Shape

No changes have been made to the shape of the Harpe Ace Extreme compared to the Harpe Ace Aim Lab Edition. The front and rear barely flare out, the sides don't curve inwards much, and the hump is centered, sloping down gradually to both ends. Much like on the regular Harpe Ace, the scroll wheel sits lower and farther towards the back, which has the area around the scroll wheel raised. This effect is further compounded by the main buttons featuring comfort grooves. Furthermore, the Harpe Ace Extreme has small ledges framing the main buttons, where one's fingers can be rested, though they are not as wide compare to the ones found on the Razer Viper V3 Pro. Compared to the regular Harpe Ace, the side buttons being much smaller is notable, which is due to the fact that they cannot be part of the carbon fiber top shell.


As for grip styles, I'd say the Harpe Ace Extreme is mainly suited for claw and fingertip grip, with palm grip at least being possible. It is a medium-sized mouse with a barely pronounced hump, which should make it suit medium to large hands. For reference, my hands are 19 cm long and 10 cm wide, and I found the Harpe Ace Extreme comfortable in claw grip.
