Very disappointed with the quality of the SportCrafters product.
The bearings on one of the drums are not pressed correctly. This causes the drum to sit too far to one side so that the end cap retention screw hits the frame and the drum will not spin. The end cap retention screw on the same drum is cross threaded and there is debris rattling around inside the roller.
The correctly pressed bearing is on the right.
Cross threaded retention screw hitting the frame...
