I would recommend to avoid the X55. Go for the redesigned Logitech X56 instead. They've apparently fixed the issues that plagued the X55 (which I had before the X56). So far, it seems that they might have done, and there are some extra sticks on the 56 (that replace a couple of the buttons). I love the X56, I'm just hoping that Logitech are true to their promise about reliability.Would people recommend another X52, an X55 or an X56? I hear a lot about the 55/56 quality being poor.
