These connectors are a complete waste of time- they do not work as advertised and are poorly made. The only positive is that they ARE made of nylon so they may last longer than cheap plastic alternatives .However the cons far outweigh the pros. The Industrial and Scientific community deserve better quality products than this!
Pros
Easy to install
Cons
The audio quality may suffer compared to higher-end connectors.
I wanted nylon plugs as shown in the picture but got vinyl plugs. Not what I wanted and the amount wasn't 25. First I got 10 and after communication they sent me another 10. Still not the 25 I paid for. I will not order these again.
