"A reliable, no-frills wireless combo that prioritizes extreme battery life over performance."
The '3-year keyboard, 18-month mouse' battery life means you'll forget they even need batteries. This is achieved with low-power components and aggressive sleep modes, not magic.
This is a rational choice for setting up a basic home or office workstation where reliability and infrequent battery changes are the top priorities. It's a set-and-forget solution for general computing.
Gamers, programmers, and anyone who types for a living should look elsewhere for better switches and sensor performance. Users needing to connect to multiple devices or tablets will be frustrated by the lack of Bluetooth.
