Let's see how long it lasts. You can assemble a glowing mouse, keyboard, illuminated mouse pad - and control it from the SteelSeries software. It even has a "color music" mode, when all this illumination reacts to an audio signal in a computer. Of course, the "waves" are visible mainly on the clave. With its pros: Rides smoothly, heavy, comfortable in the hand. Reasonable button layout, something close to the G502 from the log. Replaceable cable, two pieces - positioned as "thin for a laptop, thick for a computer", but I like it better in a braid, of course. It seems that the connection is made with an L-shaped plug with a latch. Easy to transport by detaching. Pop backlight, display - to disperse boredom, for photos in Instagram, well, or if the streamer wants to show off. Cons below: The soft-touch coating will peel off quickly, and there are no replacement covers in the kit, just as there is no way to quickly get them. This would be a kinetic scroll from Logitech, but alas, this is their signature feature.
