ZeroR® Permafrost for R1234YF AC Systems | Performance Booster | 5 Cans + 24" HD Can Tap Gauge

I thought our 2019 Subaru Forrester was not cooling enough. So I questioned my mechanic and he said it would cost $200 to do the check and probably another $300 to do a reinstall of the Freon. I decided that my best option was to try this product. I watched the YouTube video as to how to precisely hold the can attached the unit and how to adjust slowly let the product into the system not all at once to keep the pressures equal very helpful before installing I did use two cans, but probably wasted the second can about half of it. My temperatures out of the blower fans were about 55° before adding the Freon after the temperatures went down to about 39°. I have one happy wife now as her air conditioning is working as it was New.

I purchased **three cans** of this product, and unfortunately, all three appeared to contain only about **1/3 of the expected amount. My mechanic checked them and advised me that the cans had very little refrigerant in them and were essentially wasted. He explained that cans of refrigerant normally should not have such a small amount of product inside. I paid for three cans expecting to receive three properly filled products, and that is not what I received. I am **extremely disappointed with this purchase** and feel like I wasted my money. My mechanic recommended that I request a **full refund for all three cans. Based on my experience, I would **not recommend this product. I also reached out to the supplier directly, and they told me that each can only contains about 4 ounces, despite what I expected based on the container. In my opinion, that is extremely misleading and a complete rip-off. Imagine only getting 1/3 of a can & you order 3.!?

Everything worked out great, Will buy again if needed in the future

Effective, looked up method on YouTube, wasn't hard.

Self explanatory easy to use does exactly what it says it does.

WARNING!!! Stay away from this product! Once I received the product, I figured out this is not a refrigerant, is a kind of dangerous flammable substance. Nobody recommends this product to use for your car or truck!!! I ask for return and was charged over $17 for that

My $69.99 investment was well worth it to restore the cool temps to my 2021 Kia K5. Especially in comparison to paying a mechanic $150 or more.

The quality, condition, value, and appearance all exceeded my expectations everything was perfect.
