Does it run on a battery?

No. It plugs into a wall outlet, so you need to be near a socket. That also means it never loses power as a charge drains.

Can I control the heat?

The heat function is usually on or off rather than adjustable. Treat it as a warm add-on to the kneading, not a deep heat treatment.

The wrap is a fixed U-shape. It sits best on average shoulder widths; very broad or narrow frames may find the nodes land off the tight spots.

Cordless models cost more and need charging but let you move around. This one gives constant power and simpler controls, with less flexibility.

Short sessions of about 15 minutes are typical. Skip it on injured, inflamed or numb areas, and check with a doctor if you have a medical condition.
