HVAC Gauges 93 Refrigerant Detection Digital Manifold Gauge Set HVAC Pressure&Temp Test HVAC Manifold Upgraded Ball Valve Digital Refrigerant Gauges with 3.5" LCD Display, Refrigerant Hoses,Temp Clips

This is actually a DUOYI model Y522A unit. Not sure why they blurred the labeling out in their pictures, but whatever. The main point is this is a very affordable digital gauge unit with a lot of features for the Do-It-Yourself guy who wants to work on his own home A/C. Like most of the other reviewers, I agree the hose set that comes with the kit is cheap leaky junk, but you can probably fix the leakage with some good quality seals for the ends. However, I didn't want to take the chance so I bought a really nice Uniweld EZ3HS 36 inch low-loss hose set and it worked beautifully. The only quirk I've found was that every once in a while, the gauge set would zero out the pressure readings all by itself. It was annoying, but all I did was turn the unit off and back on and the absolute pressure gauges usually showed close to what it's supposed to be. Luckily for me, I have mini-splits with electronic valves so I just charged my systems with amount listed on the labels and don't really have to use the pressures like with fixed orifice or TXV systems. The ball shutoff valves are an improvement from their previous style valves and the sight glass is also very useful so that you can see the liquid and know when to pause and when to continue when charging the low side so you're not feeding straight liquid with the compressor running. These units are great for DIY and are super budget friendly, but definitely not for professional use. If you're looking for professional grade equipment, you wouldn't be doing it on Amazon, right? LoL

Esta muy bonito, tiene buena caja de herramientas pero no es confiable las medidas que marca, ya que al desconectar el equipo de refrigeración de vería regresar a cero y no lo hace sigue marcando

Been using know for a bit great product doing everything I am needing it for just needs a bigger vac connection on them

Gauge itself is very good but hoses are cheap quality

Very impressed. Working as described.
