So far so good
Had a small leak. Bought it and followed the instructions.Tried to add gas, and didn’t see the PSI goes up, so I thought it didn’t work.When the summer arrived few month later, I saw that I have way too much gas. Had to take a lot off.This product actually worked perfectly (at least so far :)).I’m very happy with the results. Really recommended if you have small leak.

Time will tell but it so far it really works!
I have an 8 year old Mitsubishi mini split AC that developed a small leak in cooling coils (right after warranty was up) and was told parts weren't available and the current air handling (indoor) units were not compatible with my compressor unit. Frustrating for a name brand appliance to end up with such a short life span. Heard this would work on mini-splits and gave it a try. It's been some weeks now and it's still blowing very cold. Finger's crossed!
