But now we come to what you should consider in advance / know.
I bought the mouse, because I currently Elder Scrolls Online (TESO) games. Since I found the "very funny" because I stand on devices that are a bit unusual.
First, the driver should be set. This is very simple and logical of Equip. The color of the button illumination can be continuously adjusted. The mouse wheel is fixed lighted in accordance with the DPI. The DPI number can also be preset continuously.
Now time to practice. On the side buttons have to get used to all cases first. After a while, the operator goes quite well out of hand.
However, I find the mouse for my 'normal' hands almost too small. When I put my hand on the mouse (normal), the thumb is already using the keypad out, so that is the top row quasi touched by the middle of the thumb. That's OK, for the second row must be the thumb, however, already buckling. And for the bottom two rows must thumbs already tense arg or the entire hand "Around", which then leads to a slating mouse.
Therefore, you can place there the "less important elements". In TESO is OK, because you can use only 5 skills anyway. But who has a 10 or even 20 bar, may well continue to have the better cards with the keyboard.
Also, I have always problems with it at the same time the mouse button (action) and to press the action key. But that can not be matter of habit.
As one with the thumb on the side of the mouse "pushes" verreißt you the mouse is actually principle. Not change the ridiculous weights nothing.
In addition, the keys are actually much too small. At least for my taste. But can not say whether the greater in Razor or Logitech now.
So one comes already clear, but I would not have minded if they were slightly larger (in which case the handling of the rear / bottom) series probably would be even worse).
So the whole is certainly a matter of getting used to, but you should all be pre-let it go through your mind once before but then afterwards another device, which is unused in the corner.
It is gratifying that we can assign the keys arbitrarily. So you can then also use applications, which I personally very important is to select, for example, functions.
The selector switch for the profile is "hidden" on the bottom of the mouse. Since there is no indication of which profile you because just selected, you should do so via the button illumination by each profile you are a different color. The profiles are thereby saved directly to the mouse, so you could use it without a great driver installation on other computers (which I find very important, because I no longer leave the house without their own mouse * wink *).
So technically and level of equipment, the mouse is very valuable and definitely worth buying.
Whether you order is necessarily faster than a normal keyboard, everyone should decide for themselves.
