Do any of you guys use a Superheat/Subcooling Gauge made by Robinair or J/B. It looks very cool and Ez or are they waste of money?

I use the JB SH-10N it's a great meter and have checked it against the Fluke temperature clamp very accurate and it does the math for you. http://www.jbind.com

I use the J/B SH-31N. Wouldn't leave home without it! I actually have it strapped to my center manifold gauge hose. Works beautifully. This is my second year using the gauge without any problems. Constantly displays superheat or subcooling depending on how you have it connected. Let me know if you get one. I'll try to take a pic of mine and post it. I use it on every job that my gauges get connected to. An investment you won't regret.
