Cozy warmth and massage, no cord required

This white cordless knee massager is for anyone who loves to kick back with a little warmth after a busy day. A built-in rechargeable battery powers it, so you can use it on the couch, at your desk or on the go. Pick from three heat levels, from about 104 to 136 °F, and three vibration modes, then check your settings on the large LED display. Adjustable hook-and-loop straps wrap snugly around the knee, and the extension strap lets it fit around a shoulder or elbow too.

Why you'll love it

  • Three heat levels: Go from gentle to toasty warmth, about 104 to 136 °F.
  • Three vibration modes: Auto, low or high for a relaxing massage that feels just right.
