Worked
Worked great on the 2018 traverse that seemed to have a pinhole leak that I had to fill once a year. But after putting this 2 years ago I haven’t had to add anymore. So hopefully continues to hold.

Seems to work (2015 Evoque)
I have been filling my a/c with Freon every 2 months and had also tried Freon with stop leak in the formula to no avail. So I decided to try this product as it seems to be a more effective treatment. Fill the system to the recommended fill (had a separate gauge for that) and it actually made my a/c colder! Keep in mind the system already had Freon, but was running out. In fact I had bought actual Freon to fill in after the Pro Seal, but didn’t use it. I will update 2 months out (which explains my 4 stars) but so far I am impressed. Update 11/18/23 My A/C is still going strong. If you follow the instructions as indicated on the product, it will work effectively! Five Star rating on this product.

No gauge saying how much is full
Not clear if this is for car or other AC units. There is no gauge indicating how much is being filled up like you would get with other proseals.
