Logitech K400 Wireless Touch Keyboard - Black

This Logitech keyboard works perfectly—comfortable keys, smooth touchpad, and a strong wireless connection. Just a small tip for new buyers: make sure to check the box carefully for the USB adapter. It’s not inside the keyboard, so don’t miss it. Overall, an excellent choice for TV or PC use!

I picked this up on 26 May 2025 and it’s been brilliant so far. The Logitech K400 Plus is lightweight, responsive, and really handy for controlling my PC-connected TV from the sofa. The built-in touchpad is a huge bonus — no need for a separate mouse, and it works smoothly. Setup was instant. Just plugged in the USB receiver and it worked straight away on both Windows and Android devices without needing to install drivers. I haven’t tested it on an Android tablet yet, but if it’s got a USB port or you use an OTG adapter, it should work fine. The keyboard is comfortable to type on for casual use like web browsing, emails, and media control. Battery life seems solid so far — still on the first set of batteries. If I had to be picky, I’d say it would be nice if it supported Bluetooth too for even wider compatibility. But for the price, this is a cracking little keyboard for media setups. Highly recommended if you want something simple, reliable, and portable

I’ve been using the Logitech K400 Plus Wireless Touch TV Keyboard for a while now, mostly for controlling my smart TV and media center, and overall, it’s been a solid choice. It’s a great budget option for those looking for a simple and reliable keyboard for their TV setup, though there are a couple of things that could be improved. Here’s my breakdown: Pros: Wireless Convenience: The wireless connection works flawlessly. I have no issues with lag or dropped signals, even when using it from a distance. The range is excellent, and I can comfortably control my TV from across the room without any problems. Built-in Touchpad: The integrated touchpad is a huge plus. It’s really convenient for navigating through menus and apps on my smart TV without needing a separate mouse. It’s easy to swipe and click, which makes it feel like a mini remote control. Compact and Lightweight: The keyboard is small and lightweight, which makes it perfect for use on the couch or in bed. It doesn’t take up too much space, and it’s comfortable to hold, unlike bulkier keyboards that can be hard to maneuver in front of a TV. Long Battery Life: The battery life is impressive. I’ve been using it for weeks without needing to change the batteries, and the auto-sleep feature helps conserve power when it’s not in use. Affordable Price: For a wireless keyboard with a touchpad, the price is very reasonable. It’s a great value for those looking to add convenience to their TV setup without breaking the bank. Cons: Touchpad Could Be Better: While the touchpad is a great idea, it’s not as responsive or precise as I’d like. Sometimes the cursor can be a bit jumpy, and it can be a little tricky to navigate with fine precision. It works well enough for general navigation but might be frustrating for more detailed tasks. Small Keys: The keys are on the smaller side, which is fine for general use but can be a little cramped if you’re doing a lot of typing. If you have larger hands or prefer a more traditional keyboard feel, this might not be the most comfortable option. No Backlighting: The keyboard doesn’t have backlighting, so using it in low-light settings can be a bit challenging. It’s not a dealbreaker for me, but it’s something to consider if you tend to use your TV at night in a dim room. Overall: The Logitech K400 Plus Wireless Touch TV Keyboard is a fantastic value for anyone looking for a simple and effective way to control their smart TV or media center. It’s compact, easy to use, and offers great wireless range. While the touchpad could be more precise and the keys could be a bit bigger, it’s still a solid choice for everyday TV navigation and light typing.

Pretty good. Does what it's supposed to do. I do find I'm always hitting the wrong keys when using somehow. I use it for a raspberry pi and it works great for that. It just works without any faff. The tracker pad seems good. The whole thing does feel a bit cheap, but the it was cheap really so I can't complain about that.

I've had these before so it says it all getting another. As well as the PC they are great for Smart TVs with the little mouse track on the side. Not too big and you can just leave them with you remote. Batteries last ages, nothing more I can say other than I've got about 5 of them now so it says it all.

This is about the fourth or fifth of these keyboards I have for different PC,s. Very handy. Good quality keyboards and batteries last to forever in them

This keyboard APPEARS to be very well made, & APPEARS to be unused, but as for how it actually works, & how long it lasts remains to be seen, so more about that below. I got it yesterday Wednesday 14 Nov (delivered by Hermes) from Amazon for £24.99. Delivered within about 24 hrs as I am a 'Prime' customer. As usual some delivery companies employees DO NOT treat the items they deliver with any respect at all! since the AMAZON beige box it arrived in looked like it had been squashed by something very heavy, as did the Logitech branded packaging inside the AMAZON packaging, that actually contained the keyboard. The 'yellow sticker' I have seen attached to this keyboard in youtube videos was NOT there, making me think that this keyboard may well be a SECOND HAND OR USED and RETURNED and resold as new item, especially considered the very poor condition of both the exterior AMAZON packaging & the LOGITECH branded box. When I pay for a NEW item I expect to get a NEW item. The battery life will probably reveal how old this item actually is since the batteries are supposed to last 18 months. Use with Sony Bravia Androud TV: In use (with a Sony 4k Android TV) it MOSTLY works as it should since it allows you to type letters for search much faster. It does not have a microphone button, but does not need one, since the Sony Remote has the Google Voice Assistant button. You will find that even when typing with this keyboard (the virtual keyboard still shows on screen) SOME functions (like ENTER) will not work properly (while viewing OPERA web browser pages), since you still need to use either the TV remote or the keyboard arrow buttons, to get the SAME item you want to click on (which IS highlighted when you get there with the trackpad, becuase the enter button still does NOT function in this scenario). This also means that the 'suggested' words that appear above the virtual keyboard will also NOT be selectable via the enter button if you highlight them by moving the cursor to them with the trackpad. This keyboard allows the arrow/cursor to be moved around VERY quickly AND SMOOTHLY with ONE finger, BUT to scroll properly in web pages, you still have to either use the TV remote or arrow buttons on the keyboard to move THE SAME CURSOR to the bottom of the tv screen. When scrolling with two fingers DOES work it scrolls far too quickly in big jumps so either move your fingers VERY slowly, with scrolling still being VERY jerky or don't bother. Therefore scrolling with TWO fingers DOES NOT WORK properly & only very erratically, since most of the time the trackpad does NOT react with two finger use, anyway. Also, this keyboard is a bluetooth item (as is the TV) but you still need to use the dongle for the TV to recognise the keyboards existence. When viewing the Sony Android TV interface, you CAN SEE AND MOVE the cursor around the screen, but enter does NOT work to select an item hovered over, because that item us NOT highlighted - therefore the Remote or keyboard arrow buttons have to be used. Use with Fire TV devices: If you try to use this keyboard with a 2nd Generation Fire TV device, it WILL work up to a point WITHOUT using the dongle. e.g. you can see a cursor on ANY screen including the home screen, but again the enter button will NOT select ANYTHING. Still WITHOUT using the dongle the keyboard arrow buttons WILL highlight items on the Fire TV home screen interface AND will get to 'settings' items, but NOTHING can be selected. This Fire TV device is a bluetooth device, but it will NOT find the keyboard, so you still HAVE to use thr dongle for better functionality. However TYPING DOES WORK, but WITHOUT the dongle the ENTER button does NOT work, at all. When typing with this keyboard the virtual keyboard does still appear on screen. When the dongle IS used then Enter WILL work (erratically). BUT the trackpad then DOES NOT, so you no longer see a 'cursor' and will HAVE to use the keyboard arrow buttons or 'Alexa Voice Remote to move around the Fire TV screen interface. When using a browser (like Firefox) with Fire TV, you DO see a smaller grey circle cursor as well as the big blue one, and you can move this little grey cursor - with the trackpad - but there is little point doing so since Enter will NOT work when hoverimg over an item with the grey cursor - you STILL have to use the keyboard arrow buttons or the Alexa Voice Remote, to highlight any item or link before you can select it with the enter button. The upshot of all this leaves me with questions: 1) Even though this keyboard (when dongle is or is not inserted), DOES have a small amount of cursor control via the trackpad, there is little point in this trackpad being there since very little is highlighted or even selectable with the enter or mouse buttons. 2) The volume & mute buttons above the trackpad DO work (with the Sony TV). 3) Why does a bluetooth enabled Sony 4k Android TV NOT detect this bluetooth keyboard without the dongle? 4) Why do I still need to use the dongle for the BLUETOOTH Keyboard to work, either erratically or NOT work at all with bluetooth enabled devices? 4) Why is SOME control possible of a Fire TV device, WITHOUT using the dongle? 5) Why does the trackpad of this keyboard show a cursor on the Sony Android TV user home interface (when using the dongle) & on the Fire TV user home interface (when NOT using the dongle), but still does not allow 'proper mouse control' including the use of 'selection' function via mouse buttons or enter whichever device I try to use this keyboard with? 6) Why is it that - when USING the dongle - that I can use the trackpad (ONLY in Firefox for Fire TV) but I then see TWO cursors (& the little grey one does NOT highlight links or items).?

The Logitech K400 Plus Wireless Touch TV Keyboard is a decent device, offering convenient media control and a built-in touchpad that makes it ideal for PC-connected TVs, laptops, or systems running Windows, Android, or Chrome OS. The design is sleek, lightweight, and easy to use, and the wireless range is impressive, making it a good option for controlling your system from the comfort of your couch. The touchpad is responsive, and the QWERTY UK English layout is practical and well-spaced, making typing straightforward. It’s a great choice for casual browsing or media consumption without needing a separate mouse or bulky setup. However, despite these positive features, the price is too high for what it offers. While it works well, it doesn’t feel premium enough to justify the cost compared to other budget-friendly alternatives in the market. If Logitech reduced the price, it would become a much more compelling option. Verdict: Not worth buying at its current price point.
