A:Answer Due to California state law, all our products are required to feature a Prop 65 warning. The notice is there due to trace amounts of metals found within the circuit boards of the unit. Users do not come into contact with the internal circuitry of the device unless they attempt to disassemble it (which would also void the manufacturer's warranty). This disclosure does not necessarily mean our products are harmful to customers' health, but serve as a disclaimer for all items. This warning affects all products sold or distributed in California, including electronic items and can be considered a consumer "right-to-know" law that informs customers if chemicals are present in the product or packaging.
