I bought these for my FLSun Delta. They're not bad but need a bit of work. First, the carbon tubes are not all the same length, some varied by up to ~1mm, easily fixed but just be aware. Second, the balls are a little rough. If you want buttery smooth action, lap the balls into the magnets with a small amount of valve lapping compound (auto parts store) and then clean the ball and magnet thoroughly, then apply a small amount of a good (meaning, don't be cheap) PTFE/Teflon grease, like SuperLube. Use a good epoxy adhesive to glue the thread into the carbon. I didn't have the problem with M5 threads that others have mentioned, mine were M4 (Feb 2018)

all parts arrived in good condition and the bars are impressively light! Only issue is that they were shipped with M5 set screws that don't fit the balls or rods...

Happy with this purchase, and the quality. The threaded posts slide freely into the carbon rods, plan on using epoxy to secure them. The balls fit perfectly on the magnets, and the magnets are strong. A screw or bolt through the magnet hole doesn't seem possible, and the magnets seem to be too smooth for epoxy, plan a compression fit.
