I think you can just lump them in with all the other Chinese stainless brake lines. These were the first low cost China brake lines I discovered, and I bought a few. Then I found them for even a few dollars cheaper on eBay so have been getting them there now. So far, all have held up fine. The only "gotcha" with the eBay lines is most all seem to have the end fittings mounted in the same plane, parallel to one another. This works great if your MC has a front mounted line, not so good if the line mounts at the end like the stock MC. Banggood used to sell some lines that had the end fittings at about 90° to one another. They worked well on the stock MC.
