Promising review: “I heard about this product from my cousin, who used it on a trip to Japan, and it was very effective. I used it on a trip to Washington, D.C. that had several stops and delays – a total of 15 hours to get to my destination. I was comfortable when I arrived and the next morning I was ready for the day a job.” —Eleanor
