Review on Orion Motor Tech AC Gauges: Complete 3-Way Automotive AC Manifold Gauge Set with Hoses, Couplers & Adapter for R134a R12 R22 R502 - Freon Recharge Kit for HVAC by Alec Winsor

I bought this primarily to fix an air conditioning problem on one of my cars that I'm still working on. In the meantime I'm just using it to make sure everything looks good on my other two cars. So I plugged and unplugged the quick disconnects maybe 4 times in total. The blue (low) side of the quick disconnect has already failed. I've replaced the small plastic grommet on the end of the blue hose that connects to the blue quick connector to no avail. I also replaced the yellow hose with a blue one just to make sure it was a connector and not a hose. It's a shame that I've only had this thing for a few days and it broke even after very little use.
