I have this tool and use it extensively. It works like magic. Makes using the cheap harbor freight/Princess Auto POS feel like a toy.

 

The one time I had to use it on a car to repair a broken brake line was a pain, as it relys on being clamped in a vise.

 

The copper/nickel alloy brake line is magical as well. The stuff that Fedhill sells is priced really well, and it was all I used until one day I ran out in the middle of a job. Called around and found an outfit in town (Greggs Distributing) that stocks some of the BrakeQuip tools and lines (they also make SS braided and standard brake lines to order), including their version of the Cunifer soft line. It was even softer and easier to work with than the FedHill stuff. It was more expensive, like x2....

I really like the Fedhill products. I have never used their flair tool but it looks like the right tool for the job.
