Hello, i bought recently a steelseries rival 300 cs:go edition.Sometimes, if the cable of the mouse is tightly bended, the mouse will behave very strange, moving as if it has something blocking the sensor.Sometimes if i straighten the cable, it moves normally again, but sometimes i have to unplug and plug in the cable.A friend of mine said i need a mouse pad, but i don't think so.Also, i am using a laptop, asus rog g552vw and have the latest drivers installed.
