I am giving the product
I am giving the product four stars since it does seem to be helping. There's just a lot of room for improvement with this product. If you can get one on a Black Friday sale, or your FSA covers it, it may be a good tool to add to your migraine toolbox. No one approach is a cure all for the complex condition of migraine, but it always helps to have yet one more tool int the toolbox. I would rate this tool as a "keeper."
