DAVID A.: Works great

SY: After reading other reviews about sealing the possible AC leaks. I decided to purchase it. But after using it as instructed and refilled with new freon. It only lasted me about 4 weeks and no more AC.

Johnny I: Did not work for me drove for an hour after putting it in I had holes in the condenser welds

Lee MazzarellaLee Mazzarella: Worst product ever. Before you think I'm a noob or don't have a clue, I've been servicing cars professionally for 35 years. I had just replaced an A/C from the compressor to the condenser and everything it between. After putting the system on vacuum for 2 hours I usually let it sit for about a half hour or so to check for leaks. After everything checks out I let the car idle until normal operating temperature and start to fill the system to manufacture specs leaving room for a seal sealer as preventative maintenance. I do caot all the O rings with oil but enjoy a little peace of mind having something circulating through the system. Following the directions on the can, absolutely nothing worked. Would not seal to the port. (All R-135A low pressure ports are the same) depressing the trigger on top of the can didn't work either. Have to push on an angel from the corner and then it's hit or miss until the nozzle pops off. Center of the button is a no go. As for the quality of the contents, I'll never know because it can't be used. The small bearings that are supposed to lock onto the port are too depressed to lock and don't pop out to hold no matter what position the spring loaded...

Winter B: Shipping was super late, even Amazon felt it was late. Put the whole can in, drive for 15min. That’s it. Did not work. Wasted 90dollars. I will not recommend this product. Go get the 25 dollar Canadian tire leak pro. Those last longer

Abdul A.: I used this product in my 2014 Subaru Outback and it worked. Before to use it, every time that I filled the system with a gas can, it took around 5 days to go empty the system. After I filled the system with this product, the AA blowed cold air during 5 weeks until I sold my car.

noblefable: I rarely write reviews, but this is worth writing about. For starters, I am not an auto mechanic. However, based on my education and job I know more about A/C than the average consumer. Keep a few things in mind… almost all of the vehicle A/C refrigerant piping and coils are out of sight. So seeing a leak while looking under the hood is not likely going to happen. Also, you don’t know if you have 1 leak or 25 leaks (or zero leaks because the real problem is something else) or how large each leak is, so using this product (which costs less than filling your tank with gas) requires taking a leap of faith. I used it on a 2013 model year car that I would not be willing to put major $ into for fixing the A/C. I have an A/C refrigerant gauge set, and I had zero pressure on low and high side. I added a good part of a 12 oz can of R134a and once enough was in the system the compressor engaged. If the compressor won’t engage when adding a decent amount of R134a, then there is no point using this leak fixer product because that is not the main problem, and leaks may not be a problem at all. My car A/C system only held the R134a for about 1 day, before back to zero pressure. That rate...

DJ: If you're buying this, you're trying to save some money vs a proper repair. It may or may not work out for you. Buy it knowing it may not work, but if it does work it could save you $$. So make your own assessment.
I have read hundreds of comments, here's the summary that could save you some time:
5/4 stars - worked for me / may have worked for me
3 stars - seemed to work for a bit but lost A/C after X weeks
1-2 stars - Didn't work for me, and/or the connection and/or can leaked and I lost all the product.
Ok - my experience - shake the can. Remove thin tab from top of can. Turn on car (10 yr old odyssey with very small A/C leak) and A/C full blast. Connect can via collar connector to low pressure A/C port. Depress trigger on can. Observe substance flowing into the port. Lost some product (20-30%) from the connection at the low pressure port. TIP - keep your hand on this connection and you will lose less product. Gently - gently - wiggle the can as you depress trigger. Did this for about 2 min. The top part of the can popped off twice (didn't lose product, was able to pop the top back on and keep going). Drove the car for 15 minutes with A/C full blast. A/C worked...

proxyproxy: After watching ChrisFix on Youtube, I was inspired to try and fix my AC on a 2007 Accord. First, I had to determine if a leak was the cause of my AC woes. I purchased an AC gauge and used it determine what my pressures where. I found that my pressures were extremely low compared to the Honda maintenance guide so I added some UV dye and r134a so the compressor would circulate the dye. I purchased an inexpensive UV flashlight from Home Depot and didn't see a leak. After a couple of days of using the AC, I went back under the hood and noticed a leak on the high pressure tubing coming off the compressor. It was leaking from the crimp that transitions the aluminum tubing to the flexible rubber hose as indicated in the photo on the right. The leak continued to grow so I decided to add the Red Angel and slowly added r134a to the prescribed pressure level while checking the blower temperature. Over pressurizing the system can damage the system, so I wanted to be very careful. I found Red Angel after researching various forums and found great reviews. I didn't want a product that would harm other components that would be really expensive to replace so this seemed like the most conservative...
