Wire your own CAT5e network cables using these RJ-45 cable ends.
Almost 100% fail. Only two point, not 3 like described. So poor that connections foldover inside of plug causing it to short. Had to go to hardware store to buy replacments on a service call. Those worked just fine. MCM connectors went in garbage.
I have been dealing with MCM for over 30 years now. If I didn't like the service I'd would have found a different supplier 30 years ago. For most of my needs they are the 1st stop on my shopping list.
