I found that past the help for motion sickness (which worked wonderfully), it was also really awesome with anxiety. When I was in a crowded airport and stuck on a plane with people being less than marvelous, I turned on the wristband and it gave me a pulse to focus on which helped to calm my nerves. I compare it to the rubberband around the wrist method, but much less painful! I was not only able to look at my phone while riding in a car, which is something I've never been able to do before, but several aspects of my trip were made so much better from wearing this wristband. My boyfriend also suffers from a sour stomach after eating. He has recovered from esophageal cancer, but after the surgery, his stomach doesn't work the way it is supposed to. The wristband helped him with that as well.
