Beat 2 other brands hands down.
Had tried 2 other kinds of stop leak from O'Reilly's. This one is still holding so far. It seemed to seal much quicker too, as previously I'd noticed it hard to build pressure in the system. With this, the next can of refrigerant I put in, I only needed half a can! Previously 2 cans wouldn't get it to that pressure level. I'm planning on trading this car in soon because of other issues, but I feel confident this stop leak may last.Verified purchase: YesCondition: New

Works on several issues but there is always going to be a few cases in which it does not work.
Is definitely worth a try , instead of paying those high cost charges to repair the a/c system correctly. I had a highside Inverted Schrader valve that was leaking And gave this a try but didn't work for me so I had to purchase the complete highside line with the builtin valve...Good luck to all.Verified purchase: YesCondition: New

Old AC? Give this a try first.
It is very easy to use this stop leak. Hook it up to the right fitting (it will only go on the correct one) and push the button. My only complaint is that the button on top is hard to press, harder than the freon bottle I used after using the stop leak. Took a while to get it all in, but I was able to empty the bottle. I have a 2003 pickup and the AC was beginning to lose its cool. My wife complained that it was too hot in the truck (what do you expect from a black truck in the south?) Although the AC would cool, it wasn't really cold, and it took forever to really start cooling. I had topped it off with freon last summer but over the year, I guess it had lost some of the freon. I put in the stop leak, drove around the block, came back and topped off the AC with a full can of freon. Now, it's cold in seconds and my wife will again ride in the truck with me. It's been a couple of weeks and no loss of cooling, so I'm hoping the stop leak plugged up whatever was leaking and the freon will stay put. Even it it doesn't, it's cheap enough to top it off again if necessary. Thanks!Verified purchase: YesCondition: New

ac fix at a bargain
Very straight forward product, easy to use, just make sure your ac is low enough on freon so this will be allowed to be injected into the suction side in its entirety. So far my ac is blowing cold, even though i had to top it off with about 1/2 can of 134a..Verified purchase: YesCondition: New

GREAT PRODUCT!
After trying several other products unsuccessfully, this one fixed my main vehicle's A/C with NO problems. Its Awesome! I would even recommend buying an extra bottle or two. Just today I rebuilt and re-gassed an AC unit another vehicle and wished I had a bottle of Red Angel on standby just in case it started to leak over time. Wud DEFINITELY use it over other brands.Verified purchase: YesCondition: New

Fix the Problem
I'm my case the compressor was leaking, so this product didn't solve my problem. I dare not give it a negative review simply because it didn't work for me. I've learned that it's better and less expensive to fix it right and be done with it.Verified purchase: YesCondition: New

Easy to use
Used this product because I had a slow leak on my motor home a/c. My a/c started working properly as soon as I installed Red Angel stop leak. Will use it on any vehicle that has a problem with leaking refrigerant.Verified purchase: YesCondition: New
