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

I had an older Logitech keyboard that I was using with my Raspberry Pi but I had to use a mouse with that one, plus the keys required too much pressure for a touch-typist, and so it was not very comfortable. This keyboard is much more comfortable. The keys really feel great. The keyboard does feel and look a bit cheap, but, well, it was inexpensive, and I think it looks and feels and works great for the price. No complaints. It is full-size and yet small and light, and I love the tack pad. It is great not to have to use a mouse. It works fine with Linux, but Linux is not listed under supported OS's because you would not be able to use the optional software that you are extremely unlikely to need. You would need software if you want to attach multiple Logitech devices to the same Unifying wireless dongle (and if you really need to do that, I'm pretty sure you could use a Windows machine to set it up, and then use the dongle with Linux -- at least I could do that in the past). You could also use multiple dongles, one for each item, but that wastes USB ports. I like Logitech's super-simple plug-and-play Unifying wireless setup, but it is not Bluetooth that you could use with most tablets or phones, so keep that in mind if you are considering this. You need the tiny USB dongle that comes with the keyboard. Think of it as being a USB keyboard minus the wire. The battery lasts a super, super long time (it will probably age and go bad rather than being consumed from usage -- you'll have to remember to swap it out after a year or so). The keyboard has an easy on-off button and that also helps the battery last a long time. Great item.

I bought this keyboard back in 2019 for my living room media setup, and strictly speaking, this is one of the most useful tools I have ever purchased. Here is why it earns a perfect 5 stars: Insane Battery Life: I am not exaggerating when I say this thing hardly ever uses batteries. In the 5+ years I’ve owned it, I can count on one hand the number of times I've had to swap the AAs. It just keeps going. Reliability: It has never failed. Not once. No connection drops, no lag, no stuck keys. It just works immediately every time I pick it up. Perfect for HTPC/TV: Having the built-in touchpad is a game changer for controlling a PC connected to a TV from the couch. It’s lightweight, comfortable to hold with two hands, and the media keys are exactly where you need them. If you need a keyboard for a home theater PC or smart TV, just buy this. It is the gold standard for a reason. Pros: Unbeatable battery life Extremely durable (survived years of couch use) Plug-and-play reliability Cons: None.

First off this keyboard performs fantastically. I like the touchpad it's responsive. And I like the keys they're a little squishy but they fire and they work. I bought this keyboard to work with my steam deck. It will work with pretty much any handheld that you connect to it. But you're going to need some kind of dock in order for it to work because it includes a IR or whatever we had before Bluetooth connector that you have to plug in. So this means if you are buying this for your steam deck you will not find it in your Bluetooth options. It means that it only works when it's plugged into your deck. Other than that connectivity is a snap it doesn't require any extra downloads. It even works with Linux seamlessly. That being said, given that I live in a dark apartment and I have not been able to purchase extra lighting, a lighted version would probably be a good idea. That being said overall it is a good keyboard and does what it needs to. That being said it is not the type of equipment that I would probably want to trust with my life. So taking it on any ill-fated submarine rides is probably not a good idea. I would probably trust it if I needed to contact emergency services with it though. It's solid enough. And in a society where everything is built to make a profit, I think that's very important to remember. You want things to last you don't want things to break down the moment your warranty runs out. Again in terms of appearance the gray color doesn't really bother me all that much. The fact that it's not very well lighted matters to me. But I think that RGB on a wireless keyboard is pretty silly, Microsoft did it once or twice but I think I had to recharge that keyboard thousands of times because the RGB would just suck up so much power. I think a low-powered lighting that was still bright but required less energy would probably be helpful. Probably ideas for future keyboard designs for companies to mull over. I wish them luck in making a better keyboard then this one. Maybe that in itself is what you needed to hear. Good luck to companies making a better keyboard than this one. Because it's solid.

Do not understand any bad reviews. I use it like normal, no issues at all. Works perfect. Good size, just right. Worth every cent but a little expensive. Trackpad works flawlessly. Fast typing. Has taken a lot of falls, no damage.

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.

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.

The logitech K400 is my go to when I need a quick keyboard to use with a TV or any non computer application. I own 2 and bought 3 for the conference rooms at work. Battery life is great, light weight, has a track pad, good quality, and inexpensive. I've generally had good experiences with Logitech products and this is no exception.
