Logitech K120 Wired Keyboard and B100 Mouse Combo

The Logitech K120 keyboard and B100 mouse connect through two USB ports and arrive as a single package. The keyboard uses a standard layout with a thin profile measuring .93 inches in height. The optical mouse provides 1000 dpi tracking and three buttons with a scroll wheel. Both devices are finished in black and work with either hand.

Refurbished USB Wired Peripherals Ready for Daily

The set is sold in refurbished condition and draws power directly from the host computer. Each device terminates in a standard USB Type-A plug, so no batteries, charging cables or wireless receivers are required. The 17.72 inch keyboard width fits most desk spaces, while the 6.10 inch depth keeps the footprint compact. The symmetrical mouse shape suits left or right handed operation.

Practical Limits of a Basic Wired Input Set

The 1000 dpi sensor covers everyday office navigation but may feel coarse for high precision creative work or fast gaming. Three buttons and a single scroll wheel omit side controls or programmable inputs found on advanced models. The fixed USB cables restrict placement to the length of the leads and occupy two ports permanently. Buyers who need adjustable sensitivity, wireless freedom or extra macro keys should look elsewhere.

Questions about this item

What does the USB wired interface cap in practice?

USB wired provides a direct connection for the keyboard and mouse without latency or battery charging, limited only by the host USB port.

What physical space do the keyboard dimensions require?

The keyboard measures 17.72 inches wide, 6.10 inches deep and 0.93 inches high, so allow that footprint on the desk.

How are both devices installed and what step is often missed?

Plug the keyboard USB and mouse USB connectors into two free USB ports; the step often missed is ensuring both ports are fully seated for detection.
