For the price I can’t complain about it. It’s machined aluminum and molded hard rubber. Virtually there are no plays between mating.

I used this to replace stepper connections on my CNC for NEMA 23 steppers. The last ones I used were the spiral cut connectors and they broke. The hard duro pad is a good buffer for the load shocks and seems to be working very well.

For the price, these things are awesome! I drilled and tapped mine for a 8/32 set screw. Looking for coupler
