My experience (from my Exocet, YMMV but I doubt it):
Shopping for some replacement hubs for my Exocet. I know I can go with blueprinted and rebuilt OEM units for ~$100 per hub, but I was browsing Rock Auto and saw two brands:
WJB Bearings - $23/hub
Dura International - $25/hub
Googled both, found this link on Dura:
Dura Brake Rotor Lawsuit
OK great, so they're out. Then I googled WJB, and found their somehwat professional looking site stating they have their HQ in North America (in CA) but couldn't find anything on the web about them, good or bad.

I purchased the WJB hubs to see the quality and then compared them to a Moog unit at a local auto parts store. Guess which one I took home?
Honestly, I would be afraid to even use the WJB units. They are about half as thick as the Moog units, which is a HUGE difference when we're talking about the part that is responsible for such trivial things like holding your brakes and wheels on your car.
The bearings are also night and day. The WJB units are clearly stamped made in China, and the bearings are either plastic sealed or not sealed at all and packed with terrible grease, depending on if you're looking at the front or the back. When I bolted one to the car, it didn't even spin (at all, even pushing on it) when torqued down.
The Moog units are made in Japan, have nicely sealed bearings and are overall much better fit/finish wise. You'll also notice that the body of them doesn't taper down like the WJB units do, which is pretty clearly a cost saving measure by them. The Moog units are better in every way.
C/N: Don't buy cheap suspension parts.
