Well made, a solid connection.
Size: 6 Pairs / 12 pcs
I liked them. They really lock down on the speaker wire to make a firm connection. They seem well made and are easy to install. My system sounds great.

Works as intended
Size: 12 Pairs / 24 pcs
These banana plugs are quite easy to use, and securely connected my speaker cables to the receiver. They have a quality feel as well.

Tips broke in the binding post
Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs
UPDATE:
Two tips broke off when unplugging them from the binding post and are now lodged in. Inexcusable and an utterly poor product.
Solid connection in the binding post with no wobble or wiggle. They require some force to insert into the binding post, but once they're in they remain snug. I also tried removing and reinserting a few times and the connection remained solid. I've used other plugs in the past that have a softer tip and easily deform after one or two insertions. These do not have that issue.
