This has basically saved my grades over the years. I've been using it for a few years now (don't remember when I bought it but yes) and it definitely works. As a student, I always write my notes by hand, not to mention having a stranglehold on pens and pencils. Over time, my hands became numb or achy from overwork. Ditto for art: rework with death grip ends in pain in hands and wrists. I usually apply this on my breaks or leave it on overnight if it's that bad, but it really helps. However, I've never spoken to a doctor about using it, so you might want to check it out beforehand to see if they're helpful or not!
