Knoweasy JST Crimper and Micro Open Barrel Crimping Tool - Works on AWG28-20 (0.08-0.5mm²) JAM, Molex, Tyco, JST Terminals and Connectors for FPV, Drone Servo Medel KN-2818

I bought these for a specific project on my 3D printer but now that I can reliably make connectors I use it way more than anticipated. I mostly make JST and Molex connectors and it works great. I had to mess a few up before I found a reliable technique but now I can strip wires and make connectors super fast. Does the job.Very convenient and useful!

This is the closest thing to a factory crimp I've ever seen. Better than tools sold by companies that specialize in electrical tools. Make sure the size works for you.

The media could not be loaded. Wow these are excellent. I was a little hesitant about some of the reviews here but after revieving them I don't agree with any of the negative reviews at all. These are very nice quality. Very nicely cut and shaped teeth. They go from maller to larger in width as well. What I was most surprised about an extremely happy about was the opening spring it has on it! Somehow that is completely missed in entire description of the item and I didn't see a single reviewer mention the spring. Not having a spring is pretty much a deal breaker for me especially if you know you are going to do many crimps in one session. Having to manually open a set of pliers after every time you close it is what kills your hand and drains the strength from your grip the fastest. Now I was really second guessing myself buying these because I went into them thinking they didn't have an opening spring and I normally won't buy a set of pliers without one but these were still the best option for me at the time. When I got them I was very pleased to unlock the or the first time and they went flying open. Thank th Lord all mighty lol what a gift. The grips on these are some of the most comfortable grips I've felt on pliers and I've had all the big brands. Knipex , engineer, you name it but wow these are very comfortable to hold and even more comfortable to operate thanks in big part to the opening spring. I have a ton of crimping to do on a ton of very small jst style crimps so you can imagine how relieved I am to have that opening spring. 10/10

Nice crimp tool. Well machined parts and they work well.

I got these to do one project. Well they work so darn good I am recommending them to anyone who works with these connections. Excellent crimp quality, and accuracy small and compact and a great value for the money for sure. Will not disappoint.

I have multiple crimpers, but none of them worked properly on the very small JST-XH connectors so common in products. Although this crimper requires 2 crimps (1 for the wire, 1 for the cable crimp), it is sensitive enough to crimp properly and to not damage the wire in the process. This is a great tool addition for crimping small connectors.

I bought these crimps to help me replace the quick connects on Epiphone 5 wire pickups. These worked pretty well using the second notch on the jaws. I did have to slightly bend the larger side of the connector socket that crimps to the rubber side of the wire to get it started in the jaws.

Bought these for my husband! They seemed to work ok. I didn't have a chance yo ask him , his option on them.
