Great fix

I was having issues with a leak in my 08 Camry, followed the instructions and let the car run for about 20-30 minutes before putting in freon. It’s blowing ice cold now and has been working strong for about a week now. Worth the price.

Not easy to use

Terrible instructions only on the box, my cars low side port is r134a but could not get the adapter on. Had to cut part of it to get the dye through the syringe and it never mentioned that

WORKS 100% 👍🏻

“Every 2/3 months I had this issue where there was a certain amount of refrigerant missing in my ac and it was not working properly. I had to recharge my ac everytime and it was causing me a lot of stress and money.Since I injected this product I have no more issues.I will for sure buy again the product in the future. Recommended “
