Customer Ratings & Reviews

My new Logitech K400 Plus Wireless Keyboard is a great all in one keyboard that's very compact and easy to use and love that it's wireless so I can use it in various ways. I highly recommend it to everyone.

I had to return it because it does not work on YouTube

The Keyboard is very easy to use. Light weight model.

This keyboard is a good size and easy to use. It is similar to the wired keyboard as far as keys and ease of use. The keys are well marked and you can find the various functions easily.

Set up was very easy. I installed it on my Amazon Fire TV. Plug and play. Keyboard keys are just right and mouse area responds very quickly.

I bought this keyboard to be a portable wireless input solution for a variety of situations. I own a computer repair shop and one major use is for laptops that arrive with non-functioning keyboards or touchpad issues. Overall I find that the keyboard and touchpad are quite usable, but there are a couple of big problems. The biggest issue by far is that the F1-F12 keys default to stupid useless media functions that no one ever uses or wants unless you hold Fn when pressing them. This wouldn't be an issue if there was a way to swap their function, say with a Fn combo that inverts the functionality, but the only way to get normal F1-F12 back is to install Logitech's 140MB configuration software on every single computer you plug into! Needless to say, this is a very stupid design choice by Logitech. I frequently make use of key combinations such as Alt-F4 or hit F5 to refresh a page. If I'm on my machine I have the software installed to invert the behavior, but I can't do that on customer computers that I'm trying to repair, the MAIN PURPOSE for me buying this keyboard. If you ever have to hit Alt-Fn-F4 with your left hand, you'll understand immediately why this is insane. The keyboard should be able to remember these feature changes and behave the specified way persistently across computers. As noted by many other reviewers, the arrow keys are compressed to fit in a three-key-wide area. This takes some getting used to but eventually you do adjust to it. I understand why they did this; compact keyboards require some sacrifices. I also find the mushy key travel to be a bit annoying, but again it does not prevent you from typing. I do not understand why there is a left mouse click button in the top left corner; it seems really weird. That would be a good place to put an F-lock button to get back F1-F12 instead ;-) I would only recommend this to someone if a better option was not available. I intend to keep mine but I would probably have bought a different model if I had known that the function keys cannot be changed except by installing a massive software package on every computer you want to use it with.

Pros: Perfect size; Always on no delay; AA battery should last Cons: No dedicated PgUp/PgDn, could be inconvenient at times

Don't throw away the box...the usb is hidden in the box... works perfectly with debian and windows.....the trackpad is also decent

Good range on this keyboard, very responsive from across the living room. Battery life still going after week even after forgetting to turn it off.

Great keyboard small and convenient with mouse good price

This works very good for the price I paid. It works very well with my Samsung Smart tv. Connected very easily.

Perfectly fine keyboard, pretty happy with it. Connection is strong and it works well, but only real drawback is the touchpad isn't as sensitive as a laptop touchpad, so it can be a little more erratic if you want it for something precise, like dragging the scrollbar on a website. All in all, worth buying if you like using the keyboard off the table, like on your lap or something.

We use this all the time with our smart TV. It makes navigating the menu easier

I absolutely love it! It's compact, easy to set up and no trouble at all connecting with my system.

While nothing especially unique, this keyboard is definitely a joy to use in all regards and works without a hitch, and for that alone it is remarkable. I say this because I have used myriad wireless keyboards over the years, and every single one I've had at least one nagging issue that left me less than enthused about it overall even though they were all pretty functional. But with this one, there's literally nothing that stands in the way of it being an all-around pleasurably usable product and an excellent buy. The keys have a perfect amount of travel, the touchpad is just responsive and accurate enough to where you never feel like your fighting with it to do what you want, and the overall spacing of the keys, the size of the keys, and the shortcut functions are all absolutely ideal. To top it off, the build feels very good quality and the thing even looks nice. I purchased this on sale when it was the deal of the day at 19.99 but I have to say that I would have easily paid the $40 regular price and been just as satisfied. Logitech tends to be hit and miss sometimes, but this an excellent all-in-one keyboard/touchpad combo, and the one that deserves your dollars.

Works excellent exactly what I wanted and is a great keyboard

This wireless keyboard is amazing , everything you need , mouse pad and no noise keys are just phenomenal!

USB connection via included adapter, but is wireless. Works well, even has a dedicated sleep button but will not wake the PC. Annoying. Keys work for both Windows and Android, dedicated buttons for the later, fN key for full functionality for the former. (Prt Scr button!) They require some oomph or they won't register all keystrokes. You don't need to jab them, of course, but don't be surprised if it misses a few along the way if you're not consistent. Touchpad is wonky. Buttons are fine, but tapping and scrolling need work. One gentle swipe will move mountains, next touch will need you to grind your fingers to get it to move. Scroll has a mind of its own. Either soft (where it slowly drifts for a bit after you remove your fingers) or hard where one scroll can take you half a page down when you only wanted to read the next line. The software is unobtrusive, free download as well. Easy to install. At MSRP of $39.99, not impressed. Doesn't feel like a $40.00 device. At the current (5/21/17) pricing of $26.99, much easier pill to swallow. At the price I paid, with rewards, it's a no brainer. That said, it definitely has issues that keep it from being worth more than the current price tag and definitely not the $40.00 Logitech wants.

Works as expected No surprises, TV recognized it just fine

This is really great for the price and a lot easier to use than the samsung one I purchased.
