Shape

The shape of the DM7 Switch Duo is somewhat unusual. Neither the front nor back flare out much, yet the sides curve inwards significantly, to where the mouse ends up being considerably thinner at the bottom than at the top. The hump is centered and flat, yet quite pronounced, sloping down gradually towards both ends. Effectively, the DM7 Switch Duo could be likened to a taller and narrower Razer Viper, combined with sides reminiscent of the LAMZU Atlantis. The main buttons feature subtle comfort grooves. A rather irritating design element is a recessed strip going across the sides, which serves no functional purpose.


As for grip styles, I'd say the DM7 Switch Duo mostly suits palm and claw grip. It is a medium-sized mouse with a moderately pronounced hump, which should make it generally suit most hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the DM7 Switch Duo comfortable in claw grip.
