Reviewers Didn't Like

  • Removing the ability to change the DPI was not smart, No advanced features to speak of, Might be too small if you have larger hands
  • Mainly a palm grip mouse, not very comfortable when held in a finger grip due to its small size, No forward/ backward buttons, While compact it is still almost as tall as the original Whirl, Same price as full sized Whirl
  • Takes a while to get accustomed to
  • Not ideal for travel use. Occasionally feels like a balancing act. No browser buttons. Plain design
  • Doesn't work on glass, No extra shortcut buttons
