    • Good for couch potato surfers...almost as good as the old K400!
Style: PLUS Pattern: Floral
I have been using a K400 for almost five years and it has held up well: I dropped it, rolled over on it, and woke up on top of it a few times. After years of polishing the mat texture on the touch pad with my finger, now there is a shiny spot. Aside from that it looks new. But, the left shift key stopped working and the space bar was dead on the right end. Then a few drops of coffee fell between the left and right click and it all went dead. I ordered a new *K400 Plus* and it seems almost as good as the old K400: To be brief, the K400 is black with bold font white lettering on the keys. The *K400 Plus* is grey with a less bold font design that is less visible in dim lighting. For a couch potato keyboard, that is not an improvement. In spite of that, I still recommend it as a fine item. Expect to replace batteries at least twice a year. EXTRA: I used a 6HP wet/dry vac to suck the coffee out and put the keyboard in a plastic bag with $1 worth of rice for ten days. Not only has the old K400 been revived, but apparently the vac sucked some dirt out from under the shift and space keys ....they work like new! ... show more

Review Image by John Posey John Posey
Review Image by John Posey John Posey
So 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. ... show more

    • Good, but it could have been so much better...
Style: PLUS Pattern: Floral
I spend my life tying and working with computers and online. I have used a Gyration air mouse and wireless keyboard for many years. I had the early model that was designed to run Windows Media Player. It worked great and I used it for probably 7 years with no trouble - quality product and I had no complaints whatsoever. That media mouse was much more accurate than the later models, and though I bought the newer ones, they sat on my shelf because of this major flaw. However, recently, the drivers began misbehaving - I suspect because of some hacking issue and I had no option but to retire both and load an old image of my system from scratch - not good. I could not come up with a way to stop it misbehaving, even on an earlier save of the machine. So, I found this little keyboard and bought it hoping it would be OK. So far, so good. I've never had logitech drivers go berserk on me. They seem to do drivers well. This keyboard types well and has good tactile feedback. I use it on an old Belkin laptop desk for stability - it helps a lot. It is a bit small to really use on your lap and it is light enough it would bounce terribly, making typing unreliable at best. But, it is easy to move and seems well made. I have typed for decades and it keeps up with me well. The small keyboard has some shortcomings compared to a full keyboard, but it has some things that they do not have as well. I'm getting used to its peculiarities. I would honestly like a traditional style keyboard on the same scale, but with both touchpad and dedicated number pad, but I haven't seen any. I hate using the numbers at the top of the keyboard - very slow and inefficient for doing any math related tasks. But, it is what it is. The FN key has to be used to access End and Home and Page Up and Down. This is also extremely annoying to me - it will NEVER be as easy as dedicated buttons and the FN key is next to the Windows key which has always been in a stupid place on most keyboards - it is far too easy to accidentally bump it and have unknown chaos erupt and you have no idea what you actually did. Very badly thought out if you intend to actually type with it. That is mostly what I do with a keyboard, but other people, I have no idea. There is no real manual included in the box - 2 very short and basically non-informative pamphlets (one of them disclaimers and warranty legalese) that could have been MUCH more useful.. The main useful thing they mentioned is you can use 2 fingers together to scroll with the touchpad. You have to go to the logitech site to see what it can really do. I can't believe printing is that expensive... Give a person a small key reference for their table for God's sake! I shouldn't have to look up how to use this online at this price point or print out a cheat sheet which does not exist for the more esoteric functions. To you marketing people out there - do not make customers work for anything that should be straightforward. It is bad business practice - period. There is a point at which greed on your part hacks people off. Your product department spent a lot of time developing these things and you don't even tell people why they should like them in the box - really bad business management. You would have failed in my classes. That said, it was pretty much plug and play. It installed flawlessly and has been working fine so far. It doesn't have anything close to 7 years on it yet, though, so I cannot vouch for longevity. I am a designer, so I am very critical of design and execution of products. Much of this keyboard they got right. Some of it could be much, much better. I believe products that are used constantly should be extremely well thought out. So far I have yet to see a really well designed wireless keyboard for serious entertainment/TV/internet/business use. This one does a decent job, but is really not much better than my 7 year old one and in fact worse on some issues. I probably should give it 3 stars for lack of imagination, but it works well for basically what it is designed to do, though there is much room for improvement. I am hoping it becomes less annoying. I hate the FN key keyboards - really a terrible design. Nobody should have to hit 2 keys to get to the end of a line - stupid as hell. People who do not type will not understand this, But if you do - you know exactly what I mean. So, it is lightweight, seems to talk to my computer well, but is very annoying to use for real typing. The touchpad is OK. Could be better or worse. It is average. If you have a widescreen tv hooked to a computer, you will want to go into settings and speed up the mouse - as it leaves the factory you have to swipe, swipe and swipe again to cross the screen. If you have two screens it will be far worse. I do like that it runs on 2 AA batteries. They hold a charge well and for a long time. I only use rechargeables in electronics and the trend to AAA is pointless on something like this and it only takes up two slots in my charger instead of 4. Good decision on the designer's part. Until I can find a better one, this will do. But, if you people at logitech are reading this - seriously? Think about how it will be used! Then design it, not the other way around. And ask somebody who actually types and uses the internet/TV functions to use it before you make it a production model. The world is waiting for a superb multipurpose keyboard and NOBODY makes one. There is profit waiting for the company that does. If I could, I would, but I don't know a manufacturer who would listen to me, sadly. If you are looking for a keyboard that works and is pretty good, this is such a device. I can recommend it as no worse than others I have used, but it is not close to what I really want.
