Logitech K400 Plus Wireless Touch TV Keyboard with Easy Media Control and Built-in Touchpad, HTPC Keyboard for PC-Connected TV, Windows, Android, Chrome OS, Laptop, Tablet - Black

Just had it delivered a few hours ago. Tried it with my mobile (had to get a small OTG adaptor to get started). I also own the K480, and got this one because it has a touchpad. Comparing the two, both have unique features that I would not call positive or negative, because how one views a feature, or the lack thereof, depends on one's requirements. The plus-point of the K480 is that it connects through bluetooth, leaving the port free to charge the mobile (if you want to use it with your mobile/tab) or connect a pendrive to it. The keys are larger and better spaced out (important if typing comfort is a major priority). The K400 plus, on the other hand, requires the OTG adaptor, plus, the unifying receiver used to connect the keyboard to devices like the mobile, tab, or the LCD TV. The plus point of this feature is that connection is immediate. The minus point is that one must be careful not to lose the 'unifying receiver'. Also, if you forget the OTG connector, there is no way you can connect the keyboard to anything. The 'K400 Plus' is also lighter and slightly tinier: But comfortable enough for normal to large sized fingers to type without any obstacles. Unlike the K480, this piece has the touch pad. One main advantage of going for these keyboards ( be it the K480 and K400) is the amount of money saved...in my case, I saved 28K approx., the amount I would have to invest for getting a new laptop. And just didn't have the money to invest in one. Now, with this, I can complete most college assigments. And a couple of years later when my phone conks off, I can simply get a new smartphone for about 8-10K. If one calculates the interest accumulated, one has way more in one's hand than one thinks.

So I would probably assume most people would be using it for their smart TVs but for those who are looking to buy this because of its compact design and touchpad integration to carry with a laptop or use it on a general-purpose PC. Here are some important things to note before buying - The reason being why I bought this keyboard is to use it with my laptop since 1. it is compact as what I would wanna look for, 2. it has the mousepad integration so I wouldn't have to use my hand all the time reaching a mouse or the trackpad on my laptop itself. (My laptop keyboard broke, so I'm using this one) Now getting it in hands reveals that some things: 1. The build quality feels very cheap not certainly not of this price range 2. It doesn't have any LEDs as a sort of indicator of battery, capslock ect. Which you make like or hate, I hate. 3. The trackpad is small which is okay since it is meant to be compact but the touch is significantly worse than my laptop, especially the swipe sensitivity. 4. The swipe gesture direction is opposite to what the default one is for the windows precision enabled trackpads. 5. Last but not least, you will need some time getting used to using the backspace and other keys on the right column keys because of being it shorter than usual. I mentioned all the bad stuff about this before the good ones because that's what I think is more important for an average consumer like you. I'm not being sponsored by them so it's okay. Now, let's go on to some good stuff about this keyboard. 1. Typing on this keyboard feels better than the default laptop experience 2. Runs off of AAs, and it lasts pretty long. 3. The shortcut keys are just awesome for just about any device.

Logitech K400 Plus Wireless Keyboard is one of the best wireless keyboards in its class. I've been using it for the past couple of weeks and it's been an amazing experience. So, as usual, let me start with the pros and cons of the product Pros - ==> Plug and Play. ==> It's wireless so you can keep your laptop at one end and operate it from another corner. (You gonna get lazier than you already are) ==> Unifying the keyboard and touchpad make it more convenient than having a combo of wireless keyboard and mouse. ==> Keystrokes are not very noisy ==> Gesture are really very convenient and better than my laptop touchpad(they have used/copied some of the Mac's features in the keyboard) ==> Compact and slim design gives it a premium feel ==> Light weight make it easier to carry around ==> Ability to change the function keys. You can use it as the standard F1-F12 keys or change it. Though you will have to install Logitech options from [...] it will also help you tweak the setting like: - Keyboard - Point and Scroll - Gestures ==> Placement of the Volume keys ==> If you own multiple Logitech wireless Bluetooth devices, you can easily connect it to the Universal receiver that comes with the keyboard Cons - ==> Using the keyboard at night without lights is a big issue ==> Keys like Num Lock, Print Screen are missing Initially, it may take some time getting used to it but once you do surely it would be an amazing feeling to use it. Truth be told I was very skeptical about buying a Logitech product which carries a price tag of 2K+, but it was worth the try. Note: Till now I've used the product only on Laptop and Desktop so I'm not quite aware of its performance on other devices. Also, it's been only a couple of weeks to talk about the battery life so I skipped that part. Once I do I'll update the review.

As expected the product is good ✨ I am using it no problem working fine and good . Hope the same ☺️ I purchased it at 3.7K I would say it totally vrat the price the prices fluctuating from 3.22K to 3.7K so check when the price is dropping or you might purchase at the same price where I have purchased this thing 😅 Overall the product is good not complaint about the product but the prices likely higher side because at this price you would better get an mechanical keyboard but the main feature in this keyboard is keyboard and the mouse pad so this is the highlight selling it High 🥵 But totally worth every penny which I have spend in the product ❤️❤️

I bought this keyboard as an accessory for my MacBook Air last month as a part of my WFH set up. I have a wireless Logitech mouse (M590) and so I wanted to buy a Logitech keyboard to have a unified device USB for both the peripherals. Considering the type of my usage, I zeroed in on this keyboard even though it was expensive. First impressions: The build quality is not great for the price it is offered but its lightness proved to be a blessing in disguise.. It connected seamlessly with the Mac as soon as I switched it on though the description said that it was mostly compatible with Windows and Android devices. Keyboard: As far as typing is concerned, it took me a while getting used to as the Mac keyboard does not have as much travel. However now I find it very convenient to use. Trackpad: One of the reasons I wanted to buy this particular model was the availability of the trackpad. I thought it would be very useful considering I use the trackpad on the Mac a lot. However, the trackpad is very slow as compared to Mac's and I rarely use it. I use a mouse instead. Problems After one month of usage, I found the following problems. Every time I booted up my Mac and connected the keyboard, it would not work properly. The keystrokes would type extra characters (see image attached). If I typed "o" it would print "qo" instead. If I typed "p" it would type "xp" instead. Similarly if I wanted to type Shift+p, it would not print anything at all. However after several switching off and on of the on button, and after 10 minutes or so, the problem goes away. But till that time, it is really frustrating and I have to switch over to my Mac keyboard instead. I have raised a ticket with Logitech and they referred me to the cleaning process in the support forums. I have already done that several times but the problem doesn't seem to go away. It could be just a problem with my unit. I am not sure if it is a known issue for other users of this keyboard but nothing (including a firmware update) seems to work.

I'm using it with my home music studio. Compact and very good. Connects immediately, no driver required. Works with my Bravia 43 inch too. Wish it had a trackpoint or maybe the touchpad was in the middle so that the keyboard would be split (with keys like B, H, etc occuring on both sides).

Good little keyboard from Logitech. The size of keyboard is very compact, infect maybe too compact for some. Touch pad is great and works well with PC running Windows 10 as well as Apple Mac OSX. Which was a surprise because Mac compatibility wasn't mentioned on the box. However support for android device is mentioned on the box but I haven't tested that yet. Touch pad supports single tap to click and double tap to right click as well as gestures like two finger scroll and pinch to zoom. Plus volume keys on the top of touch pad is a great edition. Three gaming keys are awkwardly placed so not very ideal for gaming. The range is good and keyboard and mouse doesn't lag like other cheap wireless products. Only issue here is the build quality. Keys feel bit flimsy and overall plastic feels like it could easily break. There are keyboards out there that cost much less but have lot better build quality. Overall a good product for home media center use. I am using this keyboard to control my PC connected with my HDTV, from comfort of a couch. Keyboard comes with two batteries right out of package so you don't have to rush and buy new ones immediately. Delivery was quick and packaging was excellent.

I don't like the product received yesterday, spoken with Amazon customer care they told that refund can't be done by Amazon team, given Logitech Customer Care today I have spoken to Logitech Customer Care team they told we can't provide refund or exchange only Amazon can do from their side. Both platforms are not responsible then why to keep the product for purchase to customers...?

Logitech K400 Plus Wireless Touch TV Keyboard Review The Logitech K400 Plus Wireless Touch TV Keyboard works flawlessly with the Nvidia Shield Pro. Setup is incredibly simple—just plug the USB receiver into the Shield Pro, and you’re ready to go. No complicated installations or software are required, making it a plug-and-play solution for any home theater or media center setup. One of the most impressive aspects of this keyboard is its responsiveness. There is no delay in either typing or mouse movement, even when navigating menus, typing in search fields, or browsing the web. The touchpad is smooth and precise, ensuring that you can control the cursor just as easily as you would on a desktop or laptop. This level of performance is crucial for a seamless user experience, and the K400 Plus delivers it without a hitch. Another standout feature is the battery life. Logitech claims up to 18 months of battery life, and based on my experience, it’s spot on.

Overall, the Logitech K400 Plus Wireless Touch TV Keyboard is a highly reliable and efficient accessory for the Nvidia Shield Pro. It offers a simple setup, fast and precise performance, and excellent battery life. If you're looking for a no-fuss, responsive keyboard and touchpad combo for your home theater or streaming setup, this one comes highly recommended.

I have two 6 Series (MU6290) 40" Samsung 4K Smart TVs that I purchased at Costco, one in my office and the other in my master bedroom. For about $19 I purchased a wireless keyboard and mouse combo on Amazon to use with the TV in my office. They use a single unifying USB reciever and work great, just plug and play. The only thing I found I didn't like was having two devices to keep track of and having to switch between them to point and input data. I saw this keyboard as an Amazon Deal of the Day two days ago and just received it, in fact I'm writing this review with it while sitting on the bed and using my bedroom TV. It turns out to have been a very good purchase because it works great! I merely plugged the unifying USB receiver into the first USB input on the back of the TV, turned the keyboard on and started using it, true plug and play. And boy do I love using the touchpad to cursor around instead of having to switch between the keyboard and mouse like I do in my office. In fact, even though the keyboard and mouse work fine on the TV in the office, I may end up buying another K400+ to use in the office, it's "that nice" not having to use two devices. I know the K400+ is advertised as a device for using with a computer connected to a TV but I read other reviews where it was being used directly with a smart TV without a computer and, even though it works great with my Samsung, I can't speak to whether it works with all smart TVs, though I expect it should work with any of the later Samsung Smart TVs which use Samsung's Tizen OS. I don't know if it works with the other two major Smart TV operating systems, WebOS & Android. It's light, seems well made, has a QWERTY keboard with nice key response and feel and is spaced fine for touch typing. It's great for basic input and I'm finding out more about how it functions with my TV. For instance, I found out holding down the CTRL key while cursoring moves the cursor one word at a time, holding down the SHIFT key while cursoring highlights one letter at a time, holding down the SHIFT + CTRL keys while cursoring highlights one word at a time, etc. These are familiar, however I've discovered by playing around that other keys and key combinations do things but the result may not necessarily be what I expected, but I'm the type who likes to play and learn and will thus get even more use from this keyboard as I learn. For example, just discovered esc key is equivalent to the "back" function when used in your browser. I can mention the media keys, previous chapter, next chapter, pause/play, volume up & down don't work with my TV. I'm sure they do if the keyboard is connected to a computer that's connected to a TV, as advertised. However this keyboard is perfect for anyone who only simply wants to point and input, especially if you only want to use one device! Overall I'm "extremely pleased" with the K400+ and am so glad I decided to give it a try. Of course the only thing I can't comment on is it's longevity but I hope it lasts a good long time because I love this thing!

Very useful keyboard for a media centre PC. Very handy having both the keyboard and trackpad in one unit rather than trying to find a surface to use a mouse on. Keyboard is good to type on. The unit as a whole feels solid but the plastic it is made out of seem quite cheap - which the product definitely was not! So the prices Logitech charge are a bit high but its the only media centre keyboard on the market so you just have to deal with it.

Very important detail. You would expect the dongle to be in the battery compartment, but it is actually on a flap on the box. Seller was very polite and helpful when I enquired about it. On an unrelated note, this keyboard works with the Logitech Options software, but Logitech Options, the program to configure the keyboard does not seem to work with Window 11. Just something to be aware of. The keyboard and trackpad will still work, only there won't be a way to reverse two finger scrolling direction. That is a Logitech issue.
