Logitech M570 Wireless Trackball
This is came out in .
This is a improvement over Logitech's previous Logitech Trackman Wheel.
- A scroll wheel! Excellent.
- 2 extra programable buttons. (used for example for next/previous page history for browser) This is extremely convenient.
- Laser tracking tech. (No need to clean the ball anymore.)
- Thumbnail sized USB receiver.
Overall, it got positive reviews. However, compared to the classic Logitech Trackman Wheel (red ball) , the ball is a bit smaller and is a little more stiff to spin. This is also twice as expensive.
