A little disappointed with this tool. Doesn't work as well as expected. Brake line slips in the clamping area. Does not hold the brake line completely straight if there is a slight curvature in the line. Does not always press the pin straight into the line. Under strictly ideal conditions it does work. Otherwise it can be difficult to get it to work correctly. If you have spare olives and pins and your brake line has some spare length it's not such a big deal. I just don't want to waste those parts because they aren't re-usable after you try them once.
Used for hundreds of builds and repairs. Adjustable clamp compression, allowing for careful barb insertion. Pro tip: Poke your clean cut hose with a straight pick. This will ease the barb in straight. 10 out of 10 for this or the "SRAM" branded version.
