I have no problem in believing that things like this can help with the pain (a lot). But still, author says that now he is able to type in any uncomfortable position for as long as he wants, and it sounds little scary. "See? I don't feel any pain, it's great." Well, wasn't there some reason for that pain in the first place? Maybe you feel great, but still, are you sure that you aren't permanently hurting your own body? RSI isn't just a state of mind…
