I’ve been rocking the Kensington Orbit wired for years now and I’ve yet to find a better trackball.
Reasons:
- works for both hands
- scroll ring
- big ball
- wired
- works reliably
I use the trackball with my left hand and a mouse with my right.
It seems like such a cheaply made product, but it just works so very, very well.
I wish it had four buttons. I use the back/forward buttons enough to justify the Expert Mouse, but the scroll wheel broke down and I eventually switched to an Adesso T50, then a HUGE.
