PEBA Crimping Tool JST Connector kit, 20 Types JST-XH/JST-SM 2.5mm Connectors kit, Crimper Tool AWG32-20 for 3.0mm, 2.54mm, 2.5mm, 2.0mm Pitch JST(XH/SM/PH/SYP/RE), Dupont, MolexTE, KF2510 Terminals

I love playing with microcontrollers and small circuits. For the past few years I've been using a crimping tool designed for Dupont connectors to make crimps on smaller JST-style pins. As can be imagined, it didn't work well and I often had to rework the connector several times to get it to properly crimp and fit into the plug. This tool changed all of that. It has a variety of different size pins and connectors that it can crimp, so it has plenty of versatility. I've become addicted to the ratcheting style crimper - this one is comfortable to use and works great. I couldn't be happier!

Had to repair a motorized recliner control box wiring.It was easy to use to replace the broken ends.Also has a nice variety of connector shells.The included crimp tool works well.

Glad I bought it. High quality. It took a couple of test crimps to learn how to use (my first tiem) but now I can make and fix cables for my ender 3 pro.I will be buying 2.0 to complete the other size used on ender 3

Send to be some QC issues with the connector and pin counts. The included instructions are clear and useful. The overall quality of the crimp tool is excellent.

Overall this is a great set. The crimper feels solid, and the big assortment of connectors is just what I needed. That said, making these adapters is trickier than expected! The included instructions are good, but be prepared to waste several pieces before you get it right (if you're an absolute noob like me).Look closely at the metal part for the little "tooth" that latches into the plastic part. It's easy to crush that in while crimping such that it won't secure to the connector. My workaround was to make sure that the latch/tooth was hanging about 1mm out of the "back" of the crimper before pressing down; when I aligned the metal pieces flush with the front, I kept mashing it.It's a bit arts-and-craftsy, but you can definitely get a hang of it with some practice. The crimper works great, it's me that could you some improvement!

The hardest thing is trying to figure out the specifications for the different types of connectors as a hobbyist. I had ordered a kit of JST connectors from china because the seemed like the most common type. After reading a bunch, I was able to determine what I needed was the JST XH type but I did not have a crimper. My 3D printer was getting a height sensor and of course the 'high qwality' chinese kit did not have the proper connectors for my Ender 3 V2 motherboard. I decided that since this kit said the jaws were EDM cut, it might have some accuracy. I work in aircraft and the tools are VERY expensive, so when I found these, I thought I would take a chance.Came in a nice retail box, the actual kit box is SUPER nice with a removeable tray to store a complete variety of the connectors, and at that securely so they don't migrate into other compartments. The crimpers are better than average with the jaws being very accurate. I was able to clip the 5-wire harness flat across, install 5 new female ends and snap them directly into the connector for a exceptionally professional result. It also does SM types too, but I would just purchase a separate pack for cheap. Great for drones, electronic projects and upgrades. The main reason I got this specific set is that they said 'High-precision jaws' and I can attest that they are. I crimped some 22ga Tefzel aircraft wire and the crimps all came out perfect, with the crimps secure and the strain reliefs not damaging the wire insulation, like in the ad photo. I HIGHLY recommend this kit.

A very well put together kit, with excellent instructions written not in Chinglish, but by someone with fluency and technical competence in both English and the construction of wiring harnesses . I strongly recommend this kit.

I'm always impressed by the number of things we can get within a few days from Amazon. This connector and crimper set make me wonder how I would have gotten something like this 15 years ago. I have only crimped a few connectors and the crimper took worked great, the crimps look well made and snap tight into the housing. I would definitely buy again, but I assume I won't need to. The took seems well made.I have a crimper for standard .093 and .062 but it is too wide and smashes the small pins. This crimper allows the pin to it firmly in place while you push the wire in.
