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 No key illumination
The keyboard has no backlights, making it hard to use in rooms with poor illumination.
Con Not for gamers
This keyboard works great for office work or casual gaming, but it's not recommended for competitive gamers. It's not meant to deal with the same amount of wear as a mechanical keyboard.
