Lightweight keyboard. Quite small, I wish it was a bit longer. Seems to be good Logitech quality. I use it sometimes for my gaming computer which is connected to my television. Haven't had any significant lag or problems. The mouse pad works fine. I found a helpful tutorial online for the keyboard which helped me understand the mouse pad better.

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!

This wireless keyboard was purchased to control a mini computer connected to our audio/visual center, which is a limited use case, so our expectations aren't demanding. It works well for our purpose. The keys are nicely spaced for the limited typing we do, and the touchpad pad supports all of the necessary options and is easy to use with selections via either a tap on the pad or a mouse-key click. It is an attractive package and compact, which fits nicely into a easy chair pocket. It connects without issue across the room, and, so far, has exactly met the needed expectation of our use case. The easy sliding on/off switch is a nice touch to maximize battery life. I could easily have selected 5-stars, but, our is definitely not a very demanding case with modest expectations. I would buy this Logitech K400 Keyboard again.

Perfect keyboard and trackpad combo for a Linux HTPC. Allows me to remove my Roku from my TV stand and primarily use a PC as the source for everything. Being able to interact with full desktop applications instead of whatever app I needed to through a remote has been a game changer. As of writing this review, I am comfortably reclined and thoroughly enjoying the experience. The hardware itself feels somewhat cheap but it was a 20 dollar keyboard. Looking forward to using this daily for as long as it lasts!

This Logitech K400 Plus Wireless Touch has worked great for both my HTPC and a server setup, controlling media on one and handling occasional game/system control on the other. The built-in touchpad is a nice touch, no need to grab a separate mouse just to navigate around. Range and connectivity have been solid from across the room with no lag or dropped input. Material feels solid for a budget keyboard, not flimsy or cheap despite the price point. Noise level is low too, quiet keys that don't clack loudly, which is nice for late night use near others. Durability has been great as well, still going strong with no sticky keys or unresponsive spots after regular use. Compact and simple, exactly what you want for a couch friendly control setup.

The Logitech K400 Plus is a great addition to your multimedia TV setup when you set up a PC or Android TV. Rather than using the remote with Gyroscope to type out each letter to a show or movie that you are trying to find, This wireless keyboard makes it easier for you to type the words out at ease without fatiguing you arms when swinging them back and forth to each virtual QWERTY pad on screen. It also has a built-in track pad that is conveniently placed on the right side so you can not only use typing, but also cursor your way to specific buttons and search bar. It is packed with so many features that I find it useful in any way. I mainly use it for my Android Box, so the digital volume button and the back button has been used plenty of times for me and I didn't have to cursor my way down to the task bar to change the settings from there. The connectivity is pretty simple as you turn on the keyboard, plug in the USB dongle in the box, turn on your TV, and it should recognize immediately without any use of driver install. The size of this keyboard is around a 65% layout with an added track pad to the side. It is on the thinner side, so don't expect that the keyboard is made with quality as it does display creeking noises when pressed down. Speaking of pressed down, the key strokes are not mechanical and have a short travel. It feel very mushy when pressed, not the best keyboard per say, but it does get the job done. Battery life, is surprisingly very good as it lasted quite a long time for me, but your mileage may vary as I turn the keyboard off after every use to conserve battery. I like how the USB is conveniently place in the back cover inside where you access the battery compartment. Now, the reason, why I gave this keyboard a 3 star, is because of the way the keyboard felt. Although its features is a standout, it ruined it for me with the mushy keys. I'm also comparing this to the Logitech K600 that I also owned and that keyboard, although a tad more expensive, felt way better then the K400. Too bad, I don't understand why Logitech still kept this keyboard the K400 and discontinued the K600. There is no way you can find psychically in stores or in any online sellers. The K600 keys are mushy, however, a different kind of mushy. This mushy is muted and very composed, while the K400 felt so out of place. The built quality, although both made of some find of plastic, the heft from the K600 felt like it is quality. The design on the K600 also felt like it was well thought out compared to the K400. Overall, as a budget wireless keyboard that is practically compatible with almost all platforms without any drivers needed is a huge plus for me. Anyone who are looking for a keyboard and wonder if it is compatible with their system, I can safely recommend this keyboard as long as they are only using it for a short while and not long sessions. I find that using this keyboard on long sessions can feel fatiguing and wanting to have that extra key travel that "normal" keyboards do.

I've tried numerous "media Center" style keyboards.... Some with backlight, some without, some with specific freq receiver and some bluetooth. The thing about all those I've tried, the keyboards are tiny rubber keys and a small touchpad. Now to be fair the main reason I've tried so many different ones is because they all fail the same way... the legend comes off the rubber keys, the touchpad becomes so glossy smooth that it simply stops working, the rechargeable batteries die and are not easily replaceable, and in time, they seem to lose connectivity. So what do I like about this Logitech. 1. I've always had great success with Logitech products (Keyboards, Mice, Cameras) so yeah, this was a big part of trying this one to start with 2. This Logitech has a touchpad that's in the region of 2-1/2 times the size of the previous controllers I've tried. I like that. Instead of scrolling fingers numerous times across, this reduces the wear are tear 3. It uses "AA" batteries easily replaceable and not rechargeable that once they die, have to go on charge and you end up with a power lead dangling while you continue to use. 4. It has much larger standard fill sized keys which are also very responsive and tactile. The other remotes I've used with small rubber keys..... you can never type something in without a key missing or kitting the key next to it. 5.The layout is specific designed for Home Theater's/Media Centers. I use this on my Server running Emby and I've had zero problems with any keys. I have one keyboard I have that will not let you terminate an app or browser because you cannot hit Alt/F4.. You can with this one. It has very large separate Volume up/down/mute keys just above the touchpad. Nice touch.... Pause/Run for Emby and VLC also uses the space bar and this is a full size key on this Logitech. 6. One odd feature which I'm also really liking!!!!... It has a separate Yellow Key above the keyboard on the left hand side... It's a Left Mouse Button!!!! Now to be honest, I use the left key all the time and the Touchpad has a very large left and right Mouse Button just below it but that additional yellow one sure is nice to have What could they have done to make it just one tiny bit better... and I'm being picky (but for the price... I cannot complain)... I do wish it had the option to backlight the keys. My Thinkpad Laptop has a keyboard light capability which lights all the keys in between each other. Meaning the keys are not themselves backlit. It's not a show stopper but Most of the keyboards I've bought and tried for Home Theaters/Media Centers have a keyboard that lights up because in the dark it's hard to find the keys. HOWEVER... the main keys I do use are easy located by touch and their size so I've not had any issue so far. The other minor issue is size...this is a 14" x 5-1/2" sized keyboard which is definitely larger than the keyboards I've used before for my media center but is still small enough and lightweight as to be acceptable. Overall The pros of this keyboard for me, totally outweigh the couple of con issues. Only had it a few days but I'd definitely recommend it. I'll update the review in a couple of months of hammering the keyboard and let you know how it has handled itself, battery life etc.

This review is for the Logitech K400 Wireless Touch TV Keyboard. ---------------------------------------------------------------- Update, July 20, 2023 This wireless keyboard still functions like new, but there is one additional quirk discovered since the original review below. Quite often when using the volume controls on the keyboard to raise or lower volume, those two buttons will instead turn off sound entirely. It's a mild nuisance, and only requires pressing the adjacent volume on/off button. Still love this keyboard and use it nearly every day! ---------------------------------------------------------------- October 12, 2021 Wireless keyboards have been around for many years with many brands now available. As far as function, they're all pretty much the same. I've used a few of them over the years and have been happy with this particular device so far. This Logitech K400 Wireless Touch TV Keyboard performs just as you'd expect, with a full-sized standard keyboard layout and a built-in touchpad on the far right. It's perfect for controlling my old laptop that is now connected to my TV. The farthest away I've used it is about 15 feet from the laptop and it has worked flawlessly at that distance. The keys have a nice feel when depressed, providing adequate soft feedback when fully depressed, without clicking. The touchpad is adequate but does have some quirks as described below. The transmitter operates in the 2.4 GHz band, so theoretically could interfere with your wireless network and other wireless devices, although I've used this keyboard extensively and haven't noticed any issues. The Function keys are claimed to be customizable to create shortcuts. I don't have a use for that capability, so haven't tried it and can't comment on how it's implemented. I've only used this wireless keyboard on Windows 10 computers, but the specs say it works on 'Windows 7, 8, 10 or later, Android 5.0 or later, Chrome OS'. The Volume buttons immediately above the touchpad come in very handy. Be aware though, they control system volume and not the volume of individual applications. To control the volume of a single application, use the on-screen controls for that application. The keyboard is a good weight to operate while holding in my hands and seems plenty sturdy for daily use, but not for unnecessary roughhousing - as you might expect. It operates on 2 AA batteries which last a long, long time, taking several months of daily use to deplete. (And that's without turning the power switch off.) USABILITY NOTES: ================= SIGNAL STRENGTH - The signal seems to be very strong, but the keyboard must have a line-of-sight, unobstructed view of the receiver. For instance, when using the keyboard in my lap the signal doesn't reach the receiver if my legs are crossed or my knees elevated so the front of the keyboard can't quite 'see' the receiver. Similarly, I've found that if the keyboard front is facing 90 degrees away from the receiver, the signal is not received. Not big issues, but they may be important to some people. TOUCHPAD QUIRKS - 1. As stated above, the touchpad does have some quirks. On two occasions the touchpad all of a sudden started to ONLY control screen magnification - increasing and decreasing as I dragged one finger across the surface. I've never determined the cause but in one instance, only removing the battery remedied the strange behavior. 2. The touchpad seems to be particularly sensitive to moisture or oil from the skin on my fingers. Meaning, it sometimes simply stops working properly until I thoroughly wipe my fingers with a dry cloth. This is a common issue when using touchpads, but this one is more sensitive than any others I have used, or currently use. MYSTERIOUS YELLOW BUTTON - 1. The yellow button at the upper left of the keyboard is poorly documented and I've seen many posts asking what the heck it does. After more research than expected I found it simply functions as a left mouse button, and I've found it most useful when holding the keyboard in my hands. That way, fingers on the right hand work the touchpad and the left thumb presses the yellow button to select things. After about 5 minutes of practice it seems natural. 2. Some Windows OS menus and windows won't respond to the yellow button. There doesn't seem to be any predictable pattern as to which items will or will-not respond to the yellow button - but when that happens, the left button under the touchpad must be used. FOUR WAYS TO SCROLL A WINDOW - There are four ways to scroll a window; Pick the one that seems most natural to you. 1. Press and hold the Function [FN] button while dragging a finger up/down on the touchpad. 2. Position the arrow pointer over the scroll bar slider; Press the Yellow Button; Drag your finger up/down on the touchpad. 3. Click the mouse pointer on an inactive part of the screen, then use the Up and Down buttons in the lower right part of the keyboard. 3. As with most touchpads, drag two fingers horizontally or vertically. I use this keyboard daily and have been very happy with it. It has a few quirks, but nothing close to a deal breaker. If you need a wireless keyboard, give this one a try. Highly recommended!
