solid tool
solid tool. Yes it’s heavier than the cheap ones but very solidly built and does a great job crimping. FYI, some people don’t like the grip required to release the ratchet mechanism. Look closely at the photo. It has a release lever and it is adjustable so you can set to where you want it or just flip the lever.

Solid functionality
Fantastic crimp, every time. Large handles help you get leverage for easy crimps. May be more difficult for small hands.

Pays to get quality
It works extremely well with secure, tight crimps and it can be easily be adjusted to a persons grip strength. Quality tool and good value for the price. I like that it double crimps and is easy to align the joint. Solid tool

Massive and heavy
Clearly well made – not in the USA – seems Klein Tools joined the many manufacturers going east. The crimper is heavy and a bit awkward to use. Requires very strong and preferably big hands. I don’t have big hands but managed ok for the few crimps I needed done. It does have a “switch” that gets released and ready for the next crimp only when the handles were pressed really hard to finish the crimp. Had I needed to use it all day long or for prolonged periods – it would not have been my choice tool but for occasional usage for someone who appreciates well made tools – i will keep it. I purchased another brand for almost half the cost of this one and it is lighter. It worked fine too – i am keeping both (2 different places).

Great tool for cheap
Great tool and it crimp on both sides so it doesn’t matter which way you load the ring terminal

Chose this tool based on other recommendations on the internet. Wow! Crimps very well, both the wire and its insulation. Crimps tight but still without destroying anything. No comparison with manual crimping by hand, the difference is night and day, and all this for an affordable price for such a good tool.
