As a science educator, I found this product very helpful in teaching optics concepts to my STUDENTS. Using this product our team found that it's easy to demonstrate the basic principles of light and the handling of light rays. The tools' durable build made it suitable for everyday use in the classroom and produces accurate results. However, the price is a bit higher than other optics products in the industrial and scientific market. Overall, I would recommend this product to anyone interested in engaging with science education..
