You have to keep in mind that it is pretty small, but it can start a fire in any suitable material as long as you have bright sunshine.

I used it to light a couple pieces of cardboard on fire it worked pretty well! But having to look at the bright blinding dot kind of sucks. Ive been trying to find something to fix that problem my sunglasses did not work. I want to try a pair of eclipse glasses.

You can't tell from the images, but it's not flat like other Fresnel Lenses I've used. It is covered in circular machining (?) ridges on one side. I'm guessing this design or poor machining is what results in the lens having a terrible focal point completely useless for starting fires on tinder. I would give it 1 star but am assuming amazon lied to me in my search and/or there are variations in Fresnel Lenses that I am unaware of.They've since updated their images to show the ridging. Apparently it is a valid design. With that said, I could not get it to focus how the pictures showed with clear sun overhead. For comparison, my wallet sized Fresnel Lens produced a better focal point so the 3 stars stand.
