space limitations. No installation is required: to use it, simply

slides and images even from a distance. KEYS In addition to the two
classic buttons for clicking and the wheel for scrolling pages, you'll
find a DPI button to adjust the cursor movement speed. This button,
located behind the wheel, allows you to choose between 3 sensitivity
levels. This allows you to adapt the speed to your work pace or daily
use. Furthermore, when you want to turn off the mouse, simply press
the on/off button located on the back. COMPACT AND COMFORTABLE Its
ergonomic shape ensures comfortable use. Its compact size allows you
to easily store it in a laptop bag. The USB receiver can be inserted
directly into the mouse when not in use.
