Because the mouse features 45° angles, you do not need to place your hand completely flat on the CHERRY MW 4500. This results in a more natural hand position, which allows you to work without fatigue and with fewer problems with your wrist and tendons. The resolution can be adjusted to one of 3 levels, with a maximum resolution of 1200 dpi, allowing precise navigation, and is easy to adapt to your preferences. Two additional thumb buttons allow you to jump to the next page or previous page in your Internet browser by touching a button. The extra small nano receiver can remain in your laptop without problems, or will find space in the bottom of the mouse. An all-rounder for the office or for home use,Part Number JW-4500.
