Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Comfortable and ergonomic
With thumb and pinky on the buttons and three fingers controlling the ball, the user's wrist lays flat on the table (or on the provided attachable wrist rest).
Pro Intuitive link between ball motion and FPS camera angle
The ball is large enough for turning it to feel like physically rotating an object.
Pro Customizable
There are many settings including acceleration, polling rate, and others that can be changed from software or the built-in LCD. You can customize the 7 buttons to do whatever you like.
Pro CPI switching
You can change between 2 different DPI settings via a convenient button located below the scroll wheel.
Pro Ambidextrous
Both right-handed and left-handed people can use the mouse.
Cons
Con Not a mouse
This is a trackball, not a mouse.
Con Questionable secondary button defaults
The upper left button, which is the hardest to use, is middle click by default. The upper right, which the ring finger naturally rests near, defaults to Back. This can be particularly annoying as the Back button is easy to brush when moving hands between keyboard and mouse.
Con Bad driver software
The driver software is buggy and crashes often.
Con Somewhat poor grip
The material the mouse is made up of can be slick especially when using with sweaty hands, something that often happens with prolonged use.
