Elecom DEFT Pro Trackball
Elecom DEFT Pro Trackball
This came out in 2018-05, and is one of the best trackball.
- 3 models: Wired, Wireless, Bluetooth
- Rechargeable. Just connect the USB cable to charge.
- 8 buttons. 3 on top. 3 on thumb area. and counting scroll wheel tilt as 2.
- Scroll wheel can tilt.
The left click button is actually on the thumb.
High Grade Tracking, Adjustable DPI
It uses modern (2018) tracking tech. So, not like many trackballs that's using 10 years old optics that's super slow.
Ball Spins?
Some people say this trackball has the most smooth spin, while many amazon reviews says it's the worst. I guess it depends on your luck.

My Conclusion
It's good. Good reviews on amazon.
I'd rate this or the Logitech MX Ergo Trackball as best trackballs.
