What was promised by the manufacturer, was also respected!
Therefore, clearly I understand the displeasure, when the release is constantly moving - but that the quality is right and everything is as it should be! I prefer to wait longer, but it was no semi-finished product.
The mouse is great in the hand, is easy to carry. The buttons are all easily accessible and have a good pressure point. Settings are possible via the driver really a lot (because so few were also the same time changed * g *).
Generally, the mouse has a very high and noble. So far I had several Logitech and Razer Gaming Mice and had no comparison to what I get here. Especially the Razer mice are indeed just as expensive.
So clear recommendation from me, the mouse is worth the money :)
