I have had this tool for 1.5 yrs. Really good quality. Great to have the correct crimp jaws for the appropriate connecter. I love the crimps because they are clean and secure. However, every time I make a crimp, the tool does not release like it should so I sent a query to customer service and was instructed by Wirefy to use a screwdriver to release the handles. PIA, there must be an adjustment or is this a faulty tool?

I bought wirefy heat shrink butt splices and misc other connectors for compatibility. Connected several 16 gauge wires. Used the 16-21 gauge butt splices and the jaws for heat shrink butt splices. 30% of them failed and had to redone. Had to crimp each connection twice (double the length of the crimp). Have a low cost wire stripper that can crimp the basic 3 sizes and rarely has a pull out failure. Wanted a tool designed specifically for heat shrink, insulated connectors... to insure no tears in the coating. Hopefully the performance will improve. Could’ve bought a lot of heat shrink tubing and none insulated connectors and stayed with my old crimper otherwise.

The Wirefy Crimping Tool Set is the perfect crimping tool. I have a drawer full of cheaper and lesser crimping tools and there is no comparison. The Wirefy crimper is effortless and with the interchangeable Dies you can crimp every conceivable type of connector. I am replacing all; my other crimpers with this one tool that is so well made it can last a lifetime. Buy It! You won't be sorry.

Nice to upgrade my crumpets with a full set that is easily upgraded by adding individual dies later on.

Simply nice to have what I need. When I need it.
