Ergonomic vertical mouse for right-hand users

The Protoarc EM11 NL -B is a right-handed vertical mouse designed to keep the wrist in a neutral posture during long sessions. It connects through Bluetooth 4.0 or a 2.4 GHz USB receiver and runs on a built-in 500 mAh rechargeable battery. The shape targets office workers and creatives who experience discomfort with flat mice.

Upgrade from a standard flat mouse when wrist

Switching makes sense when a conventional mouse causes fatigue or repetitive-strain symptoms after extended use. The vertical grip reduces forearm pronation, though the manufacturer notes a one-to-two-week adjustment period before the posture feels natural. It replaces a single-device pointer by pairing with up to three hosts simultaneously.

Three DPI levels cover office

The sensor offers 1000, 1600 and 2400 DPI steps selectable via a dedicated button, providing enough granularity for document editing, web browsing and moderate design tasks. Wireless range reaches 8 m (26 ft) in clear conditions. The scroll wheel and side buttons are not silent, so strictly quiet environments may notice audible clicks.
