Customer Ratings & Reviews

Love this small convenient keyboard with trackpad mouse included. Really helps save space on my desk.

The Logitech 400 keyboard was simple to hook up and use. I am pleased with it's performance and range. I would recommend it due to these factors along with it's price.

I am using it with a PC stick which is connected to a projector, very easy to use, integrated mouse pad is very useful and keys are well spaced

Perfect easy to set up easy to place batteries in it easy to start using has good distance range very happy with this product would but again if needed

Easy to use keyboard that does not require a lot of space.

This keyboard is lightweight and easy to use. It is a great value and fits my needs extremely well.

I've had the K400 Plus for around 3 weeks now, and it's served quite well as a living-room keyboard for when I hook my laptop up to the television for video calls and the like. The key travel is nice, and the dedicated volume keys on the upper right are a nice touch. Though a smaller keyboard, I actually don't feel that my hands get very cramped. (I would say I have ~medium-sized hands.) And finally, I generally like devices like these with the USB nub, making it plug-and-play. Where I would have liked to see some improvements are: - Size of the track pad. Considering there's a wealth of underneath the mouse buttons, it might have been nice for them to expand the vertical spacing a bit. Perhaps they were concerned about the user not having a space to rest their wrist, but in my own usage, I don't feel like my hand and wrist benefit from having that dead space. - Either a second set of mouse buttons on top for those who track with their thumb and click with their fingers, or making the track pad a clickable trackpad. I find that I track with my thumb about as often as I track with my finger, but maybe that's a personal quirk. - Build quality is a little cheap-feeling. For the price, though, it's hard to really complain. Should also say that I totally understand that some devices don't have (enough) USB Type A ports, and this keyboard not having bluetooth is a limitation. It's not an issue for me but just make sure you know that you need a traditional USB Type A port, or some sort of adapter, to have this work. ***NOTE*** You will want to visit Logitech's site and download the Logitech Options software if you're using this on a computer, so that you can customize the scrolling experience, pointer speed, etc. ***NOTE 2*** I connected this to my Android phone using a USB Type A to USB Type C OTG adapter, and it works on Android as well.

I love this keyboard so much. Its very smooth and friendly to use. I can operate my laptop from any corner of my apartment. Good purchase.

Nice portable wireless keyboard. I use it to navigate the web browser on my Samsung 4k smart tv. Excellent.

Very very good keyboard. Gets the job done the hooks up to my laptop gives me a bigger keyboard to use great price five star review.

I hook my laptop up to my TV 24/7 and use this as the main keyboard interface. Works great with no noticeable input lag. The left thumb button is a really cool feature and more yet to discover. I've encountered zero problems on my Win 8.1, Asus laptop - Easy to setup and just works. The off switch on the back is a nice touch too and I use it often to prevent mistypes when its laying on the sofa or the dog jumps up and starts mashing buttons. Highly recommend! The only negative would be the plastics. I haven't dropped it on a hard floor but I don't think I want to.

This keyboard has been very useful. I use it almost every day and it works well. I have had a few problems where the keys will stick but it's usually not a big deal. The only thing that I don't like about the keyboard is that it's not backlit. There is no indication for whether or not you have caps lock on either. I would like to look into getting a backlit keyboard. I definitely can say that I have gotten good use out of it though The price wasn't too bad on it either.

Great compact wireless keyboard. Battery consumption is great.

Very good basic keyboard. It synced to my computer flawlessly. Ease of use is great.

This keyboard helps me so much with the built-in mouse pad. Its easy to use.

Great accessory for my laptop. Good price, easy to use, and a must have.

I buy this keyboard for my laptop that recently had a problem with some of the keys. It works very well. It is small and very light. Easy to carry.

I use this as the keyboard for a computer I have setup as a media center the range it great and it's nice having the built in trackpad

Nice keyboard to sit on the couch with and not have to worry about wires. Battery life is excellent. Looking forward to picking up another one.
