  • Great crimper set
Style: Crimping Tool Set - 11 PCS
I was skeptical, even with the good reviews, but if you're looking for a sturdy, easy-to-use crimper set, this is a good choice. I wasn't sure about the magnetic system for holding the crimp dies, as I'm used to using ones that have screws to hold them, but these work well. You open the jaws, pop one set out, and pop another set in. It's that simple. I've used this set a few times now, and the dies stay put. It's nice not having to have a #1 or #0 Phillips screwdriver on hand or worrying about the inevitable search for a dropped screw. The kit covers every termination I'll ever need and then some. Out of the box, the crimps are secure and not over-crimped so the insulation is still intact, but it still allows you the ability to adjust the crimp pressure if needed. The included insert that shows what dies to use for which terminals is a nice addition and very helpful as all of the dies are marked ie "A1" A2" etc. and the pictures show the dies by that number. This makes finding and using the appropriate die a snap. So far, I'm very happy that I made the purchase. ... show more

  • Could be better
Style: Crimping Tool Set - 8 PCS
This has generally been a good tool, but the die for heat shrink connectors twists to the side due to its offset instead of staying straight. It still makes a usable crimp, but I'd really rather it didn't twist. I've had this for 4 years and don't need it often. It's not worn out. It just doesn't hold the die as well as it should. I really don't understand the reason for the offset in the heat-shrink die. It would work much better if the die was centered. I'm hesitant to buy another brand, because most others look identical to this one. There are a few ratcheting crimpers made specifically for heat-shrink connectors, and at least one has a centered die. Since that's what I use most often, I'll probably buy it. ... show more

  • Efficient and Reliable Crimping Tool
Style: For Heat Shrink Connectors
This crimping tool has quickly become a staple in my DIY toolkit. This ratcheting wire crimper is incredibly efficient, providing a secure and reliable crimp every time. The ratcheting mechanism ensures consistent pressure, making it easy to achieve professional-quality crimps without much effort. One of the standout features is the ergonomic design. The handles are comfortable and reduce hand fatigue, even during extended use. The tool is well-constructed and feels durable, which gives me confidence that it will last through many projects. The adjustable crimping pressure is also a great feature, allowing for precise adjustments based on the connector size and type. The only minor downside is that it takes a bit of practice to get the hang of the ratcheting mechanism, but once you do, it makes the crimping process much more efficient and consistent. I think this crimping tool is an excellent investment for any DIY enthusiast. Its reliability, ease of use, and high-quality results make it a must-have tool for anyone working with electrical connectors. Highly recommended for its performance and durability. ... show more

  • This one is the best ever
Style: For Insulated Nylon Connectors
Working is easier. You can put the colored connector in the jaws and close, it will hold the connector in place then you have both hands free to hold the wire and crimp one side. Next insert the other wire and crimp the other side. I often put the handle down on the bench top and lean into the top handle. It does take strength to close the crimp. It stays locked until it is closed entirely then it opens easily. It does not open until it closes fully so get it right the first time. ... show more

  • Great company, great support!
Style: For Insulated Nylon Connectors
I had a small issue with the crimpers I purchased on Amazon, and Wirefly's email support was extremely responsive and immediately issued a refund! You can't get any better than that! That said, the crimpers are fantastic -- I don't see how they could be any better.
