The Willow

A new device seems to have hit the market place with massive advertising.  Called the Willow Curve, it seems to be little more than a heating pad with lights - little red ones.  At first I  thought it may have a Transcutaneous electrical nerve stimulation (TENS) component, but I could find no evidence.  This could have a positive impact on pain.  But no, there is nothing I can see other than heat. Nothing in the ads is suggested other than heat - not even a vibratory component.    A typical heating pad costs about $20.  This new device has a price tag in the hundreds of bucks.
