Qibaok Crimping Tool Kit Ratcheting Crimper with 1550PCS 2.54mm Dupont Connectors and 760pcs 2.54mm JST-XH Connectors for AWG 26-20(0.1-0.5mm²)

This crimp has been a life saver. I got it just for a small project, but it worked out so great, I am starting to use it for all sorts of electrical projects. While there are probably much better crimping tools out there, the prices are outrageous! This is a solid crimp with a full set of supplies for 1/2 to 1/10 of the price of some of the others I have seen.HIGHLY RECOMMEND!

I bought this to switch out some connectors on some Stepper Motor cables, and to use for making the JST connectors for my Radio Controlled aircraft and cars. This works well and allows me to control the cable lengths and replace damaged connectors. There is a variety of connectors (some I will never use) but for the $$ spent I'm very satisfied. I strongly suggest you follow the instructions and you will find this tool and the connectors get the job done.

My only major dislike at this point was that the package was already open for the crimp tool. So clearly it had been returned by another purchaser most likely. However, it does work just fine, so maybe the previous user wasn't sure how to best use this crimp tool. That being said, I have used more friendly crimp tools, but once I got used to how this one works, I was able to build the harnesses with pretty good success.One other complaint would be that the black connector package has no connectors for the male pins. This isn't a major issue since I bought the kit for the female pins and holding connectors, but it makes me wonder why they included these pins.I really do like the white connectors that are board mountable with the mating harness connectors. These lock in quite well.

The Crimp Tool: I've used OEM crimp tools for many years (decades actually). I didn't know what to expect from a generic tool. Much to my surprise, this really works well with one slight issue. I found this works excellent on the DuPont crimps and on Molex 08-50-0114 crimp terminals. For the PST style, it works but takes more practice on figuring out where to align the pin for best crimping, since the head is a bit too wide for this terminal (as is almost every crimp tool I have seen). It might take a little adjusting of the tool setting to get it right but now I hit very close to 100% perfect crimps each time. The handles are very comfortable, and the operation is smooth. It is a robust and well-made tool.As for the Dupont and JST headers, they all worked great with no issues. Both may be generic rather than OEM (I honestly don't know) but they still work fine. I've used hundreds of them so far. The assortments provided were an excellent starting point until you see which sizes you need most. And it is nice to have an assortment for prototypes and the occasional repair.

Crimps hold very well - just takes a little practice. For the price this is a great product!

I do a lot of prototyping with STM32, AVR and others. I have tried two other "multi-connector" crimpers that do a good job on heavier connectors, but when it comes to the DuPont style neither has worked. Because the jaws are too thick, they distort or crush the connectors. And I've had a LOT of practice trying.This one does not crush or distort anything -- because the jaws are much thinner than my other ones. It simply worked on the first try. Now to be fair, beginners who have not crushed and destroyed as many connectors as I have might need a little practice. For me, from the first crimp everything worked perfectly.If you do arduino/raspberry/etc and use DuPont-style connections, this is the one to get. But note that it only fits two sizes, unlike one of my other kits which destroys DuPonts but does a ton of other crimps.Thanks to the great success I've had with this tool in the last day, I'm considering milling down the replaceable jaws on one of my other tools to see if I can make that one functional.

Crimper is too sharp and squeezes too tightly, breaking the wires every time
