Can't beat this for the cost. I have this exact tester and love it. Care needs to be used when pressurizing the cooling systems. These wont vent to the air or the recovery tank so pressure continues to build. You can blow out the seams on the radiater if pressure goes too high. We run from 6 lbs to 13 lbs on out cooling systems. I feel 16 is just too high for the size of the radiaters. Even better idea is running Evans Waterless Coolant. No water... No pressure. Everything lives longer. Just need to make the radiater cap push fluid into the recovery tank with no pressure. Just fluid expansion from heating it up. then it naturally flows back.
