ZeroR® AC Refrigerant | R134a Replacement | 2 6oz Cans for AC Recharging + 24" HD Can Tap Gauge

I filled it up with one cylinder. Everything worked. I haven't seen any freon leaks yet. But if you have a leak, don't try to do it all the time because in addition to coolant, oil also circulates in the system. Then don't finish your air conditioner, and the only way is to go to the specialists. P.S. The can is disposable, something left in the trash can is because the valve doesn't close the freon leak. You should wear glasses and gloves.

Worked well and easy for 2017 Audi A4 Quattro. The only thing is that you can not close the can that you didn't use completely.

I was disappointed with my purchase, as the product did not meet expectations and, to add to frustration, I had to pay out of pocket for the return shipping. It's frustrating when a product underperforms and the return process becomes an additional inconvenience. You have to pay extra shipping since the product is hazards materials. At the seller end after return, there is a charge of "50%-100%" restocking fee.

I am a female it was easy for me to do it by myself by looking on YouTube. I only used one can my car got cold with the use of 1 I will use the other can when needed. It fit my car great No leakage the build quality was great for my car

The gas worked good. Only problem was the fill line kept leaking out gas when the valve was closed.

It was good and worked for me.

It seems can’t be saved the rest of them due to keep coming out.

I was leary because of various advertisements that worn against using this But after communicating with the manufacturer, it's totally compatible, and they provide much more detailed instructions on how to use it than you'll see online.
