Best Trackballs, Xah Pick
Here is the best trackballs, judged from my own experience and reading tons of reviews. When it comes to trackballs, people have different opinion on which is best.
Nulea M505
Nulea M505 Trackball- Cheap, Excellent quality.
- I don't like buttons placed the side, because it forces you to grab the thing and put hand in pronation. Remedy is to swap left and right buttons in operating system.
Slimblade
Slimblade Trackball- Most ergonomic.
- No physical scroll wheel.
- Twist ball to scroll (you can just swipe finger on the rim). This is also a bad point, because you cannot scroll and move cursor at the same time, sometimes required in some 3D apps.
L-Trac
L-Trac- Highest quality built.
- Real bearings. Roller bearing.
- Expensive.
- Wired.
- The scroll wheel need some reach.
- Only 3 buttons sans buying extension.
Kensington Orbit Trackball with Scroll Ring
Kensington Orbit + RingFor a basic, 2 buttons, trackball, this one is best.
This one is well-loved. Medium sized ball, only 2 buttons, low price, and its scroll ring is best among ALL trackballs.
Logitech M575
Logitech M575 TrackballThumb based ball gets you thumb problem. But for occasional use while traveling, this is good. Also, the Scroll wheel makes annoying scratchy noise.
