John PoseyReviewed in the United States on December 17, 20225.0 out of 5 stars Logitech once again delivers a fantastic product!
Style: PLUSPattern: FloralVerified PurchaseSo I’ve had my Xbox Series X since it launched November 2020, and have been considering purchasing a wireless keyboard to solely use with it. Here recently more and more developers are including native keyboard and mouse support in their games, so the benefit of having a keyboard to use is growing. Since I did not plan to actually “play” the games with the keyboard, but instead use it for “QOL” enhancements, I didn’t want to spend a substantial amount of money on a wireless keyboard. After doing some research on gaming forums, and multiple Reddit /Subreddits, I continually kept seeing a specific Brand/Model of keyboard a lot of posters were suggesting. The keyboard being suggested was the “Logitech K400 Plus”, so I decided to pull the trigger and give it a shot…. I’m glad I did.
The Keyboard arrived my house and I instantly noticed how insanely light weight it was. It’s weight was what shocked me initially, but the bigger shock was how well built and durable it felt, especially considering it’s budget friendly price point. So I removed the included USB-A dongle, and inserted it into my 4-port USB 3.0 hub plugged into my Xbox Series X. I flipped the keyboard switch to “ON” and it instantly connected to my Series X and was flawlessly responsive, and had no sign of lag whatsoever. What I didn’t pay much attention to when I researched and decided to purchase the “K400 Plus” was the functionality it possesses pertaining to “Multimedia”. Logitech designed this keyboard to be the perfect “couch” companion for use with smart tv’s, especially tv’s with native web browser applications. So this keyboard became that much better of an addition to my Series X. All of the playback multimedia buttons work perfectly with my Series X, and since Microsoft manufactures the Xbox systems and this keyboard is geared towards “Windows” based computing, the two handshake together in perfect harmony.
Another neat features of this keyboard is the “Left Click (Mouse)” button that is situated in the very top right corner of the keyboard. When I first looked at the Left Click button location I was somewhat confused as to why it would be beneficial in that location. It didn’t take long for me to realize it’s genius though, and I can confirm that it is brilliantly placed in the perfect location. I launched the “Microsoft Edge” browser on my Series X, and instantly realized how perfect it was while scrolling the webpages with my right hand on the touchpad, and being able to use the button to click everything I needed to seamlessly. All in all I love this wireless keyboard, and IMO it’s the hands down best budget wireless keyboard on the market. I’ve attached some photos (they didn’t turn out that great due to room darkness) that will hopefully give you an idea of its size.
- PROS:
• It’s size is perfect for sitting in your lap, and honestly it’s so light you will forget it is even there.
• Logitech designed this keyboard for media consumption, so it excels in it’s functionality with media.
• Even though it’s price is very budget friendly, you will be surprised by just how well built it feels.
• Button clicks feel very tactile and solid, and IMO have the perfect “Spacing” for ease of use.
• It’s manufactured by Logitech, and Logitech has world class customer service if something doesn’t function correctly after your keyboard purchase.
• All in all a rock solid wireless keyboard that is rich in features without breaking the bank.
- CONS:
• In all reality I honestly can’t list anything that I feel is a con, but I will list some things that potentially could of placed multiple cherries on top.
• This keyboard used AA batteries (2) for it power source, and I imagine some people would of preferred a rechargeable Li-Po battery, but quite frankly I could care less. I personally like being able to simply change batteries when it dies and instantly go back to using it, versus being unable to use it while it has to charge, but to each his own.
• If this keyboard had backlit keys it would be pretty awesome, but I wouldn’t expect it to considering it’s price point. Nonetheless it would enhance it’s appeal that much more.
• It would be nice to have bluetooth functionality but at this price point it would be shocking if Logitech had designed it with bluetooth support. In my individual case, the Xbox Series X can only use keyboards via USB-A connection (Wired or Wireless w/ Dongle), so bluetooth wouldn’t benefit my application at all but having the ability to use it with other devices would never hurt.

Ace KnightReviewed in the United States on March 13, 20245.0 out of 5 stars Oops. Did Not Realize It NEEDED The USB Dongle
Style: PLUSPattern: FloralVerified PurchaseI already owned a small bluetooth keyboard I had bought for use with my Kindle tablets. I have a few 10in tablets that I sometimes use to connect remotely to my main desktop PC. The setup works incredibly well when you pair the tablets with a wireless keyboard and mouse.
I bought this additional bluetooth keyboard because there are times I'd like a keyboard, but don't want to have to deal with a separate mouse. Plus there are other times where I need to access a headless PC, or my Raspberry PI, or where I'd love a wireless keyboard for playing Steam games, etc. So I was looking at this keyboard as being great for multi-use.
The one thing I hadn't realized was that the small USB dongle (which is in the front flap of the box) is REQUIRED. Since the product description said this keyboard worked with Android, I just assumed it was like my other bluetooth keyboard and didn't need anything additional to plug in. As it turns out, yes, you DO need to use the usb dongle with a tablet or your phone -- and that kinda sucks because obviously those devices don't have a USB-A port.
Luckily I had a USB-A to USB-C converter from something else I bought and I tried it out in the Kindle Fire HD10. The keyboard and touchpad worked immediately! Yay!
I've ordered a right-angle USB-A to USB-C adapter, so that it's less likely to break if I bump it into something versus the straight USB-A to USB-C adapter that I have now. Then I'll be in-business, regardless if I want to use this keyboard with my tablet, a home theater PC, phone or whatever.
The quality seems decent. I haven't had a chance to fully test it out just yet, but if I have any issues I'll update the review.
The only other slight gripe is that there's a power switch, so it looks like it has to be powered on or off with the switch versus automatically powering off like my other compact bluetooth keyboard. I tend to forget to shut things off that I normally wouldn't have to (like a wireless mouse). I'd hope that the battery wouldn't drain when the keyboard is not in-use, or it would at least be minimal drain -- but time will tell! It's nice that it uses AA batteries so they're easily replaced.
All in all, this keyboard looks like it'll work out well for being a multi-purpose keyboard. It lacks the convenience of a dongle-less keyboard, but having the touch pad built into it makes it VERY convenient when you don't want to have to operate a separate mouse. There have been many times I've worked with a headless PC in the last few years and it's annoying to try to navigate with just the keyboard, or have to setup a mouse on the floor. So this keyboard will solve that problem. And, I'm actually looking forward to trying it out with Steam games to see how it holds up with some games being played while on the couch.

ReportTranslate review to English 
R EReviewed in India on November 7, 20165.0 out of 5 stars Excellent product. Lightweight and small, without compromising too much on key size.
Style: PLUSPattern: FloralVerified PurchaseJust had it delivered a few hours ago. Tried it with my mobile (had to get a small OTG adaptor to get started). I also own the K480, and got this one because it has a touchpad. Comparing the two, both have unique features that I would not call positive or negative, because how one views a feature, or the lack thereof, depends on one's requirements. The plus-point of the K480 is that it connects through bluetooth, leaving the port free to charge the mobile (if you want to use it with your mobile/tab) or connect a pendrive to it. The keys are larger and better spaced out (important if typing comfort is a major priority). The K400 plus, on the other hand, requires the OTG adaptor, plus, the unifying receiver used to connect the keyboard to devices like the mobile, tab, or the LCD TV. The plus point of this feature is that connection is immediate. The minus point is that one must be careful not to lose the 'unifying receiver'. Also, if you forget the OTG connector, there is no way you can connect the keyboard to anything. The 'K400 Plus' is also lighter and slightly tinier: But comfortable enough for normal to large sized fingers to type without any obstacles. Unlike the K480, this piece has the touch pad. One main advantage of going for these keyboards ( be it the K480 and K400) is the amount of money saved...in my case, I saved 28K approx., the amount I would have to invest for getting a new laptop. And just didn't have the money to invest in one. Now, with this, I can complete most college assigments. And a couple of years later when my phone conks off, I can simply get a new smartphone for about 8-10K. If one calculates the interest accumulated, one has way more in one's hand than one thinks.

Ryan BReviewed in Australia on November 30, 20255.0 out of 5 stars Good keyboard but a bit overpriced.
Style: PLUSPattern: FloralVerified PurchaseVery useful keyboard for a media centre PC. Very handy having both the keyboard and trackpad in one unit rather than trying to find a surface to use a mouse on. Keyboard is good to type on. The unit as a whole feels solid but the plastic it is made out of seem quite cheap - which the product definitely was not! So the prices Logitech charge are a bit high but its the only media centre keyboard on the market so you just have to deal with it.
Report
T. SimReviewed in Singapore on April 17, 20235.0 out of 5 stars The dongle is on the flap of the box.
Style: PLUSPattern: FloralVerified PurchaseVery important detail. You would expect the dongle to be in the battery compartment, but it is actually on a flap on the box. Seller was very polite and helpful when I enquired about it. On an unrelated note, this keyboard works with the Logitech Options software, but Logitech Options, the program to configure the keyboard does not seem to work with Window 11. Just something to be aware of. The keyboard and trackpad will still work, only there won't be a way to reverse two finger scrolling direction. That is a Logitech issue.

sPuTnikReviewed in Canada on July 13, 20225.0 out of 5 stars Excellent Compact Wireless Keyboard with Integrated Mouse Pad.
Style: PLUSPattern: FloralVerified PurchaseThis review evaluates the “K400 Plus Wireless Touch TV Keyboard” made by LOGITECH.
The product was shipped with no excessive or wasteful packaging and all components were contained snugly in the box. What’s in the box: one (1) Wireless Touch TV keyboard, one (1) Logi “Thunderbolt” wireless USB-A transmitter, two (2) AA alkaline batteries, and user instructions. This keyboard took almost a month to be shipped to me however; it was well worth the wait.
First impressions: Solid, compact, and lightweight. This keyboard is well made and nicely laid out with an integrated mouse touchpad on your right-hand side. It has minimal flex and a nice rigid feel. The keyboard connects to your PC via a USB-A transmitter key. It is powered by two (2) AA alkaline batteries (provided) which can last for up to 18 months of use (based on 2 hours per day). There is an ON/OFF switch on the front of the keyboard to preserve battery life when not in use.
Keyboards are a very “personal” piece of sensory input equipment; you will never please everyone with how the keys “feel” and perform in the hands of the operator. This keyboard has a nice soft yet responsive input and is comfortable to type on. The integrated mouse pad feels identical to that of a laptop. The keyboard has decent range, I tested it at multiple distances up to 15 feet with no loss of connection.
Cost-effectiveness and value: Overall I am very impressed with the product, it is well made, compact, and does a good job. I was looking for a compact keyboard with an integrated mouse pad that utilized a small footprint on my shop workbench… This fits the bill to a tee. At a current price of $39.99, I feel it is fairly priced for the functionality and convenience delivered.
In summary: the “K400 Plus Wireless Touch TV Keyboard” made by LOGITECH is well made, compact, and does the job it should. I would recommend this product without reservation.
Pros ????:
✔ Well-made using quality materials.
✔ Solid, compact, and lightweight.
✔ Nice responsive soft-touch keys.
✔ Integrated mouse pad.
✔ Wireless connectivity via RF USB-A transmitter key.
✔ Good connectivity distance – up to 33 feet.
✔ Long battery life – up to 18 months based on 2 hours use per day.
✔ Fairly priced and good value.
Cons????:
✘ None!
