I purchased this product because I had a coolant leak on a 2011 Ford F250 pick up gas truck just was ripping my hair out trying to find it this kit enabled me to find the leak which turned out to be in the heater core unfortunately, but without the kit, I would’ve never been able to find the leak and I couldn’t have been more happy with what I received it’s a very good quality kit. It comes with everything you need to start your leak search on air conditioning, oil and coolant, leaks which is what I was working on. And honestly I was your truly impressed. I did see a review about the light, but I haven’t used it i already had my own uv light but you still are getting one in the kit and that’s nice and there’s room for your own light for the future as the box they give you has enough room it’s not too big, but it’s big enough. You can add more die if you need the die injection for the AC is really good quality it’s made of aluminum haven’t used it yet but compared to once I’ve used in the past it really seems good quality look forward to using it in the summer. The box that you get is made of plastic would be a good upgrade for a shop, but it’s good quality, and honestly we don’t take these kits out very often in the shop so I think it would hold up now if you’re going to use it a lot I would recommend upgrading to a metal kit but I don’t think you would have to only recommendation if you’re going to use it a lot the dies are fantastic. I’ve only used the coolest tie so far but this is what I’ve observed it washes away with water. It doesn’t stain and if the rest of them are this way, I’ll really be impressed. Most UV dyes are not like that truly impressed me when I found that out. The only thing I would recommend to the manufacture , and this is just me I’m a stickler for instructions and I think I used too much dye when I put it in the coolant. It’s just a little better instructions on the bottle but they’re pretty simple as they are. I couldn’t recommend this kit anymore. It’s truly fantastic highly recommend five stars, they couldn’t make a better kit. There is ways to improve it, but it would just raise the cost so truly well done, I have no negative review you will not find anything better for the money

The kit came in a nice case and presented well, but the UV light broke on day 1. I had to purchase another UV light to replace it.
