Very stable, it also allows up/down ladder movement in Half-Life with no mods. Speaking of which I'll post the HL patch too. For best results uninstall your old driver and try to earase any trace of it. This includes removing it from device manager too. During install if it doesn't find your Orb don't fret, just continue the install. After reboot when windows finds the new device, let windows look for the driver. When it doesn't find it, point it to C \Program Files\Spcware\Tools. it should find the inf. file. If not just try the other folders til you find the inf. file. Double check install, go to control panel\game controlers, the 360 should be listed and switch to OK. If you follow these steps and have trouble you can E-mail me.
