It works pretty well with standard and thin speaker wires. It makes so much easier to plug and unplug speaker wires. Color coded makes it easier for future. Banana plugs are worth. Double screws ensure wires remain securely attached. Screws are bit too tiny and had to run to the store to get one of those fine tip screw driver though.

Great Quality and Value - Perfect Connections

Size: 10 Pairs, Pattern Name: Banana Plugs

I used these Monoprice 24k gold-plated banana plugs to connect both my surround sound and desktop speakers, and they work perfectly. The connections are solid and secure, with no looseness or signal issues. They’re easy to install, look great, and offer excellent value for the price. Highly recommended!
