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.

Does the job, easy use, a bit bulky not exactly as described
Size: 12 Pairs / 24 pcs
Bare wire can be intolerable to work with. Banana plugs make a positive secure connection. These plugs are a touch bulky. Nice to not have to deal with small screws. Use as large of gauge wire as possible. The description says no unintentional disconnections. I beg to differ the bite of teeth aren’t as good as described. Used a 16 gauge pure copper speaker wire and a teenager taught me how secure the wire really is by tugging on the wire not the banana plug pulling the wire free. It does the job, it’s not the latest and greatest. If you need easy get these. If you want slim secure banana plugs buy the small screw type.
