Ergonomics & Comfort

  • Vertical grip with an extended wrist rest keeps your wrist and forearm in a more natural straight position, which can reduce fatigue compared with a flat mouse if you work long hours.

  • Textured, non‑slip surface and full palm support encourage a relaxed hold; there is a learning curve of about 1–2 weeks before it feels fully natural for most people.

Connectivity & Battery

  • Connects to up to 3 devices at once: 2 via Bluetooth (low‑energy) and 1 via 2.4 GHz USB receiver, with a bottom button to switch between them.

  • Built‑in 500 mAh rechargeable Li‑ion battery (USB‑C charging) is designed to last weeks on a charge under normal office use, so you avoid constantly changing batteries.



DPI & Buttons

  • Offers 3 DPI levels (1000 / 1600 / 2400), which is enough for productivity work, multi‑monitor setups, and casual use.

  • Has standard left/right click, scroll wheel, DPI button, and back/forward buttons; they are not programmable, and back/forward do not work in macOS browsers.



Noise & Best Use

  • Left and right clicks are “silent” or near‑silent, making it suitable for shared spaces, late‑night work, or recording beside a mic.

  • Best suited if you:

    • Have wrist/forearm discomfort with a normal mouse.

    • Want a budget‑friendly vertical mouse with rechargeable USB‑C and 3‑device switching.

    • Use Windows primarily (with macOS support but limited side‑button functionality)
