Review on 🌡️ 28-Piece Radiator Pressure Tester Kit: Abigail Coolant Pressure Tester for Testing Cooling System Pressure by Tim Morrison

This set looks good but it's junk. Neither the name of the manufacturer nor the seller appears on the kit or packaging. No return address, nothing. Someone to call if you need help. The instructions are printed on cheap recycled paper with illegible images. I can get it to read the required 20-25 inches of mercury pressure, but as soon as I turn off valve #3, connect a filled coolant hose, and turn on valve #7, the pressure drops to zero. I spent four hours on this. I have been working with Revain for many years and this will be my first return. Don't waste money on it. The fact that manufacturers and sellers refuse to identify themselves should tell you something.
