Logitech K400 Plus Keyboard Overview
Let's start with the usual unboxing. The box contains the touch keyboard, the Unifying receiver, 2 AA batteries and the user manual. The Logitech K400 Plus is a wireless keyboard that is distinguished by the existence of the touchpad on the right side of the keyboard. It measures 139.9mm x 354.3mm x 23.5mm (LxWxH) and weighs 380g with batteries. The touchpad on the left side of the keyboard measures 76mm x 47mm. This 3.5-inch touchpad integrated directly into the keyboard will allow you to use a single control device in remote manipulation of your computer. This will prevent you from being bothered by the presence of a separate keyboard and mouse and allow you to benefit from a compact and well-designed device. You can use the Options software for quick configuration of the touchpad keys.
The keys
The keyboard keys are also quite quiet for a calm and user-friendly office experience. The K400 Plus is ultra-thin and does not have legs to tilt it. The material used is a fairly thick and solid granulated plastic. We nevertheless note a slight impression of “cheap” in terms of the quality of the plastic. But that in no way detracts from the merits of this keyboard: functional, practical and pleasant to use.
Below the keyboard, you will have the 4 pads which allow the keyboard to adhere well to a more or less smooth support (table, desk, etc.). On the back of the keyboard, you can find the location of the 2 AA batteries. Directional arrows indicate the direction in which the cover must be slid to remove the batteries in case of replacement. At the battery location, there is a small place to store the Unifying receiver . It is actually better to store it when it is not in use, because it is very small and risks being lost quite easily. As for the colors available, the K400 Plus keyboard can be ordered in black or white.
For multimedia
This wireless keyboard was designed to make your life easier. It can thus remotely control your multimedia data passing on your television when the latter is connected to your computer. You will no longer need to go to your PC to launch your favorite clips or songs. So you can fully enjoy and control your entertainment from your sofa or bed. The range of your K400 plus device is 10 meters or 33 feet. This is twice the distance supported on some wireless keyboards such as the Bluestork.

With this keyboard, you will have at your fingertips buttons to manage the volume and directional keys allowing you to browse your media.
Other shortcut buttons for Windows or Android are also available. These keys can be used without additional configuration. On windows , you can use the F4 to F12 keys to launch and manage your music (media player or music application depending on the windows version), switch the video output from the computer to the television, etc. On Android, you can use the F1 to F3 keys to act as the 3 buttons that we usually find on Android devices: home, back and toggling between open applications.
The primary objective of connecting the computer to the television is to be able to watch your multimedia files, your favorite series, etc. You can therefore install applications such as Kodi to make your computer a real media center. All you have to do is relax on your sofa or bed during your multimedia sessions. The whole family can enjoy it.
To activate your keyboard, simply plug the Unifying receiver into a USB port and that's it. You can then directly use your K400 Plus keyboard. You can also connect up to 6 Logitech devices to the same Unifying receiver. This is very convenient if you have other wireless Logitech devices.

If you are more of a fan of a wired gaming mouse, you can opt for the Logitech G502 HERO Wired Gamer Mouse. Unifying Software from the Logitech website . The receiver operates at 2.4 GHz.
Autonomy
In terms of autonomy, AA batteries have a battery life of 18 months for an average use of 2 hours per day. You can extend this battery life by turning off the K400 Plus keyboard when not in use. You can use the ON/OFF switch on the keyboard for this purpose.
Compatibility
As for compatibility, the K400 Plus runs on Windows 7 or later, Android 5.0 or later, and Chrome OS. The K400 Plus keyboard is even recognized on a PS4 console and an IPTV box. It should be noted, however, that on PS4, the keyboard is recognized without the touchpad.
The switches used on the K400 Plus are flat membrane switches. They are quite wide, but more or less hard to press. The enter key is also too small for our taste. It's a bit laborious to find it in use blindly. The keys are nevertheless durable, as each of them supports 5 million keystrokes .
Logitech options
For easier and more in-depth configuration, you can download the Logitech Options from the manufacturer's website. It allows, among other things, to directly detect paired Logitech peripherals and configure the multimedia buttons present on the K400 Plus. This software allows you to change the sensitivity of the touchpad and configure multi-finger functions (scrolling, zooming, etc.). In Logitech Options, you can also activate a notification so that you are alerted when the battery life level is low enough.
One of the negative points noted on this keyboard is the fact that there is no indicator when the capital letter is activated. This keyboard is not as backlit and does not have an RGB LED system. If you want a keyboard with this lighting system for more immersive gaming, you can opt for the Logitech G915 Gaming Wireless Keyboard . The latter costs around €249.
