Once installed they work great! They provide much more angle than any knuckle can provide and they spin smoothly throughout the throw. Installation can be a problem for some. I had to switch out 4 of the 4mm wide bearings for 3.5mm ones on the inner knuckles. It was also hard getting the bearings on the outer shaft but a little sanding to take off the coating made them slide right on.
