this is the most amazing idea EVER for travel. I've used it on 3 long flights and am going on 2 more. I slept for 7 1/2 hours during a 10-hour flight and 8 on a 15-hour flight. I gave one to a friend who is also amazed by it. Can't recommend it enough! I've been telling everyone I know to get one!more info. I would recommend getting the one with the chin strap. I wish they'd offer the blue one with it as I don't like the color of the black one but the chin strap definitely helps.
