Greentech Eco-Science 30X Cell Phone Microscope

still use today

I love love love this product! My daughter got me one at 5 below last Christmas and I have recommended this product to everyone who will listen since then! I have bought quite a few as gifts as well as for use in my science classroom. It is fun, easy enough for my 4 year old to use and explore and fun for my students to get excited about the world around them as well. It is also fairly durable. I am VERY pleased with this product!

Obviously considering its low cost this product isn't going to be a replacement for professional tool, but that said it does 30X very clearly and works as intended. The way its designed should fit most smart phones. I would highly recommend this as a gift for a kid.
