kutuhal science of light. do-it-yourself experiment kit. collection of activities to learn science of light.- Multi color

Product is good for kids of 13 to 16 years. It has all components for various type of light experiments. Best product in the price range.

Good to introduce practical to young minds.

Extremely poor quality product. Once again it is proven that Amazon doesn't check the quality of items that sold by them.

Though it has lots of items for the experiment, the quality is poor. Laser light didn't work. Prism has air bubbles.

Good product but concave mirror convex mirror are not present.

Good product. Items are not of high quality but they are very helpful to clear principles of light.

It has no concave , convex mirror and lens it has no glass slab only it has plain mirrors. I am very dissapointed by this product ...It has written that it has concavs mirror and lens but it has not😡😠

Good for the price.. my daughter enjoyed it..
