Bakker Elkhuizen Evoluent Vertical Mouse 4 - Vertical mouse - right-handed - optical - 6 buttons - wired - USB

By using a compact keyboard, one can place one's mouse closer to one's body, which puts less strain on one's neck and shoulders. Unnatural postures when using one's mouse form a risk factor for the occurrence of complaints in one's wrists and forearms.
Ergonomic mouse devices reduce muscle tension in comparison with standard flat mouse devices and are much more comfortable.
Which type of ergonomic mouse is the most suitable depends on the type of work, any complaints and personal preferences.

  Pointer speed controls on the side allow convenient adjustment without even releasing your grip from the mouse.

  An extra wide lip along the bottom edge prevents the last finger from rubbing the desk.
