Improved sleeping
Put these on, and fall asleep very quickly, and sleep more deeply and longer.  Only been using for a month , but feeling the benefits already. Would recommend the product on the sleeping benefits alone.  They are not that comfortable though, a bit scratchy where there is the adjustment teeth on the plastic.  For such a great invention, seems the design could have been a bit more comfortable, since you are supposed to wear them to rest.
