Customer Ratings & Reviews

Works great. Keys have decent feel, includes both the keyboard and a track pad, and is wireless via USB. The USB receiver tucks in the battery compartment when not in use. It is small, as seen in the photo next to my full-size Logitech MX Keys keyboard. Fits in my backpack when I need a better keyboard than the ones in my office. Also, it works great with my Raspberry Pi.

Great compact keyboard, helps a lot with typing emails and passwords for my Xbox. I love this keyboard.

Plug and play. Used to control laptop that is wirelessly connected to TV from other room, about 15ft away. No issues. 2 finger drag to scroll, and tap to click on touch pad. All the features desired in small sturdy keyboard.

I personally use this keyboard for in office days! It’s perfect for loading up and taking into the office! It’s so compact but still works better than a laptop keyboard! I’ve had no issues with it!

Great little keyboard. Purchased to use with my racing simulator rig, and it's perfect to grab with one hand or sit on my lap. Also works great for watching shows/movies and not having to walk back and forth to the computer. Only nit-pick is the lack of scrolling bars on the touch pad but not the end of the world. Obviously not a super responsive gaming keyboard, but that's not why you should buy it.

This little keyboard is perfect for my legion go! A+ It takes up very little space & looks great.

I love the fact that it is a small keyboard and fits in my backpack. It works great and the keys have a great smooth feel when typing.

I love this keyboard I place my laptop on a monitor and use my keyboard to have some distance and help relieve tech neck

This is a great, compact keyboard for anyone who wants to hook up their computer to their main entertainment display. The left click button on the upper left hand side of the keyboard allows you to hold the keyboard kind of like a controller. This was really smart design, especially for web browsing and navigation. Typing with this on your lap is a bit of a challenge, but I went in knowing that navigating my desktop from the couch was going to have a few drawbacks and wasn’t disappointed with the compact size.

I use this for my home arcade, it’s small and works great.

This keyboard is nice and small and easy to use while lying in my bed.

I recently purchased a Steam Deck and needed an easy way to type and click on items when using the Steam Deck in desktop mode as it's track pads take some getting used to. I originally thought of getting a separate wireless mouse and keyboard combo but decided to save some space and get this in stead. Just plug in the reciever into your dock used for your Steam Deck, pull the plastic on the batteries, flip the switch to on and off you go. No drivers needed it works right out of the box. It is a little longer than the Steam Deck and slightly wider as you can see in the photos. This allows you to save a little room on your bag since you don't need to have a mouse and it reduces the weight a little as well. Over all this is a good investment for those looking for a good keyboard to use with the Steam Deck.

I bought this keyboard for an LG OLED Smart TV. Super easy to set up and works great... mostly. Unfortunately the YouTube app will not allow text to be input from any keyboard - everything else works fine, but not alpha text input. An internet search reveals this is a common problem across TV brands and is an asinine choice by Google in their app, not a fault of the tv or keyboard. The mouse pad works just like the 'magic remote' that came with the tv, so this is actually a backup to the remote if anything ever happens to it, at a lower price. The keyboard itself is light and compact and thin. I haven't tested the range, but it's fine roughly 10 ft from the tv, with the USB fob inserted on the back of the tv. One minor nit: the USB fob is kind of hidden in the packaging and the instructions are not terribly clear. This wasn't a big problem for me since I knew it exists and must be around somewhere, but my parents would have been utterly lost.

I use this keyboard for my shop computer. The bench space for the computer is limited so this keyboard fits the bill. The desktop PC I use is an older self build but it works without flaw with the USB Logitech wireless plugin. I was able to clear bench clutter with the smaller keyboard and elimination of the mouse. Everything stores on top of the computer when not in use. When working on cars and motorcycles it is very convenient to bring the keyboard to the vehicle when doing diagnostic tasks. Range is very good and the battery life so far is excellent. I just switch the keyboard to off when not in the shop so it should go a long way in battery life. Typical Logitech quality, accurate touch pad and the keys seem well designed.

Review of the Logitech K400 Plus TKL Wireless Membrane Keyboard – A Compact Giant in the World of Peripherals In the boundless cosmos of peripherals, where innovation is often dwarfed by impracticality, Logitech has delivered yet another masterpiece that dares to challenge convention. The Logitech K400 Plus TKL Wireless Membrane Keyboard, with its built-in touchpad, is not merely a keyboard; it is a gateway to seamless convenience, a confluence of form, function, and finesse that redefines the concept of wireless control. Designed for a world where the boundaries between devices blur and multitasking is the norm, this keyboard stands as a paragon of utility. It is not just a tool; it is an experience—a tactile symphony that harmonizes with your PC, TV, laptop, or tablet. From its meticulously engineered design to its unmatched versatility, the K400 Plus is more than a peripheral; it is a companion. Unboxing: The Prelude to Greatness From the moment you lay eyes on the K400 Plus’s packaging, you know you are in for something extraordinary. The box itself is minimalist, exuding Logitech’s signature aesthetic—a commitment to design without unnecessary embellishments. Upon opening, you are greeted by the keyboard, resting like a crown jewel. Inside, you will find: • The keyboard itself, sleek and understated. • A USB receiver, small yet mighty, ready to forge the connection between devices. • Batteries already installed, a thoughtful touch that underscores Logitech’s attention to detail. • Documentation that is as concise as it is clear, ensuring even the most technologically averse can get started effortlessly. The unboxing experience, though brief, sets the tone for the journey ahead. Design: Compact Yet Commanding The Logitech K400 Plus is a triumph of industrial design. Measuring a modest 13.9 x 5.5 inches, it is compact enough to rest on your lap yet spacious enough to type comfortably. The keyboard embraces the TKL (tenkeyless) format, eschewing the numpad to achieve its streamlined form—a decision that speaks to its versatility. The black matte finish is both elegant and practical, resisting fingerprints and minor smudges. Every curve, every corner, every detail has been meticulously crafted to balance aesthetics with ergonomics. But it is the built-in touchpad that sets the K400 Plus apart. Positioned on the right side, it integrates seamlessly with the keyboard, offering precision control without the need for an external mouse. Its size, 3.5 x 2 inches, is perfect for multitouch gestures and cursor navigation, making it an invaluable asset for those who value simplicity. Wireless Connectivity: Freedom Redefined Here lies the essence of the K400 Plus: its wireless functionality. Utilizing a 2.4GHz connection via the Logitech Unifying Receiver, this keyboard eliminates the clutter of cables, offering a connection that is as reliable as it is responsive. The range, an impressive 33 feet (10 meters), ensures that you can control your device from across the room—a feature particularly appealing for those who use their TV as a media hub or their PC as a home theater system. Pairing is effortless, requiring nothing more than plugging in the receiver and flipping the switch on the keyboard. Logitech’s proprietary wireless technology guarantees minimal latency and interference, ensuring that your commands are executed with precision. Typing Experience: Membrane Magic The K400 Plus employs membrane keys, striking a balance between quiet operation and tactile feedback. Each keystroke is soft yet satisfying, with enough resistance to prevent accidental presses but not so much as to cause fatigue. The keys are well-spaced, accommodating users with larger hands while remaining compact enough for portability. The inclusion of media-specific keys—volume control, play/pause, and more—adds a layer of convenience that elevates the typing experience. The layout, though compact, is intuitive. The absence of a numpad might deter accountants, but for the vast majority of users, it is a worthy compromise for the keyboard’s portability. Touchpad: A Game-Changer The integrated touchpad is not merely an afterthought; it is a masterpiece in its own right. It supports multitouch gestures, including scrolling, swiping, and zooming, making it a versatile tool for navigating modern operating systems. The touchpad’s responsiveness is remarkable, rivaling standalone trackpads in its precision. It is especially useful in scenarios where space is limited, such as on a coffee table or a crowded desk. The physical buttons beneath the touchpad offer a satisfying click, providing an alternative for those who prefer tactile feedback. Battery Life: An Endurance Champion Logitech claims an astonishing 18-month battery life for the K400 Plus—a bold assertion that holds up under scrutiny. Thanks to the efficient use of power and the inclusion of an on/off switch, this keyboard is a true endurance champion. For casual users, the need to replace the batteries might occur once a year, if that. For heavy users, the longevity is still unparalleled, ensuring that the keyboard is always ready when you are. Compatibility: Universal Appeal Whether you are connecting to a Windows PC, a Mac, a Smart TV, or even a Raspberry Pi, the K400 Plus is up to the task. Its plug-and-play functionality means you can transition between devices effortlessly, making it a jack-of-all-trades and master of many. The keyboard is particularly well-suited for Smart TVs and media centers, where its combination of keyboard and touchpad eliminates the need for multiple peripherals. It is equally at home on a laptop or tablet, where its portability shines. Durability: Built to Last Despite its lightweight design, the K400 Plus is surprisingly robust. It can withstand the rigors of daily use, whether that means marathon typing sessions, frequent relocations, or the occasional drop. Logitech’s commitment to quality ensures that this keyboard will serve you faithfully for years to come. The Intangibles: A Philosophy of Convenience To use the Logitech K400 Plus is to embrace a philosophy of convenience. It is not the most advanced keyboard on the market, nor does it strive to be. Instead, it excels at what matters most: reliability, simplicity, and versatility. In an age where devices become increasingly complex, the K400 Plus is a reminder that great design is not about adding features but about perfecting the essentials. Conclusion: A Perfectionist’s Dream The Logitech K400 Plus TKL Wireless Membrane Keyboard is a triumph of engineering, design, and practicality. It is a product that understands its audience, delivering exactly what is needed without unnecessary frills. For those seeking a keyboard that can transition seamlessly between devices, offer unparalleled convenience, and perform reliably in any scenario, the K400 Plus is an obvious choice. Is it perfect? Perhaps not in the absolute sense. But in its category—a compact, wireless keyboard with a built-in touchpad—it is unrivaled. To own the K400 Plus is to own a device that enhances not just your productivity but your enjoyment of technology itself. It is more than a keyboard; it is a testament to the power of thoughtful design. Five stars, because six stars would defy logic—but this keyboard deserves them nonetheless.

My brother and I are gaming nerds and we've been caliing the K400 "The Greatest Keyboard Ever Made" for more than a decade. This little keyboard has seen me through grad school and now sits in its rightful place on my Sim Rig. Its so nice and I'm so lazy that I'm going to buy a 2nd one just so I can use my laptop while lying in bed.

I'm using this on a server so the compact size and built in touch pad is a great feature. I simply tuck it on the side of the sever and pull it out when I need to use it. It says 18 month battery life and I can't confirm this but I have other logitech products and those easily last a year or two so it seems likely. The key stroke feel is not as clicky as I prefer but since I will only use this thing once week or less it's not a big issue. Connectivity was simple, just plug in the dongle and it was working, no paring or setup required. I think I only paid around $29 which is a bargain. One issue I had was I thought the USB dongle was missing, it was not in the normal slot in the battery compartment. I looked all over for it and was getting mad that I would have to return to the store, but it was tucked into a box which was actually hard to see. they should improve the packaging.

Recently built a new gaming PC, so I took my old one and moved it to the living room and hooked it up to my TV. This way I can use it to stream Netflix, Crunchyroll, or whatever. That way I can use my VPN to get around region locked content. Anyway, I needed a wireless mouse and keyboard obviously in order to actually do anything on my PC and since I'm not planning to really game on it anymore (if I do I'll just use an Xbox controller) a touchpad works just fine. This allows me to use my PC from the comfort of my couch, and being an all in one device it keeps me from having to look for anything and it's the perfect size that it won't get lost or take up too much space.

This keyboard is perfect for couch use with good range and battery life. It's also small, thin, and light. The multitouch capability of the TouchPad is also a nice feature.

This is the 2nd one I've owned - I love this!!! I'm only 5'2" and have smaller hands. It's so easy to use this, It's compact, so when reaching for the wireless mouse I use with it, I don't have to stretch over a numbers pad. Plus, with it being wireless, you can position it just how you want for comfort. I wouldn't be without it. It's well made, my last one lasted about 10 years or so, and I used it 8 hours a day. I'd definitely recommend this product
