Review on B4B BANG 4 BUCK AC Diagnostic Manifold Gauge Kit: Ultimate Air Conditioning Charging and Vacuum Pump Evacuation for R134A, R404A, R410A, R22 Refrigerants by Jason Flippen

Haven't had them for a long time but I can say the quality is good, not branded but they cost less than $100 so a good deal. My only advice would be to replace the cheap white hard plastic gaskets in the hoses with a Robinair brand 1/4" gasket kit, set of 6. The Robinair gaskets fit very well and require some work, but are 100% better than the original seals!
