Logitech K400 Review
Computers began to invade the living room, allowing cable cutters and dead PC gamers to enjoy content on the big screen. Software support for sofa computing has been superior, with many media and gaming services now offering control via remote or gamepad. But the keyboard remains stubborn. Giant and large wireless keyboards, often even useless away from the table.
Logitech K400 offers a solution. Small, wireless, and features a built-in touchpad, this set of buttons seems ready to handle any situation. It’s big enough to be used for average productivity, but also small enough to be used on a sofa with a home theater or gaming computer. Better yet, you can take this keyboard for $ 40 or less. Does all this add great peripherals, or does a low price means cheap construction?
Well designed, built at a low price.
The keyboard is usually not known because it is too engineered. And why should it be so? Most spend their entire lives looking to a table and moving no more than a few inches to the left or right. Cheap plastic is standard, and most users don’t notice it.
The blacktop panel and the white bottom panel appear to be blocked together by prayer, and the keyboard body creaks and groans when handled harshly.
Although building quality can be better, the design shows more thought. The four grippy rubber feet keep the keyboard in place as long as it used on a flat surface. But they are also relatively flat and round, which ensures they do not prevent sofa use. The keyboard also benefits from the small, lightweight, and slim nature that makes it easy to take and use in front of the television.
There is no business, only pleasure.
Typists and productivity nerds will not be happy with the feel of the K400. The keys are backed by a rubber dome (familiar on inexpensive keyboards), which results in a springy and unclear experience. The concise layout exacerbates the problem by miniaturizing many buttons and providing less space between them.
Only K400 from Logitech can handle the sweet spot: big enough to use, but small enough to store.
But let’s be real. This keyboard is not made to offer an exceptional typing experience. Flexibility is the goal, and the score is better from that perspective. All the small keys are in the right position and require a little effort to activate it, making it easy to use when relaxing. Logitech also cleverly elevates the top line of function keys, which provides a frame of reference for users and makes it more accessible.
That’s important because the function keys, for example, can stop, play, or adjust the volume.

Unusual touch
Touch-keyboards have never been heard before, but are far from ordinary, and the K400 is the only Logitech keyboard that offers them. The surface is available for small touches and has no texture, which in turn makes navigation a bit of a task if the cursor sensitivity left at the default setting. Bringing up sensitivity in Windows largely solved our problem.
Two large mouse buttons sit under the touchpad. Its size makes it easy to find and activate, which is useful when using a device in a dark home theater. We also found that multi-touch scrolling works well even in fussy software like games. However, due to the size of the touchpad, pinch-to-zoom is rather complicated.
Conclusion
From material to build quality, the K400 will always remind you that it only costs $ 40 (or less, if you shop online). It’s a tool, and not a very well made one at the time.
We judge each tool by how well it does its job, and, by that measure, we can find some complaints. We like the backlight and the larger touchpad, but at the same time, appreciate the lightweight of the keyboard. It’s a versatile device that can replace almost every input that you usually use with a home theater PC remote.
The Bad
- Cheap plastic construction
- Touchpad feels small
The Good
- Perfect size for couch use
- Lightweight
- Inexpensive
Conclusion
The perfect size for the couch, it isn’t flawless, but you’ll be hard pressed to find a keyboard as good for the price.
