I'm one of many headache and migraine sufferers on a nearly weekly basis and I used to have to pinch this pressure point with my opposite hand to get some relief, but that would leave me unproductive for awhile. With this I can still use both hands and work, type, and move around while having the constant pressure. This really makes a difference for me, I can feel the difference after only a few minutes of wearing this. I will definitely be ordering another one, and probably in the small/kids size because the normal size one leaves a gap and if I push it further on to my hand where it's flush then it's not at the correct pressure point. And if I get both sizes I'll be able to compare them. Over all I am very impressed with this product.
