Very good, for the price.

Like any instrument, it should be calibrated. I use table salt and an alcohol flame. I read the value of the sodium line from the scale and subtract 590 nm from it. The difference is the correction for the spectrometer. Thereafter, just add the correction to the scale reading to get an accurate result.
By far the best spectrometer for the price

It's meant for school experiments. It's plastic. It feels like a toy. But it's vastly better than all the other under $100 spectrometers on the market.
The original 1991 version had an adjustable scale so you could calibrate out any scale error. This one still mentions that on a sticker, but the scale is NOT adjustable.
Mine reads low by about 1.5 nanometers. You have to squint to use it; it's awkward.
But if you're careful you can read lines to the nearest 1 or 2 nanometers.
The EICO and all the other ones I've seen (I think I bought all of them) are worse. This one is not great, but it's by far the best for less than $100. Nothing else is even close.
