This mouse comes with a supercharged 4K dongle included in the box! 4,000Hz polling allows for smoother, more responsive gameplay and is especially useful when using higher refresh rate monitors. This is one of the lightest ergonomic esports mice out there at only 52 grams. You'll be able to move faster, have more control, and react faster. It feels super light, yet it's extremely strong without any visible holes to keep a clean look. The optical clicks are crispy with minimal debounce delay required. This means your mouse is free from double-clicking and click latency is as fast as can be. Our optical switches are rated longer than traditional mechanical switches which means a longer lifespan. You get up to a solid 80 hours of battery life with 1,000Hz polling, which is perfect for long gaming sessions over multiple days. A longer battery will help make sure you never run out of battery in the middle of that important match, but the charging is up to you!
