## Customer Reviews

### ⭐⭐⭐ 







  
  
    Labeling OPEN and CLOSED incorrect and misleading.
  

*by J***E on Reviewed in the United States on June 8, 2020*

OPEN and CLOSE directions on top knob are incorrect. OPEN is clockwise , opening port on compressor side of fittings. Both high and low side fittings are labeled incorrectly. Turning the adjustment knob counterclockwise prior to connecting to compressor, allows you to keep the schrader valve closed on the compressor until you turn the adjustment knob clockwise , which opens the schrader on the compressor side, connecting your gauges to the compressor. Labeling implies the OPPOSITE!

### ⭐⭐⭐⭐⭐ 







  
  
    Worked like a charm, unlike other brand
  

*by S***N on Reviewed in the United States on September 11, 2019*

I had a gauge set (probably harbor freight) that had the r134 adapters on it. high side worked ok but low side just would not open schrader valve. My old ones looked just like these. I read other reviews of people having problems just like mine that was solved with this set, so I ordered them. Arrived quickly, put them on my gauge set, hooked it up to the RAV4, turned the valve on, and to my relief it worked perfectly. Now I can charge my system properly and troubleshoot the other car properly.Perfect.

    Got the job done right!
  

*by R***Y on Reviewed in the United States on July 21, 2018*

I'm a HVAC tech, and I have a standard set of manifold gauges. I'm glad i found this product because i was going to fork out $100 for new automotive manifold guages. They worked flawlessly, and would recommend.
