Fremont, Calif. - Logitech said it released two mice today that can track
"virtually anywhere."

The Performance MX can track on glass that is at least 4mm thick.

Performance mouse MX and Anywhere mouse MX both feature the company's Darkfield
Laser Tracking technology, which is said to use dark field microscopy to detect
microscopic particles and micro-scratches on surfaces, rather than tracking the
surface itself. This means the mice can operate on glass - a notoriously
difficult mousing surface - as long as the glass is at least 4mm thick.

products are likely to be seen as an alternative to Microsoft Hardware's mice with
BlueTrack technology
, which offers similar claims of being able to track on
nearly any type of surface.  

Logitech mice also feature a hyper-scroll option and Logitech's Unifying
receiver, announced
earlier this month

full-sized Performance MX ($99.99) comes with a micro-USB charging system, four
customizable thumb buttons and side-to-side scrolling, which Logitech said is
the first time to appear in any of its mice.

compact Anywhere MX ($79.99) is designed as a travel mouse and comes with a carrying

Both are
expected to be available this month.
