Lo mejor. Los articulos muy bien.y en un tiempo recor..........

Great product but you should add sticker to packaging to identify that dye has been added to the system

After installing into my ac unit, I was able to find the leak(s) with a uv light.

Very good . Detects Freon leaks very easily

Edit: seller was prompt and went above and beyond handling my concern. I've also now used the other components of the kit to do a dye injection and it is super simple and clean. Will be inspecting for the leak this evening.Original: The dye and injection parts seem like high quality, but the flashlight is defective. Tried two sets of batteries, triple checked the assembly of itand cannot find any reason it shouldn't work. Wanted to contact seller but Amazon says no returns/exchanges on this due to the hazardous nature of it. Bought the kit trusting the light would be of high quality based on the Leak Saver's apparent pride in their product rather than just buying a random light off Amazon of unknown quality.

The product was easy enough to use. I tested it before putting it in the system and it certainly lights up when you hit it with the UV flashlight. It attached to the low side charging valve no problem, I hooked up the gauges, used a cylinder of refrigerant to push it into the system, all that worked as advertised. I let the system run for over an hour without stopping. But I still can't find the leak.

We injected the UV dye into our home AC using a manifold guage, and you could see when it got sucked out of the tube. Then the system ran for over an hour while I kept checking for evidence of the leak. When I opened up the air handler to look at the coil, there was a loud continuous hissing, indicating a leak. However I could not see any dye glowing with the UV light. Because of the hissing, we were convinced there was a leak in the coil, so we cut it out and found the leak on the back side which explains why we couldn't see the dye. Note that you need a black light to see the dye and the black light is not included.

I bought this several months ago and just tried to use it. It CANNOT be used on my car A/C system because the fittings are not standard size, they are too small. It CANNOT be connected from the freon bottle to the input line.They advertise an injector to shoot this into the system. that wouldn't work either as the fitting on the other end is also too small and cannot be used.This is a HUGE ripoff! DO NOT BUY THIS STUFF!
