Jesse McCollum: I bought it and used it as soon as it was delivered. Works great. I would definitely recommend it for the slow leaks that are hard to find. The only downside to this kit is the light gets super hot, almost to hot to handle. The light has a really long cord for leaks inside or under your car.

Don: Can’t tell you too much about this kit not used yet but had the use of simuler kit and was happy with finding leak results

Roman Levandovsky: The kit is set up to test for different kind of leaks. It worked really well. The UV light flashlight is very durable and well built. The only thing that’s not clear from the instructions is what dye to use for power steering fluid (it’s the oil one) and how much to put in. I poured half the little bottle and it’s more than plenty! Probably should have went with 1/4 or 1/8th of the bottle. You don’t even need the special glasses with the amount of fluid I used ;). I found my leak, it was a small hose clamp, saved myself $2500 worth of mechanical work. So definitely worth it.

DC: The light could be a little brighter and the oil dye is not as bright under the light as some others I have used with this kit. Overall, though, a good kit and VERY useful.

Ethan Miller: The media could not be loaded.  This is a great set and the price is below $60 bucks. It is pretty straight forward and has usage label for each dye. If the dye happens to be same color as your coolant just go to local auto shop and buy alternate color. Do not put anything in your engine gas coolant or engine oil that is not recommended for the car. If you are not mechanically inclined leave it to the professionals. That said if you are buying this it is because you want to do it yourself. The kit works and you will be able to service cars a few times the best part of this kit is the UV light that connects right onto the battery. This means you never have to buy batteries and the cord is very long so you can see all over the engine. The kit comes with everything you see in the video and the major set back is to not have a case. The more expensive kits come with carrying case but...

TSG: I've seen people take stars away from a product because they're dumb, and as much as I want to take stars away from this product for not working, the fact is I'm dumb, and that's the source of my disappointment.

After doing some research, I went with this kit because the light is powered directly by the car battery. I read numerous reports of "cordless" battery operated lights not being bright enough or killing their own batteries quickly. Not a problem here - the light works great. It is worth the price of admission for this kit.

I bought the kit to diagnose a coolant leak on my Jaguar, so the coolant dye is the only dye I've tried - take that for what you will. And it's the coolant dye that is the source of my frustration. In the first, the coolant dye that comes with this kit is an orange or yellow color, which happens to be almost the same color as dried up Dexcool. I found several false positives (dried Dexcool) before I learned to tell the subtle difference between that and a fresh leak (the dye). I should have known that dye comes in other colors, and bought a different color to start with. Duh, my bad. Secondly, this dye is SERIOUS BUSINESS....
