Query: not worth it

I'm usually pretty good at making lemonade out of lemons. But there is nothing here that is any good. Make your own, PLEASE. Don't waste your money. I made one out of clear vinyl tubing from Ace hardware (about 3ftlong). Make sure it will fit your bleeder screw thingy. A empty pickle jar with a lid, poke a hole in the lid with a screw driver, run the tube down to the bottom and punch an air hole in the lid also. Connect the tube to the bleeder screw and for me what worked well was to set the jar up on two milk crates so when you pump the brakes the fluid has to work its way up the tube this way there is always fluid near the bleeder screw. I saw so many tiny air bubbles come out of my system.I love the way my brakes feel now. Fresh fluid and no air in the system. Nice and tight not spongy. Always keep your reservoir full.
