This should last a while! The PrimeCables brand has impressed me with their quality. I recently bought a Primecables Hybrid Tube Amp and am very pleased with it's performance. BTW, if you use Banana Plugs, make sure they are of a size that can accommodate 14AWG. I didn't and had to buy all new banana plugs.

I'm currently using these with 16 AWG wire. At first I thought they didn't fit properly because the screw wouldn't tighten far enough to hold the wire in - turns out stripping a bit more wire and bending it over onto itself fills the gap and makes the screw tighten down on the wire properly. I really like that the wire can come in from the base or the side since, depending on the situation, one of the options tends to work better.

Work great

High quality, easy to use, snug fit to terminals. Definitely recommend!
