Ordered 4 arms. 3 of the 4 were flawless. Grabbed on tight to the servo splines and offered 0 slop. One of the arms had an issue with the pinch bolt hole and 1/2 of the threads were missing. I cut down a longer bolt and managed to get it to grab. All in all... great for the cost!

The pinch bolt stripped out the threads, so I had to drill out the threads and run the bolt all the way through and put a nut on it in order to be able to use them. Looks like they used good quality aluminum though.
