Logitech Wireless Touch Keyboard K400 Plus - Black Replaces K400R Black

It is 100% multimedia keyboard and was made manly for this purpose only. I bought it around 2 years ago from "PB Tech" to watch my movie from my desktop PC on a big TV screen via HDMI cable and it works very good as you will expect from "Logitech". Great value for money too and very functional for such a compact size keyboard. But because of the price it made of a cheap hard plastic and not made for long typing but for a search and navigation only. It is Mousepad and Keyboard in one devise and has a great range up to 10 meters from USB (not Bluetooth) but has no backlight to see in the dark. But because my TV is big and bright it does not matter for me. I 100% recommend it for watching movies and have no regrets so far and batteries in the keyboard last over half a ... MoreIt is 100% multimedia keyboard and was made manly for this purpose only.

Fine for light use

It is convenient and gets the job done. Best suited for the couch on a media PC, or other light occasional use. Bought this to replace an older K400 which did not stand up to the test of time. This is the K400 Plus, but I'm not sure what's "plus" about it. It's the same thing minus a few keys. I'm literally re-buying a cheap keyboard, did they think I wouldn't notice? Would have been nice if they added Bluetooth support or something like that, but nope.Quality wise, the base is flimsy and feels cheap. The keys feel like they would probably break if popped off. The batteries rattle in the compartment. For the price it's alright I guess, but I feel like this is on the lower end of Logi's cheaper products.The key layout is cramped and it's not good for performing ... MoreIt is convenient and gets the job done.

For the price it's alright I guess, but I feel like this is on the lower end of Logi's cheaper products.The key layout is cramped and it's not good for performing complex keystrokes. Compared to the older version of the K400, they got rid of the top row of buttons, as well as the print screen and scroll lock keys which were accessible with the function key. If you need those keys you have to install the Logi Options software and reassign one of the other functions.

It's compact, but has lots of software issues

The keyboard itself is fine for what it is. Wireless works fine and the size is good for the living room. The software kills this thing however. To configure it, you need a nearly 400 MB application that does nearly nothing, but if you want to switch the function keys to actually be function keys, you need to run that software. That software often crashes, meaning the volume controls and function keys will stop working until I restart the bloated software. Super annoying if you're watching a movie or something. Also, the trackpad is barely usable. It's not very accurate and it has no multi touch gesture support aside from two finger scrolling. It would be so much more useful if you could do three- or four-finger gestures. I would not buy this keyboard again and wish ... MoreThe keyboard itself is fine for what it is.

Logitech remains reliable and convenient and affordable

I got this keyboard since my office sometimes gets too hot and I have to work downstairs with the extra monitor. this keyboard, like other Logitech products, is easy to set up. It's responsive and portable, something I will take with me when traveling for conferences and work. The mouse takes some getting used to. The compact size is great, but I am used to tying on a full keyboard so the mouse is often oddly close and my hand has to move twice since I expect to drag it out farther. The minor complaint I have is that the dongle needed to connect the keyboard to the laptop has no place to house it. So if you want to travel with it, you have to figure some way to keep the dongle close to the keyboard so you don't lose it forget it. Otherwise a great product

Mac User's Perspective

I got this keyboard to use with my macbook that's connected to my home theater. I couldn't find many reviews of the touchpad compatibility with macOS so here's my experience.The touchpad can be used to track and scroll with two fingers on Mac. You can also lightly tap on the touchpad itself and it'll register as a click, and double tap will register as a click-and-drag. The tracking is not as good as the glass trackpads on the macs but it's good enough with a little sensitivity increase in settings. Gestures like three-finger swipe won't work but it's not really that big of a deal since you can replicate most of those with keyboard shortcuts like ctrl+left/right. I wish it was a little bigger though.Other than that, the keys are totally fine and the volume ... MoreI got this keyboard to use with my macbook that's connected to my home theater.

I wish it was a little bigger though.Other than that, the keys are totally fine and the volume buttons and function keys work as expected. The yellow button on the top functions as a left click button which I found to be really useful when using the keyboard two-handed since you can't physically push down the trackpad to register the click like on a MacBook.It's a pretty solid keyboard/touchpad combo for the price and works perfectly fine for a TV or home theater setup from a long range. I really wish there were more options for this type of product since most of them are separate keyboard and mice and there's hardly any external touchpads on the market.

Minimal adjustments

I've had several of these keyboards which I use for PC-TV control. Overall, they work quite well, soft keys, good feel, battery life is good as long as you remember to turn it off when not in use. I've been using these now for about 4 or 5 years? I've already had one 'die' on me with some of the keys typing random characters. For example press the 'Q' and get 'qp' or 'S' and get 'sy'.The Logitech options software gives you some control over the touchpad, but not as much as you might have with Synaptics software on your laptop. And not as much as you really need. Touchpad sensitivity is not adjustable that I can find. When trying to scroll the keyboard may zoom the screen no matter how much effort you put into making sure you don't spread or pinch. This is possibly ... MoreI've had several of these keyboards which I use for PC-TV control.

This is possibly the biggest complaint I have with this keyboard.Having tried multiple wireless keyboard/mouse options, this with it's size and features is possibly one of the best. Definitely a step up from the K400 (not plus) which I originally had, and have put on the shelf.There are definitely more featured keyboards out there, at higher prices, however for use on a PC/TV setup, I haven't been able to find anything better.If Logitech can fix the touchpad software, they would have an excellent product.

Requires software to activate Fn lock

Logitech K400 plus is an excellent keyboard for light uses. However it came with major inconvenience.First of all, I quickly found out there is no Fn lock built in. The only way to activate Fn lock is through Logitech Options software, which is a 297MB download. It's a software solution, so software is required to be running at all times.Second, the touchpad is oversensitive and mouse will drift a little after my finger stops moving. The left/right mouse button is not sensitive, making clicking button and drag from touchpad a pain to accomplish.At $30, I think the value is acceptable. But I won't recommend this product. I'm keeping the keyboard only because I have a strict size limit for my setup.

Stands the test of time and wear!

I will start off by saying I bought my current K400 elsewhere at least 10 years ago. Its been in service that whole time. It's what I am using to type this review with a Mac M1 Mini.I do not review much, but when a product works well or is really bad, I will submit a review.I have dropped this keyboard many times, and because of that sometimes the batteries fall out - just stick em back in, close the cover and it pairs up again in seconds...on its own. Also the batteries last a very long time.The bluetooth feature works well, the connectivity even goes thru ceilings and walls. The touchpad is sensitive and responsive.The only con I have is one of the little rubber feet, on the bottom, fell off so on a flat surface it rocks a little - I could have glued it ... MoreI will start off by saying I bought my current K400 elsewhere at least 10 years ago.

That is almost a moot point because I usually use it sitting on my lap.I am buying a new one from B&H, not because this one is broken, but because I am retired and I will have a backup that should last the rest of my lifetime. Well worth the under 30 bucks w/free shipping they are charging!

Works with Steam Deck

I recently purchased a Steam Deck and needed an easy way to type and click on items when using the Steam Deck in desktop mode as it's track pads take some getting used to. I originally thought of getting a separate wireless mouse and keyboard combo but decided to save some space and get this in stead.Just plug in the reciever into your dock used for your Steam Deck, pull the plastic on the batteries, flip the switch to on and off you go. No drivers needed it works right out of the box.It is a little longer than the Steam Deck and slightly wider as you can see in the photos. This allows you to save a little room on your bag since you don't need to have a mouse and it reduces the weight a little as well. Over all this is a good investment for those looking for a ... MoreI recently purchased a Steam Deck and needed an easy way to type and click on items when using the Steam Deck in desktop mode as it's track pads take some getting used to.

Worst touchpad ever

I'm using it with a WIN10 PC, which is on my TV.+ All the features they write about in the product description.+ It is well built.- Worst touchpad experience ever. I used a bunch of terrible touchpads in my years, and this is worst than any budget laptop's touchpad.- At max pointer speed (maxing out in Logitech Options, without adjusting Windows settings) 1 slow swipe from left to right moves the cursor only to the middle of the screen or less, which is miserable. It moves less and less as I move my finger faster, to the point that the cursor doesn't move at all, or even moves backwards if I don't pay attention and swipe casually as I'd usually do. I could adjust the main setting in Windows, but that makes my old M180 mouse too sensitive to use.

(I chose K400+ partly because my mouse needed a new unifying receiver)- Factory settings are inverted for scrolling and FN keys, and you have to KEEP a 340 MB software on your PC to keep the settings normal.- You need Logitech Options Software (340 MB) to change the inverted factory settings and YOU CAN'T DELETE IT after everything is set, because you lose the settings. Other than these, the Logitech Options software is a useless. [And wouldn't even be necessary if the factory settings were right. Logitech Options Software's other "features" are disabling functions you don't want to disable (like pinch-zoom and two-finger scrolling), and adding some limited functions to some of the FN keys. It can also change the pointer speed from terrible to even worse.]- You CANNOT change scrolling speed (which is way too fast), touch sensitivity or accidental touch protection.- It does NOT HAVE edge motion, edge scrolling, 3 and 4 finger touches and gestures (actual features, that I have in my 2018 budget laptop, with a 40 MB software.)- The left mouse button in the upper left corner is utterly useless.
