Reviewers Liked

  • Wireless connectivity. Two programmable buttons
  • Mac-like design stands out from the crowd; optical sensor instead of scroll wheel is an interesting innovation; curved, ergonomic shape

Reviewers Didn't Like

  • Scroll sensor is hard to control reliably. Tracking speed might be too fast for some users. Side buttons involve reaching with your thumb. Clicking the scroll sensor doesn’t do anything
  • A bit big for mobile MacBook users; optical scroll sensor isnt the best for super-accurate scrolling
