Closer ExaminationThe Habu is basically a Microsoft IntelliMouse 3.0 with Razer hardware inside, only a few changes have been made to the original Microsoft design.
One of the things that amazed me about the Habu is the way you can change the side buttons depending on how you hold the mouse, this new feature is really neat because it allows the user to trim the mouse to their exact needs. It seems well constructed and durable, to release the side buttons all you have to do is press a button on the bottom of the mouse, and the side panel "pops" out.
As you can see from the picture above, the two side panels have completely different layouts button-wise. The panel at the top of the image is for users who rest their entire palm on the mouse, the other is for players who only use their fingertips to move the mouse. The fact that you can customize the side-buttons is really nice and increases the comfort while using the mouse.
The Habu's design is aimed at low to medium sensitivity gamers because of the size of the mouse. A major design error in my opinion is the way they have carelessly abandoned the original main-button placement/design of the Microsoft IntelliMouse Explorer 3.0. The Razer style main-buttons that the Habu has are way too big and they extend to roughly the middle of the mouse, making it likely that you press a button with your palm while playing.
One of the things that is really odd with the Habu is the positioning of the optical-sensor.
It is really strange that the sensor has been placed at the bottom of the mouse back, it makes the mouse less responsive to ordinary wrist movement. This compromises the performance of the mouse because it doesn't feel balanced. It would have been much better if the sensor was located in the center of the mouse, just like on the Copperhead and the Microsoft IntelliMouse Explorer 3.0.
