Review on Pro ACP410 4 Hose Dispenser by Cristofer Cejudo

I kept adding refrigerant because I couldn't get the gauge I wanted! After adding a second can of refrigerant and disconnecting it from the car, I found that the AC was blowing warm air! I plugged it back in to test and found that the sensor is now showing an overflowing red zone! I was forced to probably empty all 2 bottles so the sensor readings were in the zone I was shooting in in the first place! Talk about $30 down the drain! I may have bought a faulty sensor!
