How is it different from a regular heating pad?

It runs on a rechargeable magnetic battery instead of a cord, so you can wear it while moving around. It also adds 660nm red and 850/940nm near-infrared LEDs alongside the heat.

How long does the battery last?

Runtime depends on the heat level you choose; the top setting drains the battery fastest. Expect shorter sessions at high heat and longer ones at low heat.

Can I wear it under clothing?

Yes. The slim Lycra wrap and adjustable fit are designed for discreet wear under clothes, though the battery adds some bulk.

Which body areas does it fit?

It is shaped for the lower back, abdomen and waist. It is not designed for shoulders, knees or feet.

Does the red light do anything on its own?

The LEDs are meant to work alongside the heat, and their output is modest compared with a dedicated red light panel. Treat the light as a supplement to the warmth.
