      Overall decent but with some big annoying problems

      • My Best Buy® Elite Plus MemberElite Plus Member

      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.

      Great Keyboard but Cheap Material/Design

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      The keyboard works great. It works instantly out of the box with the IR USB dongle and flipping the on switch on the keyboard. I like that the battery compartment has an area that this little dongle can be stored so it doesn't get separated from the keyboard when not in use. The connection between the dongle and keyboard are very good. I have 2 of these keyboards, one at home for a home theater arrangement where the keyboard is mostly in sight of the device of which the USB dongle is attached. No real interference there. The other keyboard is in a corporate environment where the computer (Mac Mini) with USB dongle is behind a aluminium beam thick wall! The keyboard picks right up and only SLIGHT hesitation on first trackpad use but after that works perfect! I originally had an Apple Magic Mouse & Keyboard (newest version) paired to the Mac Mini but the connection to these Apple devices failed horribly going through the wall. At times wouldn't connect at all! This Logitech wireless keyboard and trackpad worked great with no concern for problematic issues later down the line. The only real con for this device I would say is how cheap it feels and looks. If the technology from this product was paired up with the design team from Apple, it would be a perfect device! Instead you have a cheap plastic, so so design and the light feeling of a china made kids toy. I'm sure if it was put to the test on durability it wouldn't last long. Thankfully for me, I take care of my technology and this works great for my needs! I do know that logitech does make higher model versions of this same type of combination but those are TOO large or "PC" looking. I was draw to this item because of how simple it looked and operated.

      Don't Waste Your MOney!


      Pros: wireless compact built in touchpad quiet typing Cons: a little TOO compact feels cheap keys in awkward spots no instruction manual to tell you what some of the keys are for registers taps on touchpad even if you didn't tap it if you type fast it responds slow price: $32.12 incl tax at best buy My Thoughts: I really wanted to like this keyboard as i was dealing with pain in my wrist and was told not to use my pc mouse as the lateral movements would irritate my wrist so i was limiting my pc time a huge amount. then i saw this keyboard on best buys site and on amazon.. the reviews seemed promising. so i purchased the keyboard at best buy on October 3rd. the keyboard was easy to set up-- just plug in and play-- so drivers needed so after putting away my regular keyboard and mouse, and plugged the dongle for the k400+ into my usb port and set about to use it to get the feel of it. i still limited my PC time and slowly got the hang of it.. although it did take me the better part of 4 days to figure out how to do a print screen command with it-- finally had to look it up online. everything seemed do be going smoothly, but i hated the placement of the caps lock button and the fact that f i typed at my normal pace they keyboard was slow to respond. not too mention the overly compact size made it hard to get a good typing position as everything seemed squished together, the touchpad took some getting used to and even then would register taps on it when i hadn't tapped anything and would open links if i scrolled over them while reading-- it was very annoying. On October 10th as i checked my email the mouse pointer abruptly froze on my screen! i tried everything!! i replaced the batteries(even though the batteries were brand new) i put the dongle in a new USB port to see if it was a port problem, i even restarted my PC, and the pointer remained frozen!! the touchpad wasn't registering, so in a panic i grabbed my old mouse and plugged the dongle into the original port-- and it worked perfectly! i rapidly came to the conclusion that after a week of use(and limited at that cause of my wrist) the touchpad on the keyboard was DEAD!!! I returned the keyboard to best buy on the 11th and was able to get a full refund-- they even asked if i wished to exchange it and try another one-- i declined... i didn't want to go through that headache again,

      Simply THEE best purchase I've made


      This keyboard incorporates tons of shortcuts that I use on my computer every single day. Not only does it have extensive media controls, but it also has window shortcuts I use such as ALT + TAB that can now be done with F3 function button. I'm not going to lie, I don't like trackpads on laptops. This trackpad seems smoother, and less studdery. The most useful feature in combination with the pad however is the little yellow button on the top left corner. This allows you to mouse left-click with your left hand while you use the trackpad with your right hand. This is an incredibly innovative feature. On top of all of this, this keyboard is small enough and compact to allow me to keep my hands in place while still being able to reach any button on the keyboard (Not including the volume controls that are offset with the trackpad). You might be thinking, "Oh, well I have fat fingers so I can't use this. I need something bigger." Not true in the slightest. On top of being small and compact, the letter and number keys are normal size. The only small keys are the function keys. So, while typing, it almost seems as though you're using a normal laptop keyboard. The ONLY people I suggest stay away from this product are people that simply cannot use laptop keyboards. There is no depth to the keys, so it legitimately feels like you're typing on a laptop. I really hope this review helps you decide what you are going to purchase. Shout out to Logitech for putting an incredibly functional and ergonomically product out there on the market.

      Excellent little keyboard

      • My Best Buy® MemberMember

      I love this little keyboard. It is compact and lightweight and functions perfectly! I bought this keyboard to use in my workshop. I wanted a simple, all in one compact keyboard. I didn't want to worry about loosing the mouse or cords of any kind. This item fits the bill. First off, it's a Logitech. IMHO Logitech is the 'go to' as far as mice, keyboards and remotes. I own quite a few and have had zero problems. Secondly, this keyboard is small, but still quite functional as far as typing. The touch pad (I'm usually not a fan of them) works perfectly. I hooked the keyboard up to a PC running Windows 10. It was immediately recognized and started working. So no compatibility issues whatsoever. Another thing I liked is the keyboard doesn't have those little plastic feet that flip down. They always seem to get broken off. The keyboard has rubber feet and is thick enough to allow the perfect typing height. I can't say enough good things about this keyboard. I really like it. I think I will pick up another for my security camera server. The on/off switch allows me to turn off the keyboard so I don't waste batteries. (OH btw, batteries are included too!) The only thing I don't like about this keyboard is the packaging. BE careful!!!! The keyboard USB dongle is very small and tucked into the lip of the packaging. Very easy to over look and throw away after unboxing.

      Weird Range Trick I Found....


      I got double the range with a weird trick. Instead of plugging the dongle directly into the back of my pc case, I plugged it into a usb hub. I'm guessing that getting the dongle away from the computer helped with interference, maybe? Or maybe I just got it in a better line of site to my TV. Whatever it is, I thought I'd share. When I had the dongle directly in my case I got maybe a 10 foot range. Now I'm sitting 25 feet away and it is working perfectly, granted it is a straight shot with no walls interfering Your mileage may vary. But anyway, for the money, I do like this keyboard a lot. I use it for doing homework with my TV as a second monitor (and my butt enjoying my couch). It's a little on the cramped side, but it's a pretty similar experience to most compact laptop keyboards, which is what I'd have to be using with out this option. Also, FYI, I'm running Ubuntu and it's working without any issues.

      Excellent keyboard, good improvements on the K400


      I've owned two of the original K400 keyboards. The first one had the touch-pad die after 2 years, the second didn't survive a short drop onto a carpeted floor. Hopefully, this new model has a bit better quality control. The Plus appears almost identical to the original K400. The volume keys are easier to reach above the touchpad, the mouse buttons are a bit smaller and more difficult to use. The keys have more travel, better feedback and feel more like a regular keyboard. The keyboard layout is excellent for a media keyboard. The alphabet keys are full sized, and touch typing is easy. Many of the minor keys (Ctrl, Alt, etc) are half sized. The Plus has a slightly better layout than the original, with full sized Shift and Enter keys. The touch-pad is an excellent multi-touch that supports two-finger scrolling, panning and tap-to-left-click (assuming your OS has these features, of course). The keyboard is Android friendly if you have a USB adapter on your Android (however, not all versions of Android have the K400 driver). The volume Up and Mute keys work in Mint Linux, but not the volume Down key.

      Great wireless keyboard

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      This is my 3rd Logitech K400 plus And works flawlessly. The reason for being the 3rd is my first after a couple years and dozens of drops on marble floors was finally time to replace. The second was bought for a family member who loved mine and now uses hers exclusively instead of her laptop keyboard. The third one was to replace my first one. The keys are smooth the touchpad responsive with no noticeable lag time. Both my sister and I use ours for controlling laptops projected to a second screen. It works from anywhere in the room (mine is 20'x20') and allows us to keep the laptop closed, preventing dust and dirt from our fingers from gumming up or prematurely wearing out our laptops. Battery life is great! I might have to replace the 2 AA once or twice a year and I don't turn off the keyboard so I would expect the batteries to last much longer if you push the off button when you are not using it. 1 drawback is not having a backlit keyboard but for the amount I use it in the dark and the battery life I receive I find that to be a very acceptable trade off, plus with the built in touch pad and location of the main keys it's still easy enough to operate in the dark by memory. I wouldn't want to type a letter in the dark with it but I'm not a typist and the long battery life and longevity and ability to take so many drops from the bed or couch onto a hard floor before succumbing (still worked it just had some sticking keys) make the Logitech 400 plus a very easy to highly recommend product. Oh another plus is the programmable USB dongle so you can control other Logitech devices if you care too. A+++
