Well made, works well
Well made and works flawlessly. A previous model I had purchased would always lock the finished crimp into the jaws and couldn't be removed without destroying the terminal. This model does a perfect job everytime.

It’s easy to use, even for beginners
This Crimping Tool is an excellent tool for precise and consistent crimps. It’s easy to use, even for beginners, and produces clean, professional-quality connections every time. The ratcheting mechanism works smoothly, and the jaws are well-aligned for Dupont-style terminals. It feels solid and comfortable in hand, making longer projects much easier. Fantastic value for the quality
