After roughly 2 years my Campbell hausfeld 3 gallon air compressor has been replaced. The regulator went bad, fittings where leaky causing it to work harder than normal and over heat. It was always pretty loud and now it's almost unbearable. I got the $49 3 gal pankake compressor from harbor freight for Christmas as a back up, knowing the Campbell was about to take a crap. I finally busted it out and I'm impressed with it in that it's much quieter, smoother and more efficient. We'll see how long that lasts, but for now I'm calling it a great deal.
