Because the mouse is tilted at 45°, you do not need to place your hand completely flat on the Cherry MW 4500 LEFT Wireless Mouse. This results in a more natural hand position, which allows you to work without fatigue and with fewer problems with your wrist and tendons. This means repetitive strain injury can be avoided, or alleviated if you already have the symptoms. The click function of the right and left mouse button can be toggled at the touch of a button – without changing the system settings. The resolution can be adjusted with a button in 3 levels up to 1200 dpi for precise navigation and perfect adaptation 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 on the bottom of the mouse. An all-rounder for the office or for home use!It feels different from any other computer mouse. But only briefly. Because when you use it, you quickly notice that a vertical mouse is different, but above all comfortable, somehow more relaxed. The angle is a bit steeper than with a normal mouse, which means your wrist is at a 45 degree angle.The angled shape of the mouse much better corresponds to the natural, relaxed position of the wrist. It feels strange at first, but it’s actually a more natural hand posture and thus reduces the risk of wrist problems – and it doesn’t matter if you’re right-handed or left-handed, because the CHERRY MW 4500 is also available as the CHERRY MW 4500 LEFT. It’s the same for prolonged working in the office as it is when you spend several hours on your computer at home. And thanks to the latest wireless technology, you don't have any annoying tangled cables.Two additional thumb buttons let you move back and forth in your web browser, and with the aid of the CHERRY KEYS software you can individually assign copy and paste functions. It will change the way you work
