I've read all about the GX compressor failures, but so far, with six under my belt and not a single failure, it's hard for me to imagine. I'm the "compressor guy" for a few friends. I have 3 CS2's for my own use and sold 3 other GX compressors for friends. Not one that I sold is what I would call "well cared for" and no failures yet. I keep my three serviced with fresh lube every six months or so. If you don't fill large cylinders, then these are the best. I would never choose a shoebox over a GX. Unless you somehow scuff a cyl in the GX, they're easily rebuild able, and even a new cyl is only $58.
I read on FB a guy says he bought 4 GX 's and they all failed in the first 30 days, but there seems a dead fish smell to the story. The statistics are hard to believe. Supposedly he kept the 4th non working one past it's return window. Who does that on the fourth failure!
I use at least one of mine daily, and more than one normally. I only fill guns with the largest having 480cc cyl. and lots of fills from empty, so they get used a lot when rebuilding guns.
