Once I got it adjusted and found the setting for me, it provided relief and relaxation. It took a little getting used to but I'm a big fan and highly recommend it. If you need relief from a sinus headache, this is the one for you. I don't suffer from migraines so I can't comment on this but have had them when I was younger, I wouldn't recommend this for that kind of headache. So far it has gotten rid of my headaches and kept them away. I now use it just to relax and meditate. You can decide but me, I'm so glad I found this gadget.
