This is top-of-the-line model. Features:
- Wireless! with charger.
- 13 programable buttons!
- Scroll wheel can be set to notched or smooth.
- On-board memory. (5 profiles for storage of settings)
- Instant sensitivity (DPI) change.
- Penny sized USB plug.
This one is comparable to Microsoft SideWinder X8 mouse. I consider the G700 better, because: • 6 more programable buttons. • On-board memory. • Scroll wheel can be set to notched or smooth.
