Query: Cool air again!

The hose is a little short, for the 2002 Impala I recharged. After I worked out the angles the product worked very well. I had no problem on the recharge and followed the instructions on the can. What I did find is that even though my AC was blowing cool air before the charge, 19oz's wasn't enough to fully charge the system. When I tried to purchase a refill can, it seems that it is only sold with the dispensing hose and gauge. I ended up purchasing an additional two 12 oz cans at a local store to finish the job. The dispensing hose did fit the R134a cans I bought and operated properly. I'm very happy with the product.
