Q: “Will we feel pain when microcurrent (weak current) flows through? ”

Microcurrent is a type of weak current similar to the "bioelectric current" that naturally flows through the human body. Because it is extremely weak, it is almost imperceptible. The closer you are to the shower panel, the stronger the microcurrent. When using the "HIHO Microcurrent Mode," please bring the showerhead close to your body (within 5.91 inches).

Q: “Do we need to charge or pay for electricity for the microcurrent mode?”

No, because its design uses hydropower to generate microcurrent, there is no need to charge it or incur any electricity costs.

Q: “Can anyone use it?”

Yes. It can also be used for bathing childrens. However, do not use the "HIHO Microcurrent Mode" if you have any of the following conditions, as the "HIHO Microcurrent Mode" generates microcurrent (weak current). If you have any concerns, consult your doctor before use, or use modes other than the "HIHO Microcurrent Mode."
