Works great,not for heavy oxidation
This stuff works great, but it's best to grab (Awesome) spray, to use as a first step. The yellow oxidation melts away on contact, then rinse your headlights thoroughly with water and micro rag dry. Then use the wipes that come in the box to clean the headlights thoroughly again, rinse with water. Once thoroughly rinsed and dried, apply the UV clear coat with simple left to right or right to left strokes. Let it dry and enjoy.

Good for the effort and price.
This will _NOT_ make your lights look brand new! It will make them clear again. Or mostly clear if your lights are super bad. I had one old light and one new light on my car when I bought it. It drove me crazy walking by my car. I used this exactly per instructions other than I rubbed the crap out of my light. I got great results! Not perfect though. I got two clear headlights now. That is what I wanted. The finish is a little rough. This is to be EXPECTED since you are not using buffing compound. Use gloves. The finish looks like a light is a few years old now instead of 15 years old. It will not be can not make your light look new. Get the expensive kit if you want new look. My lights look close enough to not catch the eye. I am satisfied.

Not bad at all!
These headlight cleaner wipes worked far better than I thought they would. I have used many a headlight cleaner and restorer, but this kit was the easiest to use with very good results. No need for power tools or even different sanding disks. Just two different types of wipes, super easy. We will see how long the lights stay clear for, but if I had to do it once a year it would be worth it! Four stars because the lights came out clear, but not crystal clear, but to be fair that may just be the condition of my headlights. Try this least expensive, easy fix first. It many very well be just what you need.

Worth it for $12.
Three stars for the progress it made on the lights of our 9 year old car. It works, but it won't look like new. Requires a bit of elbow grease, and it feels like a waste when the wipes run dry pretty fast. You have to keep them folded small (per the instructions) so they don't evaporate too fast, but then you get a tiny cleaning surface area as well. Spoiler alert: They still dry out fast.
I wish I'd taken pictures for you because you WILL see a good improvement. Just don't expect brand new look. I'd say we had a maybe 75% improvement, and that combined with the new headlamps we installed made them work great. 4 stars if they want to come back and offer a like 2-4oz bottle of the chemical they use on the wipes and just let me use my own microfiber. That would be great.

Product doesn't work as advertised
This product does not provide enough wipes to remove more than the minimum amount of oxidation. The headlights were starting to yellow, so the oxidation was not severe. We followed the directions on the box to the letter and after using the wipes as directed were left with a sticky residue (which was left-over oxidation that the drying wipes could not remove). I am forced to purchase another box of the product in order to complete the job. I can't drive my car around with the tape protecting the body of the car on it, plus this is Florida so there would be bugs stuck in the tape and the sticky residue. A terrible product. Plus when I called them they said they would send me an email so I can tell them what the problem is and they would give it to their "research" staff to handle. I'm doing that and perhaps they will reimburse me for the second box I will have to get overnighted in order to finish the job.
