    So far so good =)

    I put this in my car about a week and a half ago and the A/C is holding up just fine. After several dye tests and checkups by others, whom could never give me a straight answer about the exact problem, I took a leap of faith and purchased this for $30 and it hasn't let me down yet. A $30 dollar investment into something that might work is better than hundreds of dollars replacing A/C parts.
    I cannot stress enough how important it is to follow the directions with this product. Be sure you car is running and the A/C is on max power. Also be sure to put refrigerant in immediately after the Stop Leak. It's important that you get all of the fluid moving through the system and this could take up to a half and hour or so, so be patient.
    I would definitely suggest this product to anyone looking for a solution to A/C troubles.

    Pros: Stopped what ever leak I had and is holding up nicely

    Do not buy. I wasted 70 dollars on this and air conditioner coolant. Does not even remotely work.

    Pros: none/ waste of money

    Cons: does not even seal a small pinhole.

    Don't waste your money on this product. It is expensive and it did not seal a leak in a sensor fitting.

    Pros: None

    Cons: Too expensive & doesn't work.

    Just don't waste your money. Use the dye and find the leak. Will not fix compressor leaking. That part you just have to replace it and that's the money part.

    Pros: none

    Cons: don't work
