Well worth it. Great product.
Size: 1 Kit, Size: 1 Kit
For the inexpensive price it’s worth its weight in gold. I admittedly probably didn’t work on it as long or as hard as I should have, but I still had great results.
*** One warning: when it says to “tape up and cover your paint around it” do it! I figured I would just be careful but no I was wrong. It will REALLY damage your paint, so make sure you don’t get any on it. YES- This is the sanding discs too! They have chemicals on them, they are not regular discs. If you do get on paint, clean immediately! My only regret with this project and my fault, not theirs.
My headlights went from dingy yellow, to much brighter and definitely more clear. Love the results. Very happy with the purchase.

Great for the price

Worked great at clearing my headlights and at a great price, I had used a different headlight kit maybe 5-6 months before and it did not perform as good as this kit did, maybe it was a user error with the previous kit but this one cleared it easily and was very easy to do and had a nice clear shine.

I'm Not Disappointed ...
Size: 1 Kit, Size: 1 Kit
I knew going in that my expectations shouldn't be very high because my car is a first generation 2010 Kia Soul. So its old with 16 plus years of yellowing oxidation and some abrasion. I took a chance with doing this because of the reviews and pictures. To my surprise, it worked better than I anticipated and could hope for. My driver side(left) headlight was horrible but my passenger side(right) wasn't too shabby and didn't require as much care. This would have turned out better if I had power drill attachments of the same sanding grit to do this. My arm is going to be really sore come Sunday. 😆 It wasn't too hard to follow the instructions as they were very simple for the application process. I don't know about the 2 years for it lasting, but for now, its durable. Once I drive at night, I'll be able to
But all in all, it worked for me and its better than before I tackled it. All in all it looks good, I feel like I'll have a better beam when night 🌙 driving.
