Review on AURELIO TECH Manifold Refrigerants Adjustable by Vic Alexander

I was hoping this would work as well as the standard Yellow Jacket brand that HVAC folks use. I'm a homeowner, not an HVAC specialist, and have to charge the central air conditioning myself due to the lack of HVAC specialists these days, long maintenance times and high prices. I was not disappointed with this gauge set. In fact, I put it away for a few days with liquid refrigerant trapped in it, which I only noticed by the little sight glass after I pulled the gauge back out. I noticed that no coolant had escaped in the whole time. I think this kit is missing a set of built in ball valves or knurled pressure valves. Without them, you'll lose all of the refrigerant in the hoses when you disconnect, and the liquid line disconnect will be messier. The kit isn't advertised with it, but I'm just pointing it out.
