• Pros Inexpensive. Built-in touchpad and mouse buttons. Excellent wireless range. Supports Windows 8 gestures. • Cons Small, somewhat cramped keyboard. Small touchpad.

Keys are not backlit. • Bottom Line The Logitech Wireless Touch Keyboard K400r is a good choice if you want to control a home-theater or living-room PC from your sofa The Logitech Wireless Touch Keyboard K400r ($39.99) is designed for folks who want to control a living-room PC that's connected to a large-screen display or TV, while kicking back on a sofa or sitting across the room. The is a good choice if you want to stream music, as many of the function buttons are programmed for that purpose. Not only is the K400r wireless, it also incorporates a touchpad with mouse buttons so you don't have to futz with a physical mouse on any convenient surface. The keys have chiclet-style caps, although the K400r's keys are close together, with no frame to separate them, unlike in a typical chiclet-style keyboard. The keyboard is relatively cramped, though not oppressively so.

Its letter and number keys are a bit closer together than wireless keyboards, such as the, and the. Some of the keys, most notably Enter, Backspace, Shift, and Backslash, are narrower than on the other keyboards. To the right of the keyboard is the touchpad, which, at 3 by 1.8 inches (WD), is smaller than the touchpads on most consumer laptops.

It's large enough to be useful, though there were times, when performing one gesture or another, that I found myself wishing for a bit more swiping space. Below the pad are the left and right mouse buttons; the left button, which generally gets the most use, is slightly longer than the right one. Wireless Connectivity This keyboard includes a wireless receiver that plugs into a computer's USB port and allows a direct connection with the K400r, as well as other compatible devices.

The dongle can be stashed in the keyboard's battery compartment, located underneath the keyboard, when not in use, and the K400r comes with two pre-installed AA batteries. The battery compartment also acts as a riser, tilting the keyboard slightly forward when it's on a flat surface. There's an on/off switch, though it lacks an indicator light to let you know when it's on. The keys are not backlit, so they could be hard to read in a darkened room.

Also included is a wireless extender, which probably won't be necessary, unless you're far, far away from the computer and using a really big screen. In my testing, just using just the standard dongle, the range was more than 60 feet, about double the 33-foot range claimed by Logitech. The K400r uses Logitech's Unifying wireless technology, which operates on the 2.4 GHz band, and can support up to six compatible Logitech devices (primarily mice, keyboards, and touchpads). Like most wireless keyboards, the Unifying dongle occupies a USB port.
