Review on Uxcell Coupling L20XD12 Coupler Connector Power Transmission Products : Couplings, Collars & Universal Joiners by Charles Collier

Well made and good looking but I don't know anyone else, the ones I have are pretty bad. Uxcell is generally pretty good and usually worth a little extra, but 3 out of 4 of these are too many and I've tried loosening, twisting and tightening them a few times but it didn't help. I knocked them to the side, I'm not talking about that, that's all the clutch running out of circulation and clearly visible as it spins. Maybe they didn't work well or something, I don't know, but I'm very disappointed. I'm sorry but I don't recommend it.
