Great plugs and amazing value for the money. Easy to use and tighten and the screw cover works wonderfully. Even comes with a couple extra screws in case you lose one. The sound is better than what I had and I used 14 gauge wire. Plugs were perfect, not too tight at all. I could see having to push for new posts but they are snug and didn't take too much force to put in. 10/10
