Does exactly what it says it would - great price too!
I just traveled from Honolulu to Kyoto, then Kyoto to Tokyo by train, then Tokyo to Kuala Lumpur again. This device is AWESOME. I'm short, so my feet are always hanging on regular chairs and it really messes up your hamstrings and lower back. This time I arrived at every destination with way more energy than I usually do. This is a GREAT product. And it's TOTALLY affordable. I gave one to my husband as he'll need it too. Seriously great product. Pure honest review.
