If it were possible to configure the mouse without software, as well as your profiles were stored in memory without the need to download software, there would be no price for it. I took it as a gift to a friend, I can’t say about the reliability and durability of all the elements of the mouse. Some pros: For the amount of up to 5000, the top PixArt 3399 sensor, a nice wheel with adjustable click clarity, a decent number of additional programmable buttons, as well as raiser optical microswitches under the main buttons, an obedient and responsive paracord-like cable, assembly (surprisingly) and whistle-blowers (RGB) where without them. With its cons. Mandatory presence of software, without it the mouse is a brick in my opinion.
