Review: Huge upgrade to chinesium crimpers - Compared to my no name aliexpress crimping tool, these make a more secure crimp, and they work better with smaller wires
Review: Kinda luxurious! - This is a really quality crimp tool, comfortable, solid and well balanced. It's kinda luxurious TBH. It wont do all the work for you and it takes some practice and can be a bit fiddly at times to get the doohicky positioned in the right slot (story of my life) but then you squeeze and its perfectly crimped. As far as these things go it's top notch. This is one you can put in your will even if your only intent is to mess with your kids.

### ⭐⭐⭐⭐⭐ Huge upgrade to chinesium crimpers

### ⭐⭐⭐⭐⭐ Kinda luxurious!
*by J***R on October 30, 2025*

This is a really quality crimp tool, comfortable, solid and well balanced. It's kinda luxurious TBH. It wont do all the work for you and it takes some practice and can be a bit fiddly at times to get the doohicky positioned in the right slot (story of my life) but then you squeeze and its perfectly crimped. As far as these things go it's top notch. This is one you can put in your will even if your only intent is to mess with your kids.

### ⭐⭐⭐⭐⭐ definitely worth the price
*by L***. on July 25, 2024*

These crimpers work real well and have enough different sized dies to accommodate many size wires/pins. You have to use your own judgement on which size die to use, and not 100% follow the size chart that comes with it. So far I've used the crimpers for just the tiny JST XH 2.54mm series pins, and the smallest die was appropriate because it's narrow and matches the pin size. In the first picture you can see each of the 4 dies has a small side, and a larger side. The "dividing line" between the two die halves has to align with the white line in the second picture to properly crimp the wire and insulation in the pin. The insulation is crimped by the larger side of the die. The third picture shows how the pin is placed in the die. If you look closely, you can see the tabs that grip the insulation are seated in the larger side of the die.
