Review on 🔧 IWISS Mini Micro Open Barrel Crimping Tools for AWG28-20 JAM, Molex, Tyco, JST Connectors used for FPV, Drone Servo by John Langdon

Mainly used for JST-XH connectors, I used it for smaller connectors. First I bought a ratchet that just cut the ends of the wires and couldn't compress properly. It took a little testing to get it working properly, now it can create a connector in a few minutes. Usage Tip: Detach the pin from the lanyard and insert it into the corresponding hole of the jaw first, then close the jaw to hold it. I'm right-handed, so I use my right hand, the pen opens on the left. On the left is a pre-stripped wire ready to be inserted into the pen. Run it where the insulation comes out of the first set of ferrules and crimp immediately. Then move the combination to the next larger hole and repeat for the insulation. I get creams that look factory made. Without hesitation, as soon as this wire passes the first set of wings, crimp the key. And for small JSTs, you have to strip a very small piece of wire. The ratchet wasn't that comfortable to use, always stuck in one position or another, and I couldn't feel the crimping action. Pins are always broken. The little ones don't require a lot of force and don't need a lot of leverage to crimp. This is almost perfect for this type of use. The one I have seems to be well made, I've been using it for a few years now. I don't know how many thermistor, heater and fan connectors have been replaced on 3D printers.
