Great keyboard for your TV's micro computer setups! The range is decent and the battery life has been great compared to some other wireless keyboards I've tried.

The reason I bought this keyboard is to use on a server which only needs attention very infrequently so compact size was the most important thing to me. The built in track pad eliminates the need for a separate mouse. The track pad responds well and is easy to use. Setup was super easy, just plug in the dongle and it was working, no setting or configuration needed.

There is not much to say about it. It is simply perfect, plug in and starts working. No hassle.
I got one first and then another one for my children's computer, there is not interference at all and you can get as far from the screen that you can't read it, but the keyboard still works.
It is compact, convenient.. Very recommendable if you are tired of wires and need a simple, efficient keyboard and touchpad.

I use this mostly for working on single-board computers (think Raspberry Pi). It's great to have a small, wireless keyboard that can be easily moved around with the SBC, and the mouse is great if the SBC has a desktop environment installed. It's particularly useful when you're also working with a full-size laptop or desktop computer and you really need the space for other peripherals.
The key arrangement on this one is far superior to the previous version (I think it was the K400 without the plus?). The previous generation had a terrible layout for the arrow keys; this one is more normal. The keys themselves are not particularly tactile, but they're not horribly mushy either. There's a key combo to swap the "Function" keys between F1-F12 and multimedia modes. The touchpad is certainly not as nice as that on, say, a MacBook, but it's not terrible either.
I would not recommend it as a daily driver, but for working with a second computer, or as a keyboard for gaming or working a computer from a couch, it's great. And for the price, it's an incredible value!

Bought this keyboard to be able to use my PC when I hooked it up to the TV in my living room as my office was being renovated. Can sit a good 15 feet away and still type things easily and move the cursor with the trackpad fairly well.

We purchased a new big screen tv and was not even planning on purchasing a keyboard for it until we saw this keyboard. Our teenage son pointed out how nice it would be to have a keyboard for the tv. We purchased this because of the brand, price and size. It has worked out perfect for using the internet and it picks up well across the living room. Fits great in our entertainment center too.

Great keyboard, held back by software

I've had several of these type keyboards, ones made for home theaters, media PCs, etc. I've always liked Logitech's versions with the trackpad. This keyboard is great, feels solid, and doesn't have any physical flaws at all. I like the volume controls above the trackpad and it seems like it would last years on one set of batteries. The reason I didn't give it 5 stars is because of the Logitech software. It removes many functions that the old software for the older model of this keyboard provided. One being trackpad/mouse acceleration. The old keyboard had options for that which made it much easier to get from one side of a 1080p screen to the other with a fast swipe. With the new software, there is no acceleration option. So you have to increase the general mouse speed to get across the screen in one swipe across the trackpad. This makes it hard for fine movements when trying to click small buttons and such. Another thing is that general mouse speed. Cranking the mouse speed in the new Logitech software to the highest setting still does not allow the mouse to get from one side of the screen to the other in one swipe of the trackpad. This is where mouse acceleration would come in handy. So what I have to do is go to the Windows mouse settings and crank the speed up there. With lots of tweaking between the Logitech software and the Windows mouse settings, I've finally got a decent match to get across the screen as well as having some control over clicking small buttons, etc. It's not where I want it to be but it's all I could do. In summary, it's a great great keyboard that is only held back by the software.

Lifesaver! I have my computer hooked up to my TV as well as a monitor, primarily so I can watch movies on it without having to sign on multiple devices and then load up whole other apps anytime I want to switch from Youtube to Netflix or whatever. I've tried lap desks, but they're meant for laptops, not a keyboard and a mouse, and just never felt comfortable in my lap. This has been so helpful! While the trackpad won't win you any games, it's serviceable enough. I find it really annoying to use sometimes, but I also don't like trackpads in general. Though an extra weird thing is the scroll works the opposite of a mouse scroll which can mess me up! But overall, it's been fantastic to use, especially for the price!

Pros: Easy connectivity with windows and a raspberry pi3, lightweight, sturdy feel given budget price, small footprint for easy storage out of sight when not being used
Cons: No scrolling for trackpad that I have figured out yet, kind of frustrating, but at this price ($20) not expected.
Overall: Would certainly buy again for $20 for HTPC or secondary computer (raspberry pi3 - reason I bought it in the first place)

I purchased this use when running my computer to my big screen tv for viewing. It helps me navigate youtube, volume, screen changes, etc. without having to be at my computer (it's a PC). I love it. It's small, easy to use and I love that it has a mousepad. I haven't used it for my small devices, but I would expect it to work well as everything else has been seamless.

Great Keyboard for Fire TV Box

This reviewer received promo considerations or sweepstakes entry for writing a review.
This is a great little keyboard and on-board touch pad mouse to use with the Fire TV Box. The keyboard requires an included USB dongle that is plugged into the back of the Fire TV box. It does not work with the Fire TV stick; since there is no where to plug-in a USB device. The keyboard is not Bluetooth enabled; but the wireless works great.
I had a bit of trouble installing the keyboard until discovered that USB debugging must be turned off. If it is enabled it will make USB accessories unavailable. To turn off USB debugging on the Fire TV box go to Home screen top bar: Settings > Device > Developer options > and turn off USB debugging.{note the warning - enabling will make USB accessories unavailable} After that the dongle and keyboard should be plug and play. The on-board mouse is a wonderful feature; easier to navigate with than with the keyboard arrows alone. The keyboard is comfortable to type with yet is surprisingly very light and compact. Highly recommended.

Very light weight, keys are decent to type with and doesn't lose connection. I Bought this to use with my home theater pc. Works well enough but I feel like it lags a bit sometimes. But for the price I paid I'm willing to live with it. Got it on sale for 15. At that price I think it's definitely worth it.

Great little keyboard, works well with the smart tvs on the market. Also, having the mouse pad on the side of the keyboard help to navigate around. I have mine hooked up to a TV box. Due to the on off switch on the side of the keyboard, it allow the batteries to last a very long time, I have not had to change out batteries yet since I have purchased it it and it receives daily use.

Excellent companion to Android TV

Pros:
This devices integrates pretty nicely with an Android TV (NVidia Shield). This will take up a USB slot on your device to connect keyboard's receiver, so plan accordingly. Once the receiver was connected there were no other steps to setup or active the keyboard. Using from about 6 feet away, the connection between keyboard and device is excellent. The touchpad is usable, maybe a bit less precise compared to recent laptops. There is a Function key giving additional functionality for some buttons. I really appreciated a hard power switch, preventing accidental activations.
Cons:
-1 star for cheap construction: the keyboard is made of cheap-feeling plastic, making suspicious sounds when shaken. The keyboard size is smaller then a regular keyboard. Up and Down keys are half size, following an unfortunate trend from other keyboards, but I catch myself using keyboard mainly for typing, there is still the original remote to move cursor, so this is not a big inconvenience.
The keyboard has no backlight.

Absolutely love this keyboard with built in mouse pad. I use it at work instead of the supplied wireless version. It seems to work on everything I've tried it on including my smartphone when I hookup a usb-c adapter. Even works in bios mode on computers and every tv that has a usb that I've tried. Highly recommended if you need a portable keyboard or you want keyboard capabilitie on your smart tv.

Great little keyboard and touchpad

The keyboard and touchpad combo are just the thing for any use. I use mine for tv, raspberry pi, arduino, and laptop gaming. It is a very portable keyboard and low power consumer for a Bluetooth keyboard. I was able to use the micro USB dongle and pair my Bluetooth enabled laptop with the system at the same time and switch between systems. The dongle easily gets stored in the battery cover and makes it simple to keep with the system at all times. This is a great versatile mini keyboard and touchpad. There is no need to pack a mouse when you have this with you. The touchpad is very responsive and can do pinch push zoom like a laptop trackpad. I bought one for a friend for a steal of $25 at Best Buy around Black Friday and mine for $39 on sale from $49 from Best Buy. Still a great value for this little keyboard.
For the tactile feel of the keyboard, it isn't like a "chicklet" style where there isn't much depression in the key. It feels like you are typing on a full sized keyboard and has great tactile response. The condensed size does take a short bit to get used to, but I have very large hands and I still have great speed and accuracy when typing and for gaming it is also a little bit of a learning curve but still does the trick!

I bought this keyboard to go on my multimedia PC that's connected to my TV in my workshop. It is compact. It has a decent range. And I don't have to fool with a keyboard and a separate mouse. I can also turn the keyboard off when not in use to save my battery. I like this feature a lot. I have a couple of these keyboards actually. I love them

This keyboard is just what I was looking for. It's got a compact size and it's light weight. It was very easy to connect to my TV and now I can navigate my tv's web browser with ease. I wish I could use it to navigate youtube better but that's not an issue with the keyboard. All in all I'm very pleased with this purchase.

I purchased this because my main gaming keyboard was going to be out for RMA and I needed something cheap to get me by. It's decent for the most part. It functions like a laptop keyboard i.e. you have to use the function key to make the secondary actions for certain keys to work like F1 - F12 out of the box or you can download the Logitech Options app from their website to use them as actual Function keys. The app still says 100% battery after a month of everyday use 3 to 4 hours a day. The trackpad is a nice addition for when I'm in bed or far from the desk. I don't need to take an additional wireless mouse with me to control Netflix or Amazon Video functions and it also works well in EUFI BIOS. I'm actually typing this review using this keyboard at the moment. My only real problem with this keyboard is the build quality. It's made out of plastic and feels cheap but for the price I paid I can't really complain much as it was on sale when I bought it. The body flexes pretty easily but it still gets the job done. I actually find myself using it more than I thought I would just so I won't wear out my more expensive gaming keyboard faster. It's Logitech so it works well. I've owned lots of Logitech gear and never had any real issues. If you need a keyboard in a pinch and this is on sale, buy it.
