Generally, the mouse makes a fairly valued and solid impression.
When it was all accessories if any, which you could wish for - especially the weights are a great way to customize the mouse to your own preferences.
The mouse has a total of 8 keys (11 keys is misleading), of which really can be 6 use meaningful: the two mouse buttons for index and middle fingers, operated with the thumb back and forth buttons. and a button that is below the thumb rest and is quite difficult to reach. Another key is obviously intended for the ring finger - on the right side in front - but it is in the normal hand position just outside of the ring finger and is therefore completely useless.
The mouse wheel, and a reset button under it, which regulates the DPI used work wonderfully.
Praise for the DPI control, dadruch you can quickly and easily adjust the cursor speed when required.
What I love about the mouse also good like this is that you get the built-in technology here at a low price. Despite some criticisms detract from the joy:
-The "Ergonomic design" is pretty screwed up: The mouse is unnecessarily large, unusable for left-handed, two keys are placed uncomfortable. It also interferes with prolonged use, the ring finger is not the right place to be.
-The Control in games, even after the settling and adjusting the most comfortable Gewi Chsts / DPI still hakelig and unintuitive. This may be simply a matter of taste.
-The Green light that the current DPI display lights intrusive light, which can be seen in the notebook screen, for example - or otherwise interferes with the game atmosphere.
I'm quite happy with the mouse, however, you should think twice before buying, if you can do with the strange shape of the mouse slightly.
