"Razer aims towards productivity but also light gaming with the Pro Click V2 Vertical Edition mouse. The product aims towards a natural handshake grip at about 71.7 degrees, so you won’t feel strained even after longer work and gaming sessions. The battery can last up to 6 months in Bluetooth mode, and you also have wireless HyperSpeed at your disposal via the included dongle and the mouse can be used in wired mode while charging."
