I had also bought one of the cheap vice-held sets that wasn't fit for purpose. This, however, is a good quality item that produces perfect double flares every time. The grip holds the pipe firmly without damage and without needing to overtighten the nuts. The best thing is that all the critical settings, e.g. how far the pipe protrudes, how much the formers should be tightened down, are all controlled so no guesswork is required. Also, the formers are kept square to the pipe producing nice symmetrical flares - this is the big weakness with the cheap sets. Great tool and well worth the money.

Better than other pipe flange we have a lot easer to use

This is an excellent tool. Nearly fool proof, just don't forget the tube nut, don't forget to grease the die, and work it back and forth as you run the die in. I like to go 1/3 forward, 1/6 turn back as I run the die in. I am using 4lifetimes stainless tubing, it is fairly malleable and I haven't had a flare split on me yet! Can't speak for other cheap tubing though. This is a tool that will last a lifetime and worth every penny!!
