This kind of makes sense in a strange way. Inexpensive red LED's have relatively narrow spectral line half width (~20nm) and you can set detection thresholds against measured values. This is much better than "I think I saw something in a dimly lit bathroom". This means that in the readout part (UI) it is hard to get wrong results ("Is it one or two?").
Then again it is a wasteful and overpriced product that can leave wrong impression of superiority to the customer.
- jsymolon 6y ago> it is a wasteful On one hand, what a marvelous thing it is. On the other, what a waste, single use of silicon, battery and LCD that'll go straight to the landfill.
