I bought some really cheap headlight tint (same thing) and it's seems fine as long as you install it correctly. A lot of the brands selling it are just re-branding the cheap stuff and charging 10x the price, best bet for a professional job would be at a shop of course.

Good luck whatever you do.

Have you done your taillights also?

I was looking to do that. I don't want to use that nightshade stuff on my lights.
