Input: I am overly please with this trackball mouse and don't know how I lived without it before. If you are only gonna use it for general mouse use, this trackball is probably gonna be overkill for you and there are many other cheaper and more practical choices for you. But if you do graphic design, video/photo/music editing, or any other task that has numerous multi key combo commands that you use repetitiously, then this mouse is a must have. It is rather large and seemingly bulky when you first use it, but you soon realize it is for maintaing a fair amount of comfort during long and/or repetitive tasks. The beauty though lies in the program that comes with it allowing full adjustability of all aspects of it. You and adjust speed, sensitivity, and acceleration of the track ball and scroll ring around it. You can program each of the four buttons to tackle six commands, either from a preset, or fully custom key command string or combo. Each button does one command and the top 2 together and bottom 2 together for a total of six. You can also set your choice of &#34;hot keys&#34; on the keyboard to engage effects such as slow(or fine) scrolling and vertical/horizontal scrolling. It has increased my workflow efficiency exponentially. Complex 3 key &#34;Command+Alt+Character&#34; type commands that I use most for a task, become single button clicks saving time and aggravation due to my limited memory ability of commands when swapping from one app to another. My only wish for this mouse is that they would add the ability in the programming software to save different profiles for your most used configurations. But I don't mind to much programming the buttons myself for now and I still give this product a 5 star and recommend it to others who have similar needs of their trackball.

Must Have For Editing/Graphic Work!!!
