What we can tell you

A wireless vertical mouse at a moderate price, running on a receiver. The published record is thin: the manufacturer’s site refuses every request and the retailer’s specification table carried no button count, so this page has no button figure and no weight. The rating that listing showed was rejected, because the same figure came back for a different product on the same site.

What the specifications favour

  • A vertical grip without a cable
  • Modestly priced for a wireless vertical mouse

What to check before you buy

  • No button count and no weight are published
  • The retailer rating was not reliably attributed, so none is shown
  • The manufacturer’s site could not be read at all

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

    Best Buy's specification table did not carry a button count and Kensington's own site could not be read. Several resellers describe six programmable buttons, but none is a source worth quoting, so no count is shown.

  • Why no rating is shown

    Best Buy displayed the same score and review count as for a different Kensington product, so it was not reliably attached to this one. It is not shown here.
