Unlike any other
This is not a typical massager. It sends little electrical pulses into your neck. I wasn't so sure about it until I tried it while fighting a headache one day..... and it took my headache away.  I think I like it.  It's a strange sensation and I couldn't get my husband to keep it on but I like it... even more now that I know it will help my headaches.
