Review on Enhance Automotive Performance with 8MILELAKE 21pcs Handheld Vacuum Pump Set Tester and Brake Bleeder Test Kit by Prem Robinson

overall not bad not as good as I would like. I can pull -20 cm of pressure when I'm working on it. The tips didn't help. The hose becomes cloudy after being used to bleed brake fluid. It works, but I had to buy my own cell phone. A tip for suction bleeders who have always resorted to the pump method: Almost all brake bleeders bleed around the threads. Take them off and cover them with silicone or teflon tape before attempting to vacuum them out. Losing a small amount of fluid in this case is much less of a headache than sucking in air for an hour wondering what's going on. Just my experience.
