I've used Logitech mice since forever, but their quality has taken a nose dive, so I bought a Razor Deathadder. Because everyone markets their products towards 13 year-olds, it's called "Deathadder" and it's stuffed full of RGB LEDs. To disable the LEDs, you must install the Synapse software which is Electron trash, because nobody writes real software any more. And you have to KEEP this software installed, to keep the LEDs off. If you uninstall it, the LEDs come right back on.
So I did what anyone would do: I took a screwdriver and a sidecutter, ripped out the leds and threw them in the trash.
Such a relief really to use Linux, the hardware just works out of the box. Or in theory could also be it doesn't work at all since there won't be downloadable drivers, but in practice all my peripherals have worked great.
If you didn’t know, there are open source drivers for many Razer peripherals that let you control things like colors and macros: https://openrazer.github.io/
