Muy didáctico y sencillo de usar.

very cheap

I bought three sets of these for my 7th grade students to explore light waves. At first I was disappointed that some of the lights shot off to the side but then my students pointed out the knows on the top allow you to reset the light direction. It was a great demonstration for them how light can be bent as it moves through different mediums.

Lights are not parallel.

Each laser line generator can be smoothly adjusted, so that the resulting 3 lines will be equally spaced. That is important when demonstrating ray traces of various optical devices.

Each laser pack has 3 beams but both of my sets only the outside beams worked. The middle beams wouldn't work. My students were still able to see the light wave interacting and refracting or reflecting.

Simple yet powerful, easy to use, great for classroom

This looks like a fine set, but I had to go online to find a video in order to learn what all the parts were. All of the labels and instructions are in Chinese, but that was never mentioned in the posting.
