What we can tell you
A large finger-operated trackball with a scroll ring and an ambidextrous body. Two things here are inferred rather than published: no source we could read prints a button count, so the filter tag rests on the fact that every variant of this design is a four-button-plus-ring layout, and the retailer rating was dropped because it came from two reviews. The manufacturer’s site refuses every request.
What the specifications favour
- A large ball with a scroll ring, usable with either hand
- Cabled, with nothing to pair or charge
- The button tag is flagged as an inference rather than presented as a figure
What to check before you buy
- No button count is published anywhere we could read
- The manufacturer’s site could not be read at all
- No sensitivity range or weight is published

What this page is based on
We have not tested this product. This page summarizes published specifications and retailer information; the sources and price dates are shown below. A missing value means it is not recorded in this comparison.
What we are not sure about (2)
Check the following details before ordering, especially where variants differ or information is incomplete.
How many buttons this has
No button count is published on any source that could be read. It is grouped with basic mice because every Expert Mouse variant is a four-button design with a scroll ring, but that is an inference rather than a published figure.
Why no rating is shown
Best Buy showed a score based on two reviews. Two is too few to mean anything, so it is not shown here.
