Review on 🔧 IWISS Non-Insulated Open Barrel Terminal Crimp Tool - Wire Crimper for Molex, Delphi, AMP/Tyco, Harley, PC/Computer, Automotive - 24-14 AWG by Eric Rose

As stated by others, jaw alignment was disrupted from the start. This is an interesting problem because of the way the shirring arm was designed. The two jaws don't really match, they approach offset (meaning the two mating surfaces don't match properly). The two jaws are forced to align when the crimping tool is fully closed, but this causes one side of the jaws to slide over the connector before it aligns properly and can interfere with the crimp. This is really not optimal, especially with such small plugs and crimps. I will most likely look around and buy an alternative. I would put it down to poor quality. It will work, you just have to be vigilant and careful how you use it. If I had looked at this at a hardware store, I would not have bought it.
