Review: happy with my science toy - I just got this yesterday. So far it has really exceeded my expectations. I did a science project with my son. It focuses light extremely well, it magnifies really well and clearly with no discernable distortions. It is light weight. If you want to do some science projects like solar heating or starting a fire it is great. This is for responsible teens and adults. It is awesome for sciency projects or if you want a "solar death ray". Safety first, this isn't a kid toy, it would be dangerous in sunlight, wear eye protection it is too bright to look when focusing sunlight on something that isn't jet black... but it works great.

### ⭐⭐⭐⭐⭐ It's a fresnel lense and a science learning opportunity
*by S***B on January 3, 2025*

Likes. First year I didn't buy gift cards. Adults and kids liked it. Fun and something to learn about. Magnifier for fun and start a fire for the survivalist. No one knew there was such a thing as a fesnal lense. Made of good, plastic, should last long time if taken care of. Well packaged. Nothing to dislike, just present as learning opportunity with a couple of demonstrations every one will be excited.
