Logitech Ergo M575S Wireless Trackball Mouse
Trackballs work for some -- but they require relearning everything and most users quit within a week.
- Trackball design eliminates wrist movement entirely -- but requires 2-4 weeks to relearn
- 4.3 stars -- lowest rating of the mice in this review
- Steep learning curve means most buyers revert to standard mice within a month
Best For / Not For
Best for
- Committed trackball converts who have used the format before and prefer it
- Users with severe wrist injury where any wrist movement must be eliminated
Not for
- Most buyers seeking wrist pain relief -- a vertical mouse solves the problem with no learning curve
- Anyone who does precision work like photo editing or design -- trackball accuracy is lower than a standard mouse
Key Details
Why Trackballs Are Not for Most People
Trackballs genuinely help some users -- specifically people who have used them for years and built the muscle memory, or users with severe wrist conditions where eliminating wrist movement is a medical necessity. For everyone else, the steep learning curve creates a worse situation before it gets better. Most buyers who try a trackball for wrist pain experience a period of frustration and lower productivity during the adjustment phase, then revert to their old mouse. The Anker vertical mouse solves the same underlying problem -- reducing wrist strain from pronation -- without any learning curve. Try a vertical mouse first. If it doesn't solve the problem, then consider a trackball.
Pros and Cons
Pros
- Eliminates wrist movement entirely -- maximum wrist rest
- Logitech quality and Bluetooth connectivity
- Works well in tight desk spaces where a mouse cannot move
Cons
- Steep 2-4 week learning curve for most users
- Most buyers abandon trackballs and return to standard mice
- Lower precision than a direct mouse for detail work
- Thumb fatigue from ball control replaces wrist fatigue -- not always an improvement
Bottom Line
Skip the Logitech M575S unless you have used trackballs before or a doctor has specifically recommended eliminating all wrist movement. Buy the Anker vertical mouse instead -- it solves the same ergonomic problem with no learning curve and 53,000 reviews of proof.
