Our Verdict

Razer Viper Ultimate

Logitech G303 Shroud Edition

The Razer Viper Ultimate and the Logitech G303 Shroud Edition are ambidextrous-shaped wireless gaming mice with exceptionally low click latency and consistent sensors. The Razer has a pair of buttons on both sides, making it suitable for both left- and right-handed people, and it has customizable RGB lighting. If you have small hands and use a palm grip, you'll be more comfortable with the Razer since the Logitech's diamond shape isn't suitable for this grip type at all. If you don't like lighting, the Logitech is a better choice. It has a diamond-like shape with large, smooth-gliding mouse feet.
