1Pc Magnetic Neck Massager with Comfortable Warm Pad with Belt

They heat up quite quickly and make my neck feel better but whether they have any lasting effect I don’t know

Excellent. Heats by default for 30 minutes, can be switched to 45 and 60 with the remote. It's just a pity that you have to sit/lie near the socket.

Thank you very much for the quality of the product, I am trying to warm up my neck. It warms up very well.

Great tool, heating is great. Works well.

Warms well. Soft fabric, pleasant to the touch.
