The ASUS mouse is characterized by its good workmanship, ergonomic shape, precision and low volume. It can be used on many surfaces (mousepad, wood, glass, fabric and stone) and its wide range of functions makes working easier. Nevertheless, due to their special shape, it takes practice to handle it.

Precise, versatile and quiet mouse, only with a couple of limitations.


The mouse is only suitable for right-handers due to its special ergonomic shape. Because of its plug & play function, it can be used immediately after it has been connected. It can be used on all tested surfaces (mouse pad, wood, stone and fabric).

The mouse from the CSL is quiet in its application. With an average measured keystroke of 46.3 dB, this mouse is the second quietest in our test. The volume of the individual keys was 57.2 dB and that of the mouse wheel 34.5 dB.

Scope of functions

With its six different function keys, this wired mouse has a comparatively large range of functions. With its browser quick function keys and scroll wheel it is possible to surf fast and uncomplicated. In addition, the CSL Vertical Ergonomic Mouse has a DPI switch button that can be used to change the cursor sensitivity in two steps. In addition, the CSL has illumination on the left side of the mouse.

In order to test how precisely the mouse can be used, I tried to draw the lines as accurately as possible. This mouse is very precise. Due to its special shape it can take a little practice for some users to get used to the precise operation of the mouse.


The CSL Vertical is specially designed to fit the requirements of a healthy way of working and is very comfortable to hold. The surface coating of the mouse makes working even more comfortable. However, there is also a small weakness of the mouse here: grease stains adhere easily. It should also be noted that the shape can take time to get used to for users who are working with a mouse of this type for the first time.

We have evaluated almost 1400 reviews on the Internet. In summary, it can be said that about 85 percent of buyers are satisfied (4 stars) or even very satisfied (5 stars). Partially (2 stars) or completely dissatisfied are about 10 percent of the users. The average score at the time of the evaluation was 4.3 out of 5 stars.

How do you like this product?


Can anyone tell me if the scroll wheel has a tilt function, for example to scroll sideways?
Is the thumb in the curvature by itself or do I have to keep it pressed to prevent it from slipping out?
No effort is necessary, the mouse is adapted to the natural shape of the hand, which results from the lateral position of the hand when guiding this mouse.
How to use/assign the extra buttons of the mouse?
Install the mouse. Then adjust with the software.
