Three were a couple of mis-machined pieces, which is par for the course sometimes, but all the rest worked great, and it had all the necessary lock washers and nuts to install them.

I completed installation on all of our cable lines a few months back. All connected devices are performing great and they are protected.

A nice adapter however use care as they have a long threaded section that could bottom out in your device causing damage. I made a "donut" spacer to keep mine from being inserted too far.
