It shows a lack of flexibility in adjusting LED, they operate almost in all or nothing. The total power is low (or camera lacks sensitivity). The cable does not allow easy guidance. The development is deplorable, autofocus almost nonexistent: the focus is clearly about 5 cm (say from 4 to 10), even in good lighting. Manual adjustment would have been desirable. So yes as electronic magnifier (detailed observation of the weave of a fabric), not as an observation system behind panel bathtub.
