Actually I don't even know what else to say. I bought this mouse to replace the original HyperX Pulsefire, which worked properly, but lost its aesthetic appearance (began to peel off). The wheel creaked almost immediately, but I did not consider this a significant drawback. Very in vain, less than 8 months of use and there was a "scroll" - you turn the wheel down, and the screen jumps up and down. I didn't even know it was under warranty. Unfortunately, there are no purchase documents left. In general, with HyperX mice, I'm done. It doesn't matter how cool the mouse's sensor is if it breaks like a noname for half its price.
