"Not too much you can say about CoAx plugs but these ones are pretty good.
Very reasonable for the price, metal construction and plenty in the pack so you can have plenty for the toolbox.
One thing that I felt that it lacked was a retaining screw for the inner core. Unless you tightened the clamp all the way, the collett doesn't grip the cable correctly and on my first go i found the cable moving within the plug. Went back and retightened everything and it was fine but a retaining screw would have helped.
All in all, can't really complain. They were built nicely and they did the job without costing too much."
