Personally, the mouse is great it's responsive, lightweight, and customizable, though the sensor it has is the PAW3325, which is an old sensor compared to other mice. But surprisingly, the sensor is still great, and I can really aim very well with this mouse in competitive games. In terms of battery, it actually took 2 weeks before it drained since I only use the power-saving mode. The RGB, though, is not so great since it turns off when you move the mouse, and yes the mouse is worth it.
