The ROG Harpe Ace Mini is the cousin of the carbon fiber ROG Harpe Ace Extreme, only far less extra. It's just 2 grams heavier than the 47 gram Ace Extreme, though rather than carbon fiber it uses its minimal size to stay light and easily flingable.
Marketed toward pro FPS players, and anyone who needs absolute pinpoint accuracy in the games they play, the Harp Ace Mini uses the same immense 42,000 DPI ROG AimPoint Pro sensor, to prove without any question that your mouse isn't the thing making you miss all those headshots.
In hand, the Harpe Ace Mini feels almost nonexistent compared to the more MMO focussed mice I'm used to. Next to the Razer Naga Pro this thing feels like it's filled with helium.
That's partially thanks to the miniscule size, but also the lack of buttons. Where an MMO mouse might have buttons in the double digits, the Harpe Ace Mini packs just seven.
That's your standard two left and right clickers, a clickable scroll wheel, plus two buttons on the right side, and two on the underside.
