The HP 925 Ergonomic Vertical Mouse (6H1A5AA) is a right-handed vertical mouse that holds the hand in a more natural, upright handshake position to reduce strain during long working days. It is aimed at office and home workers who use a mouse for hours at a time and want to ease wrist and forearm discomfort, and HP states it is certified by US Ergonomics. A detachable wrist rest attaches magnetically. The mouse connects either by Bluetooth or through the supplied USB-A receiver, which stores inside the mouse, and it can pair with up to three devices and switch between them. It has six buttons (five customisable in HP Accessory Center), a scroll wheel and a 4,000 dpi multi-surface sensor. Power comes from a built-in rechargeable lithium-ion battery charged over USB-C. Works with Windows 10 and 11, macOS and ChromeOS. It is black, contains at least 65 percent post-consumer recycled plastic and weighs about 167 g. In the box: mouse, receiver, charging cable, quick start guide and warranty card.
