I had used them in the past, and their primary line of portable construction compressors originated at my request, and was prototyped in our own shop a long time ago, around the late 70's. But it was not deemed feasible for them to be cost effective making a whole new pump series from scratch. So they found a factory overseas who had a head start on the same idea, and got it tweaked into JC10 fashion. But equivalent units are being imported and sold under several different brand names here in the US. They're made in China. Makita compressors are made in Taiwan, but have had quality control issues due to lack of individual testing prior to shipment. Rol Air pressure tests every single compressor they themselves make. This can have unintended consequences. I once had a furious phone call from a contractor way up at Lake Tahoe four hours from here, who complained that his new Rol Air wouldn't start when he plugged it in and flipped on the switch. I thought about it a moment, then asked him to check the tank gauge. Sure enough, it still held 120PSI from the factory pressure test, so wasn't supposed to go on until some air was let out. That placated him. But they don't pressure-test import units here. So then it just becomes a matter of statistical warranty issues. The only problem I've ever had with JC-10's is a couple of them had a grease clog in a little odd solenoid valve, which can be user corrected via phone call instructions to the Rol Air service dept. My own Service Dept recently closed due to all the old-timer retirements, or sadly,deaths; but at least they're willing to truck things down the freeway on regular lumber delivery runs to the Makita Service Center in Hayward, which does repair other brands than their own. In the meantime, I've done some repairs in my own shop for neighbor contractors, but certainly don't intend to expand that kind of favor. I generally get paid back in other useful tools, horse-trade style.
