Wow. I cannot believe people are ignorant enough to purchase stuff like this. Beyond just playing the game and learning where to aim without your reticule (which isn't hard) try this instead: Grab printer paper, tear out small circle, moisten back of paper dot, aim, stick to screen at center of reticule. It really is not difficult to use your brain. Beyond not spending 30 dollars, paper won't f' up your TV, you wont waste energy or a USB slot, and you wont have a dumb ass cord hanging from your screen.
