Logitech M570 Wireless Trackball
The Logitech M570 Wireless Trackball came out in .
This is a improvement over Logitech's previous Logitech Trackman Wheel.
- A scroll wheel.
- 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.
The Scroll Wheel
The wheel has no tilt. But can function as middle button. Require hard press.
The scroll wheel is cheaply made. It feels like 1990's cheap wheel. When you roll it, you can hear and feel some kinda rubbing of plastic. Definitely does not feel good. It is not a big deal though, just know that it isn't James Bond wheel.
For example as a comparison, the scroll-wheel of
is much better, top quality. Luxury feel.
The scroll-wheel of
is also excellent. It has 2 modes. One is spin mode, which is simply frickionless, no feel to speak of. 〔►see Logitech Mouse with Spin Wheel〕 The other is notched-mode. It's very comfortable, yet very different from the feel of the G600.
The ball is pretty good. Rolling is very smooth. If you give it a big push, it can spin for up to 2 seconds.
Ball diameter is 34 mm.

1 AA battery. The spec said 18 months. Impressive. I haven't used that long to know. Will update.
Works with Linux
Yes. Plug and play. No software needed.
5 buttons. The 2 extra buttons on top left are by default browser forward and backward buttons. You can of course use X11 to change them. 〔►see Linux: How to Swap Mouse Buttons〕
Many 1 star rating on amazon all said the button don't last long. Within 6 months or 1 year, the button becomes double click, or, when you hold it trying to drag, it drops.
This particular guy, said he button fails him after just 2 months.

he is a electric engineer, so he's able to buy replacement parts and replace the button.
It's cheap, but the scratchy scroll wheel really rubs me the wrong way. And the button wearing out after a few months is not acceptable.
I think the Elecom or Sanwa is better.
