Favorite banana plugs?

@jeff333 , 

Hey, take a look at these:  Amazon.com: Viborg Silver Plated Banana Plugs, Screw Locking 4MM HiFi Speaker Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems 8PCS : Electronics

Are they possibly too cheap?  Could it be a knockoff?  Almost seems like the situation similar to the Nakamichi one's.  But, if they are legit, very cheap and basic, kind of what I am looking for.  Just curious that they are so much cheaper than the other one's I mention.  Danmar123, could you tell me specifically which one's you used?  Is it these?: Amazon.com: Viborg 4X HiFi Speaker Banana Plug Connectors, VB401G, 4MM Gold-Plated Pure Copper Dual Screws Locking Banana Connectors for Hi-end Speaker Cable, Home Theater, Audio/Video Receiver, Amplifiers : Electronics  I assume they don't actually mean bare copper, there must be a coating on it to prevent oxidation.

Thank you for the info reubent, that is probably my main concern, that they will fall out.

The best bananas I have used are from KLE Innovations

They are excellent, but they are not 'robust'! So ham fisted users should not use them.

They are one of the few plugs that actually make a discernable improvement in sound quality

@jeff333 Copper gave me the sound I was looking for. Silver was to bright.

I’ve got a set I got from Radio Shack a few years back that are perfect. Newer ones are just not as well made.
