Nobody really knows. I had one and I liked having it until I lost it. I can't say I felt like it worked, but it kept me on track with baseball. It was kind of a reminder that I should work hard and almost served as motivation.
im a catcher i wear one on my glove hand. it helps alot when you block one and it goes off the bottom of your palm. they def help. ive noticed a difference between not wearin one and not a couple hours after a game
I think it's one of those mental things. It works if you think it works. But hey, whatever works to keep you in performance shape. Who cares? I think they're helpful.
