Due to the slow decline of the scroll system in operation for years my MX518 was the decision to order the direct successor G400, a simple. Decisive is primarily the years and pleasant haptic design unchanged since the first series. The surface appears now in plain matte gray, but the love of it and the handling absolutely does not detract> Hint: Do not irriitieren from can be seen here Product Photo showing the mouse in light tan top show! The color is matte gray.
There is only to say that they are fully adjustable by means of new software in all respects to the functions - there is really nothing you can not change. Otherwise the keys are equal MX518, no wobbling, no nagging :-)
Conclusion: Great, recommended working part, which is also after years still improved and fun!
