This is the 2021 upgraded model of the good old heat pad. It is really nice, build of soft flannel material. It has a controller with a digital readout to choose from 9 different heat settings. It also has multiple auto-shutoff times (from 0.5 to 8 hours) and constant on too. The controller and pwer cord are removable and the unit itself is machine-washable. We are very pleased with the quality of this product.
