I would suggest that if you’re considering paying this much for a product, you have a more serious issue and need to replace some parts. Did not seal the leak in my vehicle, wound up finding and repairing the leaking part so this was a waste of time and money.

I've got a slow leak somewhere on my 16 year old r410a 3ton Lennox Hvac - losing about 2lb of refrigerant over 8 months or so.Decided to try this leak saver as a last ditch hail Mary before biting the bullet and replacing the system. Used the charge in with refrigerant method - tube was clear and it was in in a couple of seconds, very simple. Left the tube attached while I topped up the rest of the refrigerant to the correct level. System is currently running great again, heating and cooling as it should. It's only been 3 weeks and given the leak is very slow before it becomes noticeable, it might be a while before I can tell if this has worked or not. I have shined my UV light round the usual suspect leak spots....have not seen any dye. Will check back in in a few months to see how it's doing, fingers crossed at this point!

I have a beverage cooler under my counter. The original started leaking after two years, and eventually I tried adding a leak fixer. It seized the compressor...So I bought another. After two years it started leaking. Eventually it lost cooling after two days. I tore it apart and found where dissimilar metal joints had ruptured. I epoxied a cocoon around the cracks, but could see small bubbles of Freon piercing the epoxy seals.After epoxying, the fridge would hold Freon for just exactly a week before needing a recharge, which is the time frame this product says it will fix.Having read up on-line, I realized that a leak fixer responds to humidity to create a seal, and so the seizing of my original unit was due to water in the Freon!Ok, an expensive lesson learned. Then I found that drying agents were available, but not in packages designed for small appliances, but rather for huge A/C systems!Except for this product!!!!! Specifically designed and packaged for small refrigeration units.This product is absolutely brilliant. Exactly what I needed at a very reasonable price and packaged so that it was a no-brainer to hook up and use. It came with a short adapter hose, and just simply hooked up and was easily injected into my Fridge.We're three weeks and counting! No seize up, no recharge. This product is saving me over $500.00 every two years!Not often that I come upon a truly excellent product. This is definitely one of them. Thank You!

I think it worked on my $2000+ dollar refrigerator. After a week the freezer still holds temp at 8 degrees and fridge at 40 degrees F. It was a 134a refrigerant system. It seemed to be a very straightforward install system but there is a catch. I setup as recommended using the refrigerant to force the stop leak into the system. No matter what I did I couldn't get it to inject into the fridge. After trying at least ten times to get tech support on the phone I decided to investigate the issue myself. The tube has a Schrader valve on both ends??? (Schrader valve is like the valve on your car tires to let air in or out) I guess it is to hold the stuff in the tube. After looking further, I found there is a spring loaded movement in the fridge end of the application tube that is supposed to actuate a bypass for the Schrader valve. It didn't work on my piercing valve. So I removed the Schrader and carefully keeping the open end up so it wouldn't pour out, attached it to the piercing valve and "Voila" it worked instantly. I did have to recharge it after 2 days, but I felt that the initial charge I put in was weak in the first place. Seems to be working well now.Note: I did hear back in an email from tech support with good information that confirmed my assumptions about the Schrader valve. But my time is important to me, and if the directions just had a simple set of directions about what to do if it won't go into the piercing valve it would have saved me 4 hours of frustration and loss of time, for a task that should have taken no more than 15 minutes. Their website says nothing about this in the tech support page either and I believe it is likely a common issue.OVERALL: Good product; good price; poor instructions, poor website for tech support info.
