Leak Saver Leak Shot Dye Inject Kit - Complete UV Dye Refrigerant Leak Detection Kit for Automotive, Home, Commercial, Marine Air Conditioner, and Refrigeration Systems - Made in The USA

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.

Exceptionally good product.

Quick shipping, product as described.

Did the trick needed to add dye to system that didn't show a leak when pressurized this should do the trick to locate it.

Product page states "The Leak Saver injects directly and easily into the system with a basic manifold gauge set" which is not true with automotive systems. This information should be mentioned in the product page, especially if the product can't be returned. The $32 injector shot adapter is required, so having known that I would have bought the kit that included both and an LED light for a similar price. Now I can't even exchange this for the product I would have gotten had the page possessed pertinent information.Update: Customer service reached out and offered me an apology and a full refund which I greatly appreciated. Hopefully the product page will be updated soon to reflect the need for an adapter. I did end up purchasing the shot injector and it did work fairly well for injecting the dye. There was no spraying or leaking and it went in very quick. Only problem was I still couldn't find the leak, but it was still loosing charge within a few days. I followed the instructions and ran the system for an hour with a new charge but couldn't locate anything that glowed under UV on the system. Only thing left to check was the evaporator, which did have some glowing specs on it, but nothing definitive. The dye does glow brightly when exposed to UV light, so I'm not sure why I couldn't find anything on any of the parts. I can't say the dye doesn't work, the bottom of my hood glowed very bright after oil from the system sprayed on it during removal. I have another car that also needs AC love so hopefully I will have better results with it.

If you are in any way apprehensive about working on your A/C by yourself, DO NOT BUY THESE PRODUCTS.I purchased a tube of “Leak Saver Ultimate” last week for $48 bucks and then decided that to be sure I did the installation right, I purchased their injection kit for $60.I followed all the instructions ….watched the videos and attempted to inject it yesterday.The tube exploded!Scared the bejesus out of me…..and now I have no way of knowing how much…. if any ….was actually injected and how much was wasted out the burst tube.The real disappointment however, was that the company made no attempt whatsoever to respond to my email informing them of the incident. I even sent pics of everything so maybe they could narrow down the lot number to prevent it from happening to anyone else….no response.All their literature and instructions say how they are a Professional HVAC company and requests you contact them with any questions and concerns … don’t waste your time ….my suggestion is to save your money and look elsewhere.

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.

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