Ive had my car’s air conditioning checked twice in 6 months because the gas leaks out slowly but they couldn’t find the leak. Instructions said to use this and then gas up the AC, but I had gassed up my AC first (2 weeks earlier) then ordered and used this; still worked great! 3 months later and my AC is still cool!

I tried using this on a 2017 BMW 540 that needed to have it's A/C recharged twice last summer. The quick connector that attaches to the low pressure port seems really cheaply made (it's plastic) and is difficult to attach. I thought that it was broken but eventually got it on... I think. One tip is to try to rotate the connector and try different positions on the low pressure port. Another tip is that your A/C compressure MUST BE RUNNING! I had to add just a little bit of refrigerant til my compressor kicked on, then I added the stop leak, then I added the rest of the refrigerant. Since there's only 1oz of product, it's difficult to determine how much product goes in or should still remain in the tube. The directions could use some clarification. However, I believe that some product did make it in, but only time will tell.
