For device

Look, I want to buy a new mouse, because my mouse is dying, I want to take 4a tech bloody j95s, which I will use, and if I’m not going to use a fire baton, what’s the fun of this mouse, is it prohibited or not?

As far as I know, it shouldn’t be an issue. Could you tell me what the fire button does exactly? For instance, I’m using a Logitech G502 X PLUS which has 13 programmable buttons and you can create macros (combination of key/mouse button presses).
