As a retired aircraft electrician I am more than familiar with hand held crimping devices. This crimper has a smooth and efficient ratcheting mechanism and provides a uniformly even crimp area to the splices I have used it on. The handle is quite comfortable and the leverage is quite adequate to properly crimp AWG 10 splices. Overall I am very pleased with the initial quality of this tool. It appears to be a well built device with the only question being longevity. If this crimper prooves to provide years of service I would have no problems awarding the entire five star rating.

THIS THING IS AMAZING. I cannot believe I never thought to look for one of these. I have been suffering for years using the 2-in-1 strippers and crimpers. Those things are crap. Awkward to use (hafta feed the crimps through the back half of the handle) and unreliable crimping. This machine can crimp anything quickly and STRONG. You can sit there and tug on the connections all day. More likely to break the wire elsewhere than the crimp. It's hard to get excited about crimping but I sure am now! Buying another one tonight!

I havent used these much yet, I bought them for a upcoming wiring project on my race car but so far Im loving them! I bought some shrink tube crimp connectors and had good luck testing these out with everything from 10-22 gauge wiring.

Of comparable crimpers found online for sale, these are the best bang for your buck! Spend a couple of extra dollars and avoid the hassle of working with cheap, unreliable, poorly performing offbeat or generic brands. You will be please to find the outstanding quality and performance from these crimpers. They operated properly the first time every time, making rock solid reliable crimps every time. The heat shrink style connectors are not damaged by these pliers. There is an adjustment (which compensates for over or undersized connectors and different insulation / heat shrink thicknesses). The adjustment requires the removal of a screw and is very stiff to change. That aside I would rather a stiff adjustment vs something that falls apart. These are a must if you work with heat shrink connectors. Though somewhat bulky for tight areas, they work great. The ratcheting design ensures the same crimp every time! Even if they may cost a dollar or two more, you, your coworkers, and customers will gain from these time saving pliers.

I bought these crimpers on November 24th, 2016 and received them on November 26th. They came in a blister pack and placed in a small box wihtout packing material, none was needed, it's a tool. I have used it for crimping insulated electrical blade connectors and the barrel connectors from the small reds to the big yellows and they have made a solid crimp each and every time. It makes a double type of crimp that is much more solid than the single crimp from the scissor type crimpers. I have used them in automotive wiring and in household electrical wiring projects and love the one handed operation and the solid feel of the resulting connection.

The price was reasonable compared to other crimpers and the feel of the tool is solid making me believe it will last for years. These is no play in the working of the mechanism and it seems to have a high build quality. I am considering another purchase of this tool for my shop because I have to go to the work van to retrieve this one every time I need it at home.

I am happy with this tool and will not go back to the old way of crimping with a cheap single crimp scissor type crimper.

Pros:
Solidly constructed
A comfortable grip
Solid crimps
Reasonable price point

Cons:
None

***UPDATE***
I purchased a second pair of this tool for use at home in my shop and it works just as well as the first pair. Will never again try crimping wire connectors without them.
