Very nice invention.
If any of you want the easiest method I've found to be foolproof, here it is. A simple 20oz clean Gatorade bottle half filled with fluid, a clear hose about 2-3' long that fits SNUG over the bleeder, a bleeder wrench and some brake fluid. You merely crack the bleeder open and slowly push the pedal down and pull it up. Keep the reservoir full and keep doing it till all the bubbles are gone out the top of the fluid in the bottle. The hose must stay in the fluid. Once the bubbles are gone, tighten the bleeder. I have not "pumped brakes up" in at least 20 years and I always get all the bubbles out and end up with a firm pedal..........
