It is good value and

Works perfectly and i found the leak with it.

I also bought a pair of those yellow UV goggles, but I didn't need them! This dye easily shows up in a moderately dark room with a UV light. It helped me get to the bottom of where my oil leak was -- the snowblower oil drain pipe nut - and where it wasn't - not the crankcase seal. Yahoo! It showed me where the problem was and that made it easy to fix.

Description says suppose to be orange tint which it was not it was green which made it really hard to lin point a leak as everything shows up green under uv light on my car which is why i needed the orange

Used it to find a leak.

I recently bought an ol' hoopty truck and I knew there was a coolant leak somewhere since I could smell it every time I drove. No overheating or anything luckily. I picked some of this up and plopped it into the radiator, then drove it a couple times over the next few days. I also made sure to cycle the heat on to get it through the heater core. Was able to easily see all the leaks even in daylight with a little UV flashlight. Now that I know exactly what is bad, I'll be replacing the entire radiator soon instead of a bunch of hoses and other nonsense that's still good.

It worked for a P/S leak I was trying to find. But after I was done, the bottle cap leaks and makes a mess.
