Quality seems good so far with a few uses.
Works great so far, no issues. It's not a tool I use everyday but occasionally, completed several ferrule crimps and I'm pleased with the results.

It's a tool that does what it does!
Great ferrule crimping tool... I feel weird for just now ordering one at the age of 51, but better late than never!

Works well, good value
Works well. I like turning up the pressure for a tighter crimp than the factory setting.

If it's Klein, it's mine! Excellent tool super dependable, well made, perfect crimps.
Excellent crimpers for ferrules. Much better than the lower quality imports which tend to crush and deform the ferrules. This Klein product has proven to be dependable and wonderfully durable. The product looks well made with precision fabricated parts and close tolerance jaws. I've seen ferrule crimpers as twice the price not work as well as these Kleins.

Solid tool, good deal
Good value for the money, does not crimp as square as pricier options which would be nice for smaller square terminals that I deal with often. For 130+ less than the knipex and only 15 or so more than the no name Chinese brands this is a no brainer.

Very easy to use
Completes secure crimps with minimal force needed. I was pleasantly surprised to find that it was able to crimp 6awg as well as 2x10awg. The 2x10awg ferrule I used just barely fit in the tool’s die. This exceeds the 10-22awg the tool states it can crimp. This is not the cheapest crimper out there but the quality is worth the investment.

Perfect crimps every time
Perfect crimps every time with no effort. If you close these up as if you were crimping a connector but don't go quite all the way, they stay locked in that position and will take up less space in your toolbox.
