Is Halo Lytt safe for a child to wear?

Halo Lytt is sub-22 grams, screenless, and made from skin-safe materials. It is CE, FCC and RoHS certified, the same standards required for consumer electronics sold in Europe.

Those are not marketing terms. FCC equipment authorisation governs radio-frequency emissions in the United States, CE marking covers EU health and safety requirements, and RoHS restricts hazardous substances such as lead and cadmium in electronics.

There is also no screen, no notifications and nothing on the wrist pulling at a child's attention.
