Customer reviews:
Product is quite cheap, but the customer service of this company is amazing, so I have to give them at least 4 stars. 
 works grate. 
 Good quality at a low price 
 Good sturdy set of AC gauges. If you are gonna use them for 134A, you will need extra adapters, available on Amazon 
 works fine 
 Best for the price 
 Works well. If first time trying to service your system, make sure to understand that once you hook up the high pressure side, you will lose a significant amount of charge from your system because the hose will fill up with liquid refrigerant. 
 Works great, no leaks! You'll need to buy the R134a quick connectors separately. 
 Nice set, just as good as the high priced ones 
 As expected! 
 Worked perfect 
 Excelente 
 Best set period for the price just be sure to buy the adapters if using r134a
