it didn't worked, I used this product in my Skoda Superb, 1.8 TSI car AC , in which the AC gas leaks in 22 to 24 days , but after using this product nothing changed. now also the gas leaked in 22 days

### ⭐⭐⭐⭐⭐ I am very Impressed!
*by L***Y on 4 August 2026*

I have a 13 year old 410a system that developed a "2wk" Evap leak at the beginning of the 88 - 95 degree weather so desperately I bought this with no real expectations to hopefully try and hold off for another month at least while I figure out the best way of purchasing a new system. Its been 4 months & multiple 3 digit days here in the south & all of our Gauge Readings have held up as well as Delta T & the Superheat recommended by the manufacturer....I'm VERY impressed & I honestly, in the beginning, felt like this would end up being more "snake oil". I'm a certified Universal 608 holder but I am an AMATEUR. I've heard claims of long term negative affects & even that its "idiotic" to use this in the first place. I couldn't verify any of that in this review because my experience in HVAC doesn't hold as much knowledge as a long time professional but I can say that in a very difficult financial situation this really worked for me and my family.
