Visually and ergonomically very successful.
The extras such as variable weight, quick change of sample rate and Teflon "feet" make a positive to handle noticeable.
In addition to the (programmable) keys (including forward / backward), but I find the snapping of the mouse wheel awesome!
In addition to the previously known mode of "line by line" -scrollens, can also exhibit the snap and the wheel spins freely (even poke and it still revolves around 7 sec on). In long text documents / websites I can hardly imagine navigating without this feature yet.
In particular, "Ingame" plays the G500 from their strengths and has not yet let me down.
