The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Logitech Ergo M575S is the default entry point for thumb-operated trackballs. PCMag calls it a well-built, more ergonomic alternative to a traditional mouse that is 'held back only by a design that won't quite fit everyone's' hand, which captures the recurring theme in community discussion. In r/Trackballs, owners praise the blue ball as one of the smoothest they have tried, while r/gis users credit thumb trackballs with making desk-bound work more efficient.
What reviewers liked
- PCMag rates it well-built and genuinely more ergonomic than a standard mouse
- r/Trackballs praises the ball as one of the smoothest available
- Quiet clicks plus Bluetooth and encrypted USB dongle connectivity

Where it falls short
- r/Trackballs users with large hands find the lower profile less comfortable
- One community thread reports grippier ball movement with more stiction
- A YouTube reviewer flags the forward/back buttons as an awkward reach
- No high-trust independent lab measurement in the supplied signals

Across the reviewers we read, the Logitech Ergo M575S is the default entry point for thumb-operated trackballs. PCMag calls it a well-built, more ergonomic alternative to a traditional mouse that is 'held back only by a design that won't quite fit everyone's' hand, which captures the recurring theme in community discussion. In r/Trackballs, owners praise the blue ball as one of the smoothest they have tried, while r/gis users credit thumb trackballs with making desk-bound work more efficient.
The disagreements are worth surfacing. r/Trackballs commenters with big hands found the M575S's slightly lower profile less comfortable than the older M570 or the pricier MX Ergo, and one thread flagged the ball as grippier with more stiction than expected. A YouTube reviewer also noted the forward and back buttons are an awkward reach. These are fit-and-feel complaints rather than reliability failures.
With a 4.6 Amazon average across roughly 2,000 ratings, quiet clicks and Bluetooth-plus-dongle connectivity, the M575S reads as the safe, affordable trackball pick, provided you accept it as a thumb design and ideally try the shape first if you have large hands.

I've been writing about tech, including everything from privacy and security to consumer electronics and startups, since 2011 for a variety of publications.
I use the Logitech MX Ergo trackball, which is like a M575 with a more premium feel. I love it and I find it makes GIS work so much more efficient.
The blue m570 ball is one of the smoothest I've tried. The only ball I've found to be smoother was the red ball that came with the Adesso T30, ...
