Overall:

BG252349201 07/01/2022

For the price its good, For educational at young age. The plastic holder will be the weak link,pun intended. With some cardboard you can see differences between spectrum of various emitters, sun, led, laser(pointer) intrc. Might be more practical if you take just the prism ... you will be able to guess the wavelength when using a webcam as detector . was delivered in time and without damage was reasonably packed.
