Eichmann Bayonet plugs user experience

ABSOLUTELY WILL NEVER GET EICHMANN BAYONET PLUGS AGAIN. Before I recieved them, I was told to be very careful, and I heard about their reliability issue. I literally laid down on the floor, on my stomach, eye level with the speaker's binding posts, using two hands, CAREFULLY inserted the FIRST banana, and the copper sheath slid back into the plug. THE FIRST ONE I DID! That happened on three different plugs. I bent two others. OUT OF TWELVE BANANAS IN MY SYSTEM, FIVE WERE DAMMAGED. Give me a break! Yes the Eichmanns sound wonderful, I will say that. Also, once they are bent, technically they still work, but come on. Five out of twelve? I've been into audio for twenty years. I know how to connect cables.
As for someone above who said they "...switched them hundreds of times without a problem..." Yeah..sure. Sounds like a dealer to me.
I've since replaced the Eichmanns with something else.
You've been warned.

Not a dealer. Can't duplicate your experience. Yours may have been defective. Mine are still in fine shape, though I've gone to bare wire. BTW, I'm 79. Maybe you're too young to be able to handle them :-)

Five defective plugs out of twelve? You're probably right. Maybe if I bought twenty four I could finish the job. BTW, two of my friends have the Eichmanns and both reported plugs falling apart. Or, maybe I'm just too young to find the hole.

Okay, your problem was intriguing enough that I took some of mine and tried them in every banana jack I could find. In only one case -- one of those in-wall connectors -- the Eichmann was too long for the hole and didn't make a good connection. In every other case there was no problem at all, and these ones of mine have been used to death and are still totally serviceable.

Are you SURE you assembled them properly. You slide the metal part through the black plastic, then slide the blue plastic on the shaft and lock it to the blue part with a twist. I just can't figure out why this doesn't work for you unless there is something very strange about your banana jacks. Doesn't make sense. Dave

I didn't assemble anything. The US importer for DNM put them on. He raved about the Eichmanns, and rightfully so. They sound very clean and neutral. However, after I told him my complaints, he told me that he has RECEIVED MANY COMPLAINTS FROM CLIENTS ABOUT THESE BANANAS. He told me that he will no longer sell the Eichmanns, and will switch to another termination (at least that's what he said).
Now, with all due respect Dave, maybe you received some wonder plugs because you are THE ONLY PERSON I have come across that had no issues. I wish I didn't have any either. Like I said, they sound wonderful.
I will say this: Although the Eichmanns have PERFORMED incredibly, their ease of use and reliability have been nothing but a dissapointment due to their shody and radioshack quality craftmenship. At this price I expect Eichmann to engineer something a little better.
