The Product Systems Behind the KD3802
Four product systems define the KD3802 platform and the checks buyers should prioritize during sample approval.

RP Microcurrent Control
Five selectable levels provide a clear basis for checking control response and operating consistency.

Elastic Metal Massage Teeth
The elastic metal teeth are central to scalp contact, operating feel and the product's differentiated structure.
Liquid Reservoir Structure
The reservoir supports the use of project-approved compatible liquids. Formula, volume and compatibility require confirmation.
