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.
Overall, my MCM experience was great! They delivered fast and as promised. Great product, great price!
