We ran them on our prototype shooter and they worked OK, but we replaced them with non-flanged bearings on the production shooter. They are going to be used in our 500 RPM ball lifter application. One of our mentors is a manufacturing engineer who designs factory machines for a living, and says they are good for modest RPM applications. Overall, I would classify them as "cheap" but not "junk." They were, IIRC, about $5 each instead of the $10-12 we paid for the better bearings we are using for the high-speed shaft on the shooting wheel.
