the shop or even blowing out dust from my automobiles. The only problem I ever had was due to my failure to read the directions before trying to work on a switch (after paying for the factory rep to install a new one, I found the reset button! I know, dumb!) Highly recommend this unit.
