Price and performance in order

If you understand how the system works, it works pretty good crimp. I certainly had no problems. The threading is practical, you just have to insert in the correct direction in the plug. One or two failed attempts should calculate it, that you can use later as a good model on how not to do it. When inserting the threading correctly, works well and crimping the wires are securely connected to the connector. The disadvantage I find the lack of strain relief. If you want to frequently reposition the finished cable later, the plugs are probably not necessarily the right choice. For permanent connections, the lack of strain relief, however, should not be a problem.
Overall, the connector for the price are ok.
