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 its actually a more natural hand posture and thus reduces the risk of wrist problems and it doesnt matter if youre right-handed or left-handed, because the CHERRY MW 4500 is also available as the CHERRY MW 4500 LEFT. Its 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. The CHERRY MW 4500 mouse is not just good for your posture. It also feels nice, is comfortable to hold, and is fun to use, whether in the office or at home. To adjust the speed, the resolution can be set with a button in 3 levels up to 1200 dpi. The extra-small nano-receiver can be easily kept in the laptop or the bottom of the mouse.
