Input:
The mouse works ok  if you want a trackball - where you don't move the mouse to move the cursor, but move the thumb ball to navigate the screen.  I was specifically in the market for an optical mouse - one that does not use a rollerball on a mouse pad, but uses reflected light under the mouse to navigate.  Calling this an optical mouse is misleading - make sure a track-ball is what you want when you buy this.

Options:
A: very positive
B: positive
C: neutral
D: negative
E: very negative
Answer: C: neutral
