1. Many ignable ons, with the ability to configure different configurations for different applications. For me, it's ok. a big plus, because working in CAD (solid, altium), or surfing the internet, or playing cyberpunk (lol), I use one mouse.
2. Wireless, laser. Once again: wireless, laser. Turn on the movie and climb onto the sofa with the mouse so that you can turn up the volume, or start the next video. You can't with a wire, but with this one you can. IR will not work properly on sofa surface (tested), G604 works.
3. Good weight. I like heavy mice, and this one has a good weight if it costs a battery, and an excellent weight if it costs an alkaline battery.
4. Fast scrolling. I previously encountered this topic and I did not like it, but I changed my mind. It is very convenient to scroll through the specs and datasheets. When I got used to quickly switching between scrolling modes, the thing generally became indispensable.
5. Lack of lighting. I think it's not a secret for anyone that the RGB theme is slowly returning to brothels and casinos, where it came from, and is becoming a bad manners in modding. I am very glad that aesthetics are back in value. The G604 has one small indicator, which is enough.
6. Built-in memory in the mouse. It was an indescribable joy when I realized that the configured Ctrl + C and Ctrl + V work not only on the desktop, but also on the laptop (without any G Hub).
