Title: Isn't what I expected.
Review: Do not expect to use this device as you would a regular heating pad or a hot water bottle. The device doesn't provide a lot of heat, even on the hot setting. However, this item works well if you put it on ten minutes or so before you go to bed... it keeps the foot of the bed area from having that very cold feel, allowing your body's natural warmth to take a quicker effect. It is less detrimental to your health (than a conventional heating pad) if you fall asleep with the foot warmer left on, though I would not recommend doing so.
