Smaller overall size makes the Model O 2 Mini a great choice for gamers with small- to medium-sized hands who find full-sized mice hard to grip comfortably. Lighter than the competition, and the lightest mainline mice we offer, allowing for swift and precise aiming without fatigue. Despite their compact size, the Model O 2 Mini mice have the same sensor, durability, and wireless performance as their larger relatives to ensure gamers are able to play at their best with a mouse that fits their hand.
