The concept of this product is to use extra leverage created by extending the analog sticks on your PS3 or XBOX 360 gaming console to allow for better accuracy for your favorite first-person shooter. My house got ours earlier today and were pleasantly surprised! It comes in a professional looking package like you would see in any retail store, and attaching them to your controller is painlessly easy. After testing with Call of Duty 4, Killzone 2, and Resistance 2 all signs point to Kontrol Freek's claim of +40% Accuracy were starting to look a lot more realistic. Though it does take sometime to get used to, the sticks are comfortable and responsive. The "Precision engineered leverage...for improved movement" As the box puts it, basically gives you more room, allowing you to be more precise with weapon movements. The only real issue I have is that it's just slightly harder to hit those Analog Stick buttons, when you have to click down on the stick, the higher sticks make it a little more difficult to do. My roommate ended up taking off the left one, as there is really no need to be more accurate with running.
