This was selling for $57.99 yesterday and is now the lowest price ever from Amazon.
I have been using the mouse for the past couple years and find the form to be extremely comfortable. When you customize the quick buttons on the side it makes your most common commands (such as copy/paste) much faster and easier. This mouse can last up to 40 days on one charge and only needs 4 minutes of charging time to have enough power for a full day of usage!

- Easy switching between computers with the touch of the button
- Tracks virtually anywhere – even on glass: the dark field sensor tracks flawlessly even on glass and high-gloss surfaces (4mm minimum thickness)
- Advanced power management: up to 40 days of power on single charge. You can get enough power for a full day of usage in only 4 minutes, with No downtime while recharging
