When asked told me the seller immediately by email that the USB flash drive into the mouse connector itself (namely pull on the bottom side handball, and whoosh off the USB stick is out). The seller has also attached a picture where you can see the supergut. Well, How to describe the picture ... I was missing in the package.
The mouse does not only look really great, but it is super good and comfortable in the hand; the mouse wheel is finally right and practicable to do so tiny as in normal mice. Overall, well thought-out ergonomics, I think.
The (blue) lighting can be adjusted. I think it's awesome when the mouse is clearly visible at night. 3 settings:
Blue on
Blue off (in the off-position shows the mouse but that it is still in operation)
Operating off
Total:
For me, an absolutely super good value for money and I'm very glad that I gave a (hitherto unknown) seller a chance. The mouse is awesome and I can only recommend. Previously unknown producers are not necessarily worse than the big names here so go elsewhere (and where you may be more than the technical product pays the name itself).

After gambled neighbor I can tell that this mouse has ingame proven genuine. Reacts fix, the hand is not hard, easygoing. As I said, great part!
