Packaging & Installation: The mouse itself is in a little "plastic box" to the end customer. This cushions the mouse properly and locks it away. Even the really small receiver has a holder inside the box and not flying back and forth. Commissioning: mouse plugged, was recognized under Win 8.1 immediately and could be used - class! Always nice when the driver-K (r) ampf be saved.

Design & Processing: Optical already makes the mouse of course something ago, mainly thanks to the rather chic blue lighting effect they really presentable. The lighting is of course at the expense of battery life, but can be deactivated with a beautiful switch at the bottom. The mouse itself is - as you might expect -from plastic, but really well made, since nothing rattles should not rattle and there are no protruding edges, plastic appendages or similar .. The mouse fits comfortably in the hand, but that in the next point more.
Short info: Yes, after unpacking the mouse smells something chemically ... this fragrance fades, however, quite quickly. But does not bother me as enormous as some other reviewers here, I had worse.

Use and exploitation: The mouse itself offers in addition to the obligatory left / right / center buttons, two function keys on the left side that can be reached without problems over the thumb. It is comfortable to hold, neither the weight nor the material feel uncomfortable or difficult. Even with longer gaming sessions you always have a secure grip, the mouse is not slippery or similar .. On the left side, the mouse still a protruding "stabilizer", which also improves balance again under the thumb. The 4 DPI levels (short info: DPI level indicates speed at which the pointer moves -> The smaller, slower) can be easily switched via a button on the top.
The following levels are available: 500 dpi (slow); 1000 DPI, 1800 DPI, 2500 DPI (quickly). After personal testing I decided for the 1800 he stage, since you both still see where the pointer floating around, as is also fast.

Conclusion: For almost 20 you get here is a pretty smart mouse that is comfortable in the hand and apart from an initial chemical odor has no negative features. Processing, weight and handling are absolutely great for me, just like the look. Definitely worth a look!
