    After checking its operation, what I did not like is if you put rechargeable batteries instead of alkaline, the laser light decreases considerably.

    Lens kit is OK. The construction quality of the laser kit is poor.

    Lens kit is OK. The construction quality of the laser kit is poor. (so fewer stars on quality). One laser faded off within few minutes of operation followed by the others. The laser diodes may not be of the same quality and maybe one needs a higher voltage bias. Anyway, that's a sign of bad quality. It can be used to demonstrate the properties of light. provides value for the price.

    kids enjoyed the experience , having first hand on these optics they even dressed up in white Coates. don’t miss buying protective glasses like I did. important specially for the kids they love to try everything on each other.

    That´s a good deal

    It could be of better quality, but, it´s enought for students needs. This kit will improve my child learning in optical physics. It gets arrived in great shape, nothing out of order! Good price, good kit! Great!

    Idea is very nice. Good kit for the study of optics. I have taken one star away from quality and price because of packing box which is made of hard board instead of plastic (which I was considering at the time when I placed the order), moreover the manual is not in English.

    Interesting experience box

    It's a nice experience box to use with kids. The laser box sends a bright beam that is to wide in height. The laser spreads around when you want it to focus on the mirrors and lens. Everything is included except a manual in English, only Chinese.
