EZ Chill Car R-134a with Leak Sealer and UV Dye for Cars & Trucks & More, Red Dye, 10.25 Oz, RLS-3

seems to work fine

It's freon, the included hose does not stay on it well, fell off and also leaked. How do I know that? It has dye in it, which works well. Did not even need a UV light, the yellow fluorescent dye is very noticeable.​

Poorly made. I cant say anything about the refrigerant inside the can because I ended up throwing this away. The trigger isnt completely attached or sealed properly. Everything just falls apart and you have to hold the entire assembly together while trying to add the refrigerant to your car. The trigger keeps falling off and it is very loose. It leaks from the trigger and gets all over your hands and drips onto whatever surface is underneath the can. Its a huge mess. Stay away from this product. Might as well throw your 16 dollars on the floor. Whoever picks it up will at least put better use to it than you would have if you bought this product.

Small can but was very surprised it stopped the leak. The dye is very visible.

This was easy to use and will hopefully help my ac problems, but the connector is pretty cheesy, leaked a lot spilling UV dye over the inside of the engine compartment, making it hard to find actual leaks. I'm not sure what the red dye means, it's UV dye which glows bright blue under UV light, no red I can find.

Very easy to use. I really like the clear tube so you could see the refrigerant going into the vehicle

The design of the system is completely useless. After connecting to the A/C system the connection leaked and when the button was depressed to start the flow which I could not stop, it went everywhere it sprayed from both ends of hose, from under the button on can and and from around the top of the connector. The UV dye sprayed all over me and the engine, defeating the idea of checking for any leaks. DO NOT BUY This product. Spend the money and have it done by the professionals, you will end up there anyway and they will have to clean your engine compartment (extra cost) to look for leaks.

Convenient package however the hose is very short if your suction port is in a tight place.
