The design is very ingenious, but correct assembly would be a little easier if the instructions were more precise, particularly with the mounting of the black strip to the relevant flaps, and the positioning of the diffraction grating. Since the grating supplied is rectangular it would be easy to state the orientation required to have the lines parallel with the light-slot, rather than leaving it to trial and error. However, overall it is a very impressive instrument for the price.

Very precise spectroscope, I used it while teaching and compared with a more sophisticated spectroscope, the difference never excede 5 nm.

A bit smaller and more fragile than I expected, but it works well.

I was expecting something more than a cutaway.

Works well, and is fun to use.

Seems good, I've cut it out, but have not completed assembly or used it yet.

A very simple, but clever piece of kit. Mine has just been to the Middle East to use in teacher training and created a lot of interest.

I did not like the quality of the material, it was ackward to assemble and overall I was disappointed. BUT.................. I have also to say that the price was cheap, so in that respect I could not expect to much. I would rather have much more expensive unit which does it's job.

Very expensive and hard to construct.

Spectroscope case made of cardboard and not really robust enough. Plastic would have been better.
