Finally, a really unique feature on the Saitek PX2500 is something they call ?Analog Direction Lock.? This feature allows you to set each analog stick to be either free in both the X-axis and the Y-axis, limit it to Up/Down motion, or limit it to Right/Left motion. My original thought was, ?Oh, yeah. Like I?d ever use THAT feature!? After playing with it a little bit, I loved it. If you play racing games, you can lock the left analog stick to provide accurate analog output for ONLY Left and Right. This is especially useful in games that have a function assigned to Left/Right which is not related to the action assigned to Up/Down. ?Lock out? the one you rarely use and you won?t accidentally do the wrong thing. The locking mechanism is a simple ring around the base of the analog stick, and can be switched from one mode to another with little effort, in relatively little time. Will it spontaneously pop from one mode to the next while you?re playing? No, there is a small button which must be depressed to rotate the dial and change the modes. All this, combined with a nice, fairly average weight, excellent balance, and a design that looks like Quake meets Duke Nukem (complete with the ?Radiation Hazard? symbol on the analog sticks in yellow), makes for an excellent all-around controller. An excellent choice for the gadget lovin? gamers out there. Get your hands on some unique features. No Slow or Turbo Fire here.
