Customer Ratings & Reviews

Perfect budget option for home theater PC. I haven't had any range issue, sitting ~10ft away from PC, but it seems to work ~15ft with no issues either. Battery life is great, I've changed them once since purchasing.

An excellent keyboard/touchpad combo for mobile use. Easy to set up (no additional drivers needed) and great if you're troubleshooting issues in non-standard environments. It's also great if you have a computer connected in your living room. While not as fully functional as a mouse+keyboard combo, the K400 limits the clutter in your living room and is very usable.

Touchpad is a nice touch. Wireless is seamless. Lightweight

I use this for my Raspberry Pi that sits in the family living room. Makes searching things so much easier. Not the mention that it works flawlessly across Windows, Mac, and Linux without any drivers.

Works like it should, was super easy to connect and I use it on our media center pc that is connected to our livingroom tv. Couldn't be happier!!

Now that I've got you humming the Log Song, let's review. This wireless keyboard is my first foray into these kinds of devices, so it is hard to provide an apples to apples comparison. What I have been satisfied with is the quality of the device, which while it is light, it doesn't strike me as chintzy. Of course, it connects easily and quickly, as all these devices do (I suppose). There is very little lag, keystrokes and mouse movements are usually instantaneous. When it does lag it is very slight, almost imperceptible, and it does not happen often. The keyboard is small, and some of the buttons do seem crowded, but I allow for that considering the purpose of the device. I was drawn to it because of the built in touchpad, as I already have enough devices, trinkets, and tchotchkes cluttering up my living room. While I don't have a large frame of reference for these kinds of products, I'd recommend this based on my experience with it.

Got this keyboard to work with an LG Smart TV. It installed and worked right out of the box. Was surprised to find that the YouTube app didn't recognize the keyboard; but the web browser did and I could get my videos that way. One hand operation is easy for interacting while standing. Built-in touch pad really helps.

Purchased this for use on my Media PC for watching Netflix, Hulu and movies. I can have this on my lap and be able to surf or navigate very easliy. It is light, small and responsive. Range seems to be fine as I am about 18 feet from the PC. No lagging, wakes up the PC from sleep mode fine and reasonably priced.

Pretty impressive little keyboard. I like the integrated trackpad for regular tasking.

Excellent Keyboard, the trackpad is great, perfect mobile size, highly recommended

this is a very good little keyboard i use them on our work truck computers

Everything you want in a wireless keyboard for a multimedia setup. Battery life is outstanding and range is never an issue. My only gripe with the keyboard is the lack of a backlight. Aside from that, you’d be hard pressed to find another wireless keyboard with the amount of value and functionality this one has.

Love it. Easy to setup and use. Have had no problems plus long battery life

Last year I picked up the k400r and was happy with it but the shift button is in an awkward place. This K400 plus TV unit does not share that same problem. I also use it when doing maintenance on PCs and need to access a function key for BIOS set up. Additionally, works great with my Android devices too.

Great dual touch-pad / keyboard. I use it as a replacement for my broken Macbook Pro. Very comfortable and easy to use and connect. The only reason for 4 stars is the "Control PC-TO-TV" Button in the top left. I couldn't really get it to work, but to be fair I didn't really investigate the issue. Either way, amazing keyboard

It is small, light and does exactly what it's meant to!

Nice, small, light weight, has nice mouse pad. ....

The Logitech K400 Plus Wireless keyboard takes up little space and functions like a larger keyboard even including a touch pad, so I can keep my laptop high while keyboarding low. Also lightweight for portability allowing use from a distance and easily fitting into a laptop case when on the go.

I love Logitech products. This keyboard looks nice and very light to carry around. It works well with the smart TVs providing convenience for searching movies or browsing internet. The battery life is very good too. I’d recommend it!

Great for the price. I like that they keys have a good amount travel and the built in mousepad make it a nice lightweight and small package for use with Samsung Dex on my S9 Ultra. I just use a USB C to USB A adapter and plug it in.
