It does EXACTLY what it says it does. If it dosnt do what it should for you, than either theres a glitch (there hasnt been one for me) or YOU are doing something wrong. It does take a very little time to understand/get used to the positioning, but its pretty simple after that. Definatly a must buy, especially if you have a 3d app that you can move from left to right or rotate.
