I purchased the X52 when my Microsoft joystick died. It took 4 downloads & fixes from the Seitek om-line forum to get it to work - and a day later it went haywire in the middle of a dogfight on Fighter Ace. I have re-installed again & still have problems- the forum has hundreds of people complaining about it as well. Went to a cheaper logitex that is easy & works well with no hassles.
