Yangoutool Micro Molex Crimper: 32-20AWG (0.03-0.52mm²), Compatible with Molex, JST, JAE, D-Sub, Precision JST Crimping Tool

does the trick cheaply. The real molex crimpers were 4-5 times the price and for light use these do a great job and beats the hell out of a needle nose.

I needed to crimp Dupont jst and molex connectors and originally bought https://www.amazon.com/dp/B016B39EPQ/ref=cm_sw_r_cp_apa_fabc_HSJ44V8HDR1QYSEDH7S9?_encoding=UTF8&psc=1 which has jaws that meet at an angle and is a bit thicker and didn't work well for me because the edge of the connector sat approximately 2mm inside the clamp making it darn near impossible to tell how far you had inserted the stripped wire. These crimper truly are for the tiny connectors, making it easy to get great crimps on them. They are thinner making it easy to see how far to insert the wire and the parallel jaw closure means that the crimps are even and straight. I followed a YouTube video link to find these and am glad I did. I made four perfect crimps straight out of the package in less than 6 minutes (most of that time was spent lining up the connectors and stripping wires), with the first tool I struggled for 90 minutes with 6 rejects...

Works perfect for crimping open ended terminals. Great value for these style of crimpers. Only thing would be if they ratcheted but these get the job done.

I used this product for some AMP 040 terminals on my motorcycle. I had not done anything other that regular crimp terminals but was able to do 5 terminals with no errors. There was not much in the way of instructions but my experience plus a few videos were adequate to pick it right up. This will greatly expand the types of terminals I can crimp.

Work great

I used this tool to crimp mini terminals when installing a car stereo. It is easy to use, but sometimes it gets stuck when crimping.

It makes clean crimps on pins the cable holder legs at end however have to be closed manually which kinda sucks but overall no issues

I bought this for one big job and future small jobs, so I did not want to spend a lot of money on one. I did not buy it for daily wiring, and having said that it is well made for the price, I believe I will get many years of use out of it.

Works just fine, I suggest doing a few practice crimps. I initially I was going a little too hard/tight and the connector was warping a bit which seems ok until you try to insert it into the plug and then it doesn't want to properly stay in. You want it snug but not so tight that the whole thing bends. This is also the benefit of this one over a wratcheting version, you have the option to vary the crimping pressure.

I have a few molex crimpers that I paid a couple hundred dollars for, I didn't feel like buying another pair for this job. These ones actually work just as well as the molex ones, I don't know about longevity but so far they've been okay.

I recently purchased to crimp on some uninsulated connectors while building a guitar. It worked, but still required some fiddling to partially pre-bend the tabs prior. But in the end it worked OK. Just a heads up, it is not perfect.

Works great. Very happy with this crimper. Easy to uses and worked every time.

For the odd time we need it, it works as it should! Durable so far, grip is comfortable.
