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!

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.

Cordless keyboards and mice originally used to be a royal pain - always needing fresh batteries or recharging, usually when finishing something urgent! Funny battery types in them, often enough to annoy. Unreliable, too. But not this one! Battery life is good, and it works as reliably as a corded keyboard. It is fine for web surfing as well as long typing sessions. The two original vanilla 'GP brand' AA cells are still showing as good on my tester after six weeks - which included all the Christmas eMails and ordering, thank-yous and so on.... The keyboard itself feels good; not the absolute bestest ever, but good for typing at my own top speed of about 35 wpm. I like it! There are not really enough keys, so one needs to do (eg) 'function-backspace' in order to do a 'PrintScreen', and the tiny grey-on-grey 'Function' key icons are close to illegible, even with my new vari-focal glasses. They are the sort of icons whose intention is only clear _after_ you look it up! The sort of Icons that resemble (in function) the legal font "Enron Beelzebub" often used for the obfuscated fine print on contracts. The track pad is indeed OK. I get on fine with track pads - people who do not (like my wife) will (of course) hate it. Just saying... I do the odd bit of CAD editing for the 3D printer on this machine, and it's fine for that. Not as precise as our vintage trackball, but that would not be expected of a vanilla track pad. My pet peeve is the on-off switch, which is sensibly arranged to not be easily operated accidentally, but it is so tiny that only my little fingernail gets close to fitting it. But I do use it (pretty) religiously, turning off at night, or when we go out. If you can handle a track pad, this is an OK keyboard/track pad combo, a tad expensive, but it seems to be good quality. Recommended - but do read the edit below! EDIT - JAN 2023 OK, it got wet (a burst pipe) - so did the PC and the screen. But after long hairdryer and fan-heater sessions, all three are now working again. I confess to buying another keyboard - the Rii K22, which is rechargeable, turns out it types better for me, has a distinctly better track-pad and is cheaper! The K400 is OK, but the Rii K22 does suit me better. Did you know that this K400+ has a little slot in the battery lid which takes a USB dongle? No, I didn't know that, either. Sadly, it seems as though the dongle is bigger than it was back in the early days, since the battery lid will not fit back on if the USB dongle is in the slot! D'oh! <sigh> The Rii K22 has a neat slot for the dongle that does fit! Just saying . . .

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 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.

Compact yet still great keyboard for typing or sofa surfing, and the track pad is good too. I have tried the much smaller devices and find them simply not useful. Works straight out of the box. Full marks.

First, the positives. It's surprisingly heavy and well put together, giving a quality feel, and the key action is very positive. The key layout is slightly different to the old version - the good news is the power button has been moved and it's far less likely to be caught accidentally. However the trackpad is a piece of garbage. It's too sensitive one minute, and doesn't respond the next - there is no way to adjust the sensitivity in the Options app. You can adjust the mouse and scroll speed - mouse speed is currently OK at 5% (Yes, 5%), but scrolling is turned all the way down to 1%, and you still see the bottom of the page as soon as you try to scroll. Also, it's NOT BLUETOOTH! You have to use the proprietary USB dongle. I very much regret this purchase.

Really decent keyboard for the price. It isn't the cheapest you can get but it is Logitech and I think they make good, solid devices. I don't have any negatives to say about it except for the very important little dongle is hidden in the edge of the box, making it very easy to miss if you don't look. Otherwise, it's fantastic. I use this with my nVidia Shield device, plugging the dongle into the system and it just works out the box. Having a trackpad makes it great for being able to get to things quicker than with a remote. It's lightweight, easy to set up and looks pretty good. I like the slate grey colour with little yellow accents. The typing feel is okay, I wouldn't really use this as a main device for gaming or long typing sessions but it's great for just pulling out when I need it. At £44.99 I wouldn't want to pay any more but I got it on say for £23.99 with 47% off which I think is a great price.

I like the keyboard. Thanks.

The page say rechargeable, it requires AA batteries. Other than thst a good cheap wireless keyboard.

Received in worst condition.

plus pratique que le clavier du laptop. surtout pour une journee de teletravail. attention le clavier est légèrement plus petit que les filaires qu on nous fournit au bureau. il faut s habituer. bon rapport qualite. bon signal, ca marche bien a distance

Beautiful product, comfortable to use and light weight
