"The default keyboard for a reason: cheap, reliable, and utterly forgettable."
The '36-month keyboard and 12-month mouse battery life' claim is credible, achieved using standard AA/AAA batteries and aggressive power-saving that puts the devices to sleep quickly.
This is a pragmatic choice for basic home or office desktops, secondary computers, or for setups where low cost and spill resistance are the highest priorities. It is a functional tool, not a premium experience.
Gamers, developers, and anyone who types for a living should invest in a mechanical keyboard. Users needing to connect to tablets or modern ultra-thin laptops will be better served by a Bluetooth model.
