IWISSXH2.54/3.96,PH2.0,PX,JST,Molex,Dupont Terminal Crimping Tool SN-01BM Rachet Crimper AWG28-20 (0.08-0.5mm ²)

These are very high quality and work great! I had to crimp many connectors for my 3d printer and they all turned out perfect!

I use the Iwiss crimper tool with the SN-01BM die to crimp the pins for JST XH 2.54mm connectors, using 22 AWG stranded wire. It works extremely well. The fact that it crimps in both places (the wire insulation and the wire, which are different sizes) simultaneously, which means you don't have to crimp twice, is very convenient. The ratchet feature is also very convenient. The tool also releases automatically as soon as it's delivered the precise amount of crimping force so you don't have to think about that.Specialized crimping tools used by professionals cost hundreds of dollars (some even more!). This tool is under $25 and it works perfectly.There are so many types and sizes of connectors and tools that you have to select the right tool for your connector. Assuming you've done that, you need to learn the right way to use it, e.g. which way the pin goes in the crimper, where to place it, how much insulation to strip off, proper wire gauge, etc. For those folks who say they haven't had a good outcome with this tool I can only imagine that there is some detail like the above that they haven't attended to.

Works well jaw is tight so u can trust it But cost is too high
