A little pricey for the DIY'er but works great. I've never been disappointed in any Mophorn tool that I have purchased. The crimper is easy to use and the finished crimp looks factory. I would recommend this tool to anybody looking for a crimper.
I got this for my sons shop after his expensive name brand one broke the first time he used it and they wouldn’t warranty replace it. You could tell from the break it was the bad metal. This one has been used numerous times and has been perfect every time.
Quality product. Takes some arm strength to clamp these down. Work for an old man, easier for a young one. Local AC shops wanted $20 per crimp. I had 12 with 3 sizes. Saved me a bundle. Used these on a Vintage Air hot rod system.
