I bought the mouse as an entry to make in the vertical mice.
Through the many benefits of a normal mouse, I noticed recently muscle tension in his hand and wanted to prevent this.
The mouse itself is the material produces high really good, it fills up on dibasic. Had already 10 euros mice had in his hand who felt like cheap junk and also reacts so.
The keys have a good "click" feel. Only the wheel button wobbles slightly "lateral", which disturbs the overall impression.
When laser mouse you have saved, you will notice this quickly if're upgrading from a Logitech mouse.
Especially when the mouse surface is not smooth, you realize that to work the impossibility Pixeleksakt.
When working precise you realize very well the weak laser mouse.
Now to the verticality of the mouse or the main reason as a mouse to buy.
The familiarization is extremely zeitwiedrig and which has taken me 2-3 weeks.
This comes about because of the operation of a vertical mouse completely different muscle regions of the arm to be used and the hand is even completely relieved. It feels as if you had never seen a mouse, let alone a used. Anyone who has ever worked with complete computer novice will know what I mean.
In the beginning there is a before and the laser had been installed incorrectly, since the mouse pointer when push up slightly pulling to the right. By the time you use the mouse properly.
The length of the mouse with the palm rest corresponds to a Logitech MX518.
If a Chill before huge, since it is the largest mouse is really I've ever had and yet so small.
If you enclose the mouse with your hand then the fingers are about the mouse buttons.
The buttons are used with the second phalanx and not the fingertips (third phalanx).
The size of the hand of the middle finger is more on the wheel instead of on the right mouse button.
The right mouse button is still used by the middle finger, but the wheel tends to heavily use the middle finger rather than your index finger.
To get the size of the mouse more aware, I recommend Youtube videos.
The hand itself is about 30 degrees tilted to the left, allowing a fairly natural arm position.
Personally, I have very quickly felt a relief of the hand and fingers.
That came by because I no longer desperately hold the mouse and rest your fingers all the time on the keys.
Conclusion:
On the whole the mouse is quite good, when I consider that I have paid the mouse for 22 Euro with delivery, it is OK:
The weak laser mouse of a bad sampling has ruined the product almost completely.
Perhaps this problem exists only with the radio version and offer corded here is better.
