Review on Aupoko Refrigerant Charging Condition Maintenance by Jerry Stewart

This refrigerant charging tool is perfect for automotive air conditioning repairs. It's easy to use, and the clear hose allows me to see the refrigerant flow. The compact size of this tool makes it easy to carry in my toolbox, and it's made with high-quality materials that are built to last. The only downside is that it can only be used for R134a refrigerant, but this is a minor issue compared to its overall performance.
