Review on Aupoko Injector Refrigerant R 134A Coupler by Cary Clemons

It was a waste of money. It arrived on time, but the manufacturing process resulted in a knot that did not jam the threads on the top cap of the canister body with hose attached. This made me so angry I didn't even want to speak to the seller and just decided never to do business with him again. Buy a function block for a few extra bucks because it could very well end up leaving a full can of paint in your customers engine bay or tool closet.
