Body shapeiDescribes shell symmetry, not the intended hand. Symmetrical with side buttons on one side differs from an asymmetric right-handed body. Ambidextrous means a symmetrical body with side buttons on both sides.

Symmetrical body1Maker product pagerazer.com/gaming-mice/razer-viper-v4-proRead 30 September 2026Maker FAQ: right-handed symmetrical shape. Stored enum describes body symmetry, and left-only side buttons do not make the body asymmetrical.

Symmetrical body1Maker product pagesteelseries.com/gaming-mice/sensei-rival-proRead 14 October 2026Spec table lists the shape as Symmetrical, Ambidextrous. The side buttons are on the left side only, so the schema value symmetrical is used.
