Strap yourself in and prepare for a wild ride of technical issues depending on your setup.
I have an X55, and when coupled with Windows 8 or 8.1, and USB 3.0 ports, there are a LOT of reports of problems with both the stick and the throttle ghosting. If you can fix the problems, it's a nice stick with plenty of switches and buttons, but it took hours of tinkering on the phone with Saitek tech support and searching various different forums.
