This is the flexible head massage wand that allows you to apply heated air directly onto the area being massaged. It has a quiet heating fan that provides a contact temperature of 115-130º F in less than 15 seconds. The heating fan motor is vibration-damped to focus energy to the vibration head, which oscillates at 6,500 vibrations per minute with a gentle percussion stroke force of 1/4", resulting in soothing vibration that can be applied to tired muscles or sore joints. The flexible head is made of soft EVA foam, and the wand may be used to massage with or without heat. Plugs into AC with 10' cord. 12" L x 3" W. (1 1/2 lbs.)
