Stay at the top of your game with the Glorious Model I. First off, it's ultra light - with the honeycomb shell it's down to 69 g. It's precise too - the Glorious BAMF sensor is designed to compete in esports, so you know that if you miss, it's your skill to blame. All 9 buttons are fully programmable, and you can even swap the thumb buttons to get the ideal combo for you. Great for MMOs. Finally, it's built to last. The Glorious switches not only produce crisp and consistent clicks, they are expected to last 80 million clicks - that's many years of intensive gaming.Good to know- Supported by the flexible Ascended Cord and G-skates, it glides over the mat like there's no friction at all- Millions of colours and LEDs all around - this mouse takes RGB lighting seriously- There's a DPI switch to adjust on-the-fly, and the DPI indicator lets you know which value you've selected
