I LOVE the Wico controllers. You've definitely got a gem on the way. I've played Track and Field on mine for hours and hours and hours and it's none the worse for it. If T&F can't break 'em I don't know what can.

FYI: I personally can only use them when I can sit it down on a table. For some reason I've never found it as comfortable to hold in my hands like the VCS controllers.
