I do HVAC for a living. I have used Yellow Jacket and Hilmore gauges with great success. They seem good, I hooked them up to my personal unit to make sure the ball valve hoses and also the manifold valves didn't blow out. They worked as they should. The point where the hoses attach to the manifold seems rough due to the chrome finish, I'm used to smoothing brass fittings. What I dislike the most are the black 3-1/8 Spider treads, they don't fit well and feel cheap. They look better than the Yellow Jacket in my opinion, but in performance they will compare more.
