I love this chair! BUT do not plug the massager into your pc!! it will short usb ports out!! use a good heavy duty external power supply for the usb powered massager! phone chargers hate this thing! I used it with one of my older usb charger power ports and it made the thing start to buzz and ring at 1.7=1.8 kh drove me nuts until i unplugged the chair and the power supply!!
LOVE but Warning!
