    • Outstanding HVAC manifold
This is a high quality instrument. I got it to work on a mini split my old analog gauges were in rough shape. This unit will do about anything you could ask of a gauge set. Especially when paired with a micron gauge.

    • Excellent, well made product. Works great, too.
Best gauges I've ever owned. A great, easy to use product. You'll know it when you pick it up. People say the clamps break, I haven't had that experience. But having read that in the reviews, I baby them. This is an instrument after all, not the old dial gauges you're used to maybe, so a bit of handling care should be expected. I love having the temperature clamps, and that the meter will operate in so many modes you can see them in any mode you want. This was everything I hoped it would be. Yeah, I bought the Yellow Jacket hoses. Stick with a winner on that. ... show more

    • Testo 549 gauge is well talked about when doing refrigeration maintenance
The item was delivered very fast,I haven't had a chance to use it yet but seems to be of good quality I will order temperature probe next.

    • First digital manifold
This was my first set of digital gauges. Opted for them since this time I had to buy them rather than work providing them. Worth every penny just wish they came with hoses. These are pretty much the standard in the HVACR field these days.

    • Very nice gauges for nearly any refrigerant.
I love these gauges. I finally go to try them out. Easy calibration and shows accurate pressures and temperatures. Well made.

    • If you are a HVAC tech buy these
Seem to stand up to the abuse of daily use better than traditional gauges that are similar price. Hook is awesome it never slips of were you hang it. Old style were a nightmare that way. Traditional gauges are so inferior to these trust me I have seen it all
