I bought this after trying to play COD4 (First Person Shooter) for xbox 360 and getting beaten constantly. I originally played all FPS games on PC and was used to the good old keyboard and mouse setup. Aiming with the 360 controller seemed way too awkward. Well the Maxx shooter seemed to be the answer to my prayers, guess what, it's wasn't. First off, I had to buy a wired xbox controller to make it work, that's an extra $40 down the drain. Second, it only has 2 USB ports. One for the xbox controller leaving only one for your mouse/keyboard. Ended up having to get a PS2 keyboard instead. After all this the unit worked as advertised less one important thing. You can't aim to save you life. The conversion of mouse movements to xbox controller motions is complete crap. The cursor jumps all over the place, and the tracking is horrible. After trying on 3 separate occassions to get the settings just right, including using the in game sensitivity settings, using different mice, I gave up. If your thinking of buying this for the same reasons as me, don't! If you have issues aiming via xbox controller, I have some advice. Practice, Practice, Practice, I'm now just as good with the xbox controller as I ever was with a mouse. You just have to put in the time to learn. Also, there is an inexpensive xbox controller add on out there that will help with your aim. Not sure I should mention it here but the name starts with "FPS" and and ends with "Freeks". Do a search.
