Will save you a ton of money in many cases.
Great product. I've been able to fix a small leak in our house ac system... I was having to add R22 to the house every 3 months or so. Its been a year and its still working great. Also, I've used the smaller vials to fix several vehicles at my auto repair shop. Its fixed 3 and a 4th the leak was to large for the stop leak to work, but the dye told me exactly what to replace.

Fourth time I bought this.
Every single mini split I had seems to leak a tiny little bit from somewhere. It's getting to the point when I install one of these I just shoot it in for preventative maintenance. I have rental houses with these units in there. If you have a leak that takes half a year to leak this will seal it no problem. If you're freon comes out in a couple days this will not help. It's literally for small leaks. For instance you have a small coil leak that you can't find or perhaps the fittings are leaking. The seals it. Been using this for years and I've never had to put a second shot in anytime. I did accidentally shoot it all over the yard when I bumped the valve on my freon gauges and that ticked me off but that was my own fault. Make sure you follow the directions on how to put it in and you will love this product. I would use again and again but I hope I don't have to.

Cannot seal even a micro leak.
Money is wasted. I own an appliance repair business and tried this several times. They say this product can seal any leak that takes more than seven days to leak all refrigerant. But every time I used this the system lost the refrigerant within two months. Do not recommend.
