Reviewers Didn't Like

  • No side buttons, Low sensitivity
  • Pivot raises height of mouse, making it awkward to transport
  • Low DPI sensitivity, Only 2 buttons, really needs a forward & back button, While the learning curve is short, you only get out what you put into this mouse (can be improperly used negating ergonomic abilities), Short warranty
