Comprehensive FAQ for DistributorsQ: How does the Air Bag massage differ from Vibration? A: Vibration stimulates nerves and relaxes muscles via shaking. Air Bag Massage physically compresses the tissue, mimicking a human hand squeezing the knee. This is superior for improving blood circulation and reducing fluid retention (edema).Q: Is the 10W power consumption high? A: 10W is a high-performance rating, ensuring the air pump is strong enough to provide effective compression and the heating is rapid. The 2400mAh battery is perfectly balanced to support this power for multiple sessions. Q: Does it fit all leg sizes? A: Yes, it utilizes a 3D Wrap Around design with Velcro fastening. It is adjustable to fit various leg circumferences securely without slipping, even while walking. Q: What is the “157g” weight claim? A: The core structural design is ultra-lightweight, with the main unit designed to be as light as 157g (comparable to an apple), ensuring zero burden during extended wear, unlike heavy, bulky traditional massagers.9.
