If you like the Logitech Marble trackball in a wireless version, this Adesso T40 might be for you if you are OK with some shortcomings….
Pros:
+ wireless Trackball
+ plenty of buttons to program for macros. works fine without installing any software
+ standard AA batteries to swap.
+ scroll wheel is also a button, perfect for doing 3D modeling
Cons:
– ball is terrible. you will need to buy another ball with patterns
– lose connection at least 5 times a day
– loud click sound. you will need to buy a different switch to make the clicks quieter
