Just got a PS4, play a lot Destiny so got these extended thumb sticks, pretty cool, they take a while to get used to but the right one fell off off to the second game I played while fighting the boss. I ruined my entire progress by trying to get it back at the wrong time. I wish there was a way to secure it with a rubber band or use heat shrink tubing so this doesn't happen again. Pretty expensive for what they are. They just snap into place and my controller is new, I didn't expect it to fall off.
