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 Brett Jarvis

For the price, you can't beat Guage. No, it's not Snap-on, nor is it hundreds of dollars at stake. The Dual is easy to set up, I just wish I could calibrate the device more accurately. A better guide would help and make it easier not to make silly mistakes when ordering for the first time. Remember that the laws have changed, you need an adapter for new refrigerant cylinders. But it's also great because if you keep the old one, you can now restore it and save it, or reuse it or dispose of it properly. Would definitely buy the same again, just really wish the r134a socket adapter was part of the original kit.
