Overall score includes:

Heat-up (70%): Shows how quickly the blankets reached their peak temperature on their highest heat setting. Ease of use (30%): Assessed on the user-friendliness of the controls.

Ease of use score includes:

Controller comfort (40%): Assessed on the position of the controller connection for the blanket and the likelihood of it causing discomfort during sleep.

Cleaning (5%): Assessed on how easy the blanket was to clean and dry.
