If you are someone who works and/or plays hours on end on a computer, you would know the importance of a comfortable set up.
The last thing you want is a strained back or hand, which is why an ergonomic chair and comfortable mouse are so important.
With Speedlink's OBSIDIA mouse you get an ergonomic 3200 dpi USB mouse with optical sensor and 5 buttons for right-handed use.
The back arch angle of the OBSIDIA 3200 dpi mouse measures 44mm high so it nicely accommodates your palm, allowing the weight of the hand to rest entirely on the mouse.
As far as the width and length, the OBSIDIA mouse measures 87mm wide and 113mm long. The small recess on the left side of the mouse is perfect as it allows your thumb and the "ball of the thumb" to comfortable rest on the mouse.
Two of the five buttons that come with the OBSIDIA mouse are located right above the small thumb recess, and these two buttons are perfectly designed to be triggered by the thumb's interphalangeal joint (IP) joint.
The built-in optical sensor in the OBSIDIA 3200 dpi mouse can be adjusted all the way down to 800 dpi via the dpi button built behind the scroll wheel.
The dpi button allows for toggling between four sensor settings; while the rubberized scroll wheel can scroll from left to right 2 dimensionally (2D)
