Just buy it
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 lifeExtremely durable (survived years of couch use)Plug-and-play reliabilityCons:None.

Great little wireless keyboard to watch TV with.
I really like this keyboard. I have a Walmart branded Chromecast device on my TV. With that brand, you can buy a USB adapter that allows you to connect ethernet and a USB A device. I plugged in this keyboard (wireless) and it worked straight away. I didn’t configure anything. Watching Prime TV? Wanting to search for your favorite show? Use a keyboard instead of your remote. Much faster, more comfortable and with the track pad, you get the bonus of a mouse pointer. It’s big enough to type with reasonable comfort but small enough to stow away while watching your show(s). I’ve had this unit for more than a few months and I’m on the same set of batteries. I expect that it has a long battery life. While made of plastic, it does not feel flimsy to me in any way. It’s a great little keyboard for this application in a media room.

Good luck to gaming peripheral companies making a better keyboard than this one.
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.

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.
