The term "SteelSeries" fits not at all good here. The mouse works processed extremely cheap. It is extremely lightweight and feels like a typical cheap plastic mouse. The size of the mouse should also note. If you're not very big hands, the thumb buttons are only reach around with to achieve. Left and Right Click are unusually smoothly, which means the bottom line, ingame will advance clicked, without meaning to. The buttons left and right of the index and middle fingers are indeed a good idea, but can these be used only with acclimatization. The button to the right of the mouse is a nice idea and currently defaults to the opening of the regional map in WoW. This works very well. The sliding properties of the mouse are mediocre. Looking at the Glider below the mouse more precisely, you can see bumps - which can again connect to cheap free processing. Overall, the mouse is not recommended - erstrecht not for this price, because here, one is already in the high-end segment, for which you get from other providers quite better quality - and can also be expected. The software, which is not included but must be downloaded from SteelSeries, makes a solid impression. It can all the typical commands are placed on any button and various profiles are stored - for example, for different Charrs.Dennoch, I will send the mouse today - hours after receiving - back and would prefer to buy it back at the other party, where I order the good workmanship quality white. In points I give the mouse 2 von 5.
