Good line, use good tools
Stainless, so use a good flaring tool- I have access to an Earl's Plumbing Tool, so no problem. This have to be "Dead nuts" on or they will not seal like mild steel

Good Quality
I used this to make brake lines for a boat trailer. It is able to bent by hand and did make fairly tight radius turns without kinking. I also double flared it with no cracking or issues. I did purchase the Titan double flaring tool and it worked perfectly with this tubing. I did make some plugs to close off a fitting on the brake calipers and the tubing was able to be crushed on one end, then folded over without cracking, like most stainless does.

Tough Stuff
This line is harder to bend and flare than plain steel line but not too difficult if you have the right tool. You only do it once with stainless steel so its worth the extra effort...it should outlast the vehicle. I would not recommend trying to flare stainless steel line with the typical cheap flaring tool. I had one of those once and it broke the flaring disc on soft steel line so it probably wouldn't handle stainless steel well. I use an Eastwood tubing flare tool that clamps in a bench vice and has a long handle that provides the leverage you need. I see Amazon has that tool and a less expensive version by TGR. Excellent tool that makes both 45 degree and bubble flares.

Excellent product to work with, form easily , flares come out nice (all types)
Good product to duplicate factory brake lines. I used this line along with a new Capri brake flare tool and all four lines came out awesome! I went with stainless so I never have to worry about lines giving out again! Do it once, do it right, make it last. Price difference between Stainless and reg steel is negligible so no point cheapening out for $8-15. In the Spring I’m going to redo the lines on my classic cars. I already bought 5 more rolls !

Good tubing.
Made all new brake lines for my restomod C10 build using this line. Chose to do single flare with appropriate fittings, have had no leaks over 2 years. Using a bender this line bends very well, can also be bent by hand if you know what you’re doing.
