Keychron wireless trackball mouse T1 HE, with a ball position adjustable to fit the thumb, up for preorder at 59.99 dollars(theverge.com)

- This is a trackball mouse where you move the cursor by rolling the ball with your thumb instead of moving your wrist. Two dials on the bottom let you adjust the ball's position up, down, left and right, and you can also pull the ball forward or push it in. - The adjustment range is only a few millimeters in each direction. The original reporter thinks even such small adjustments can help with comfort during daily use. The ball diameter is 34mm. - Cursor speed (DPI) can be changed from 100 to 2,400 with a button or the Keychron Launcher software. There are 6 buttons, and the software allows remapping functions and setting macros. - The usage times stated in the original are up to 106 hours over Bluetooth on battery 600mAh, and 98 hours with the included 2.4GHz receiver. A USB-C cable connection is also supported. Colors are black, white and transparent, and shipping is expected in early December.
