I am so happy with the crimper making my job easier when crimping different wire connection. It's all in one tool, easy changing dies for my crimping needs. Recommend the 11 pcs kit and add a variety of connector kits. Nice rugged box to keep all together in one place and has compartment to add to the collection of dies. if you have questions, they get back promptly. Very happy with the purchase.

I was very impressed with the technical support I got on what die to use for certain application. Also I have been impressed with the tool itself.

Idea is good but implementation is poor. First ring terminal crimp and it jammed, die is not the correct size. Swapped to my dedicated crimper and completed the job. I would spend my money elsewhere.

I have wasted 6 MC4 ferrules trying to connect them to 14AWG wire using the I2 dies. They always end up mashed and deformed. I finally succeeded using the middle opening (labeled 12AWG). That seems to form the proper crimp that looks as expected and seems to hold firm. Am I doing something wrong? Has anyone else experienced this? It is almost as though the die is not sized properly for 14AWG. I was using MC4 connectors from 2 different manufacturers, each sold as being suitable for 14AWG-10AWG.

I just bought this tool with 5 dies that match most of my needs and it works great. The tool itself is sturdy, nice to grip (for my hand size) and easy to release (all things I have had issues with with similar crimp tools), the dies I have used (A3, C, D) have been pretty much flawless (a little paint that wasn't centered for the A3 one - who cares).
However, I would really _love_ to see a "C1"-die for smaller dimensioned open barrel terminals, such as for dupont and JST-PH. I am sorely missing those dies before I can get rid of my old crimp tools.
