Good

Good product for learning. I taught my son all ray diagrams of mirrors and got candle image on house wall. Better than wasting money on gamezones in mall. They should keep a small booklet in instructions or post online and put a QR link

Size is too small for experiment Glass finishing as well glass quality is very cheep. Grinding is also visible in covex lense. Glass slab is not very perfect it's light green color. It's should be perfect transparent and transparent color also. Prism is average quality and size is ok

The Kit consists: Concave Lens, Convex Lens, Concave Mirror, Convex Mirror with Focal Length of 20cms each. It also contains Glass Slab & Prism. This kit would definitely help students to learn themselves eagerly with simple guidance. They can able to understand the Physics (Light & Optics) with conceptual understanding, rather than Rote learning.

The concave lens is not at all transparent, it is hazy. Prism also was broken from the sides and has artifacts inside it. Lot of scratches on glass slab

I liked the product. My son uses it a lot
