Logitech K400 Plus Touchpad Wireless Keyboard Black - USB Wireless Connectivity - On/Off Power Switch - 2.40 GHz Operating Frequency

Very cheaply made product. Keys are terrible to type on and have a stickyness to the action. Trackpad works ok but not happy. Not rechargeble via aa battery requirement. No backlight… returned.

I've owned at least 3 or 4 of these keyboard/trackpad combos over the last ten or fifteen years and it gets the job done but I wish it had a better 'feel' especially the trackpad which works but doesn't hold a candle to something like the trackpads you find on most modern laptops

It does what it says on the tin, it's just a shame that Logi hasn't updated or iterated on this concept in years. Sitting next to the MX wireless keyboards it feels like a cheap toy, and since the AAA batteries will need to be replaced eventually, it's a big downgrade. But it's the only real option available for a keyboard/touchpad combo, so what choice did I have?

Pros: lets me control my PC from the couch and has a useful mouse button at the top left corner, for holding the keyboard like a big gamepad. Cons: keys are really squishy, no backlight, trackpad gesture controls don’t work in all windows apps, two-finger scrolling jumps multiple lines when starting to scroll (this is the intended behavior from this device), uses disposable batteries, feels incredibly cheap. This fit my requirement for a combination keyboard and touchpad, but it is not pleasant to use. If Logitech made an MX (high quality) keyboard with this form factor and a trackpoint under the touchpad, I would buy one in a heartbeat.

It's an okay, inexpensive keyboard that I'm using for a media computer hooked up to my TV. It does the job, but it is extremely flimsy feeling. I had a similar logitech wireless keyboard probably 15 years ago that had a much more sturdy feel, and I was hoping it would be the same but it's not nearly as good. The trackpad tracks well, that's definitely worth mentioning. It's a solid 3 stars; it gets the job done but it's nothing exceptional.

[This review was collected as part of a promotion.] We love it except for the power switch…. It could be better than it is But we definitely would buy it again 👍

[This review was collected as part of a promotion.] I've been wanting to get this for a while to be able to more easily control my Chromecast and enter text more easily. I like the colors and the mouse control with the top left click button on the keyboard, really smart! My gripes are: 1) It's a bit larger than i imagined. It's still very close to a full size keyboard, and I would have expected it to be smaller and less obtrusive to my living room. 2) Connections: In order to connect to a chromecast I need an additional adaptor, which is chromecast's fault, but then a USB-C dongle would have been nice and smaller. Somehow all old USB connectors just feel obsolete at this point. Ideally this would actually have bluetooth, so I could just connect it wirelessly directly to the device with no adaptor or dongle at all. 3) Maybe Logitech are still treating this as a computer device, but I have a feeling 80% of the people who get this, get this to control their TVs or media stations. Why not just acknowledge that and make it a keyboard/remote hybrid? add dedicated buttons for top apps like youtube or netflix, add an arrow keypad to navigate left/right/up/down? Get with the times.

[This review was collected as part of a promotion.] I have a computer hooked up to my home theatre system I wanted a small keyboard and mouse to be able to sit away and have a remote like experience. This so a great addition. Sold connection and a built in track pad so no losing one component. Compact enough to set on an end table or keep away from the kids. Just a great product. Wish I could have found something a bit smaller, but this does the trick all the same.

[This review was collected as part of a promotion.] Bought this to supplement another keyboard for my HTPC. Gets the job done but I wish it had background lighting for the keys.

[This review was collected as part of a promotion.] Touchpad adds comfort giving freedom from conventional mouse. Light and easy to carry.

[This review was collected as part of a promotion.] I could not use with my new computer hp series . It would not hook up with its blue tooth wireless setting...tried many times ,very un-happy . Can you help with this problem ?

Perfect simple keyboard with excellent battery life that get things done!

Great all around media keyboard. Adjust scrolling speed and ready to use with your fingers.

I like the fact that it has a trackpad built into it, the scrolling with the trackpad takes a bit of time to get used to but it’s not too difficult on my fingers . I haven’t used the keyboard for a while but battery life is good so far.

This keyboard is extremely useful for testing/building different PCs. So convenient compared to dragging around individual mice and keyboards. Pretty much any PCs that aren't in a long-term desk situation, this is a must have. They are fantastic for media center pc's. It is wife tested and approved . The keyboard has survived many drops from a height of as much as 5 feet onto to a hard wood floor . For the price, it is one of the best wireless keyboards I have found ..Just buy it .

Overall, this keyboard is more than adequate, especially for the price. General build quality is great. The keys have a good weight and feel, and I'm able to type as fast and accurately on this keyboard as I am on keyboards that cost double or triple this. The trackpad also has a good feel, and the physical left- and right-click buttons provide confidence in what you're doing, especially in darker scenarios. My only gripe is how it handles two-finger scrolling. Out of the box, scrolling is not inverted, while inverted scrolling is my preference. After finding that there were no tuning options in Windows, I had to download the companion Logitech app, which gave me inverted scrolling, but it broke the scrolling speed. Prior to the app installation, scrolling speed was exactly what I expected, but after tweaking those settings, swipe scrolling is now unusable, as it is incredibly fast. Attempting to move down a couple lines of text results in jumping to the bottom of the page, with no apparent options in the software to adjust this. However, this isn't a deal breaker, as I don't anticipate needing to scroll much while using this keyboard.

keyboard is very light and ıt works vey well. I am happy with it and I recommend it to everyone

Purchased this for it's small size and connection ability. I have 3 Logitech keyboards and mice. No wires.

(This review was collected as part of a promotion.) Amazing TV keyboard! Great for PC-to-TV functions. Includes an integrated mouse pad.
