The wireless version requires a new AA battery every couple of days. When the battery starts running low, instead of the inputs sticking at the last spot they were at, they all immediately jump to 0,0,0. This means that you will suddenly stop maneuvering and possibly get the "Don't move your controls so rapidly" message.
A wired one is a much, much, much cheaper choice (batteries) that's a solid system. I bought a new wired stick after having the wireless system for a couple months, so now I have both in my closet while I use my X52.
The Cyborg has lasted the longest of all my sticks except my poor old Sidewinder. Though much less functional than an X stick, they're more rugged and a tiny bit more accurate. A touch of silicon on a saturated Q-Tip over the moving part of the joystick makes it much less noisy, smoother and last longer.
