Review on Efficient Brake System Maintenance: Introducing the Cardone 10-5000MCB Brake Master Cylinder Bleeder Tool by Robert Worlds

Helps with bleeding, but nozzle doesn't always seal tight when brake fluid is forced into ports. Sometimes air got into the rubber nozzle, causing the brake fluid to shake and bubble. I had to put a lot of force into the syringe to prevent that. Venting the syringe can also be extremely messy as the syringe handle is very sensitive to force, so be careful where you point the syringe. In general, this removes air faster and requires less physical labor than the traditional method of bleeding the MS, but whether you can fit the black cap into the ports/inlets depends on your MS design. I've used this and the traditional method (using clear tubing) and got the job done faster.
