"These plugs are of good quality, well made, and good value for money. The nickel plated brass build make them far superior to the aluminium plugs on the market. They assemble well and hold the cable firmly in place, making good contact, with the cable, to allow continuity of signal. Its easy to tighten up by hand without the use of force with pliars like similar on the market. And if you clumbsy enough to drop them, their shiny finish allows you to find them easily."
