Fast effective way to connect my esc to my batteries in my rc car collection. Decent amount so you'll not run out anytime soon. Great product well-made.

These shaft couplings (6mm to 6mm and 5mm to 6mm) are completely worthless! The brass is so thin for the 6mm ends that the set screws will only work if there is no shaft. Once a shaft is inserted (usually the case, LOL), the set screws become useless! Cheap! Cheap! Cheap!

I'm using one of these couplers for a high-speed motor coil winding application project. Another is being used for a digital decoder. They are well balanced and robust.

The couplers were all there and even came with a couple of extra set screws!

Outer diameter too small, set screw does not thread on the 6mm end unless you grind the shaft where the set screw should land
