I would reccomend this to someone unless they are trying to push more than 600-700 watts. Reason being is that I was pushing about 800 watts to my sub through this terminal and the terminal melted.

I got this for my last box I built. I needed terminals and didn't want to use bolt terminals on it so I got this. I gave it a 3 for ease of use because the knobs you turn kinda stick and make it hard to open and close.

These are working fine for me. They are pretty easy to install in a custom speaker. Being relatively thin plastic, they may not do anything for sound dampening; however, I am not aware of any better alternatives. They look decent - not a "high end" look though.

Not super good quality but they get the job done, and add that nice final touch to the box you are building.

Definitely not what I would call a "High Quality" item.
The Plastic feels sort of thin and the plastic finger knobs feel kinda chintzy. But it gets the job done. Punched a hole with the hole saw, 2-5/8" I think and it was a perfectly SNUG fit. Probably can't get it out without destroying it. definitely worthy of my mediocre system.
Pleased
