A bit pricey but works as intended. My original dpi is 800 and using this mouse pad is great as it doesn't matter how much your mouse weighs when using it. It can lighten a heavy mouse and improve micro-adjustment and rotating speed. I'm not going to talk about the downsides that are truly inherent in all hard pillows. Only the price is a bit high. I would recommend aiming with your wrist, otherwise you can slip and sway more. I would also recommend an ergonomic mouse that you can control.
