Customer Ratings & Reviews

I use this to control my pc connected to my tv from the couch. For that it is perfect. The keys are very responsive and the touchpad works as expected. I don't have any noticeable lag. I wouldn't game competitively like this but it is fine for casual gaming with a separate mouse. It is compact so several keys are multi function. For the discounted price this thing is perfect. I would recommend it as a secondary keyboard.

Small convenient and exceptionally good! I use it for my home theater pc and works perfectly. Good range, no lag, not too big, not too small (that’s what she said lol) good buy

Very light weight, keys are decent to type with and doesn't lose connection. I Bought this to use with my home theater pc. Works well enough but I feel like it lags a bit sometimes. But for the price I paid I'm willing to live with it. Got it on sale for 15. At that price I think it's definitely worth it.

I use this when playing Final Fantasy XIV on my PS5. It's super easy to connect and worked almost immediately: just plug in the USB and turn on the keyboard (batteries are included and pre-installed in the keyboard). It takes AA batteries and the slot is on the back. The battery cover also contains a holder for the USB so you can take everything with you. In a room where I have multiple systems and electronics emitting tons of signal, this keyboard has no noticeable lag and gets what I type on screen quickly and cleanly. No issues using the mouse, but I do with is was a bit more sensitive. For the price, it's an incredible addition to a home console setup, but I probably wouldn't try to use it for actual intense gaming.

Now that I've got you humming the Log Song, let's review. This wireless keyboard is my first foray into these kinds of devices, so it is hard to provide an apples to apples comparison. What I have been satisfied with is the quality of the device, which while it is light, it doesn't strike me as chintzy. Of course, it connects easily and quickly, as all these devices do (I suppose). There is very little lag, keystrokes and mouse movements are usually instantaneous. When it does lag it is very slight, almost imperceptible, and it does not happen often. The keyboard is small, and some of the buttons do seem crowded, but I allow for that considering the purpose of the device. I was drawn to it because of the built in touchpad, as I already have enough devices, trinkets, and tchotchkes cluttering up my living room. While I don't have a large frame of reference for these kinds of products, I'd recommend this based on my experience with it.

Amazing keyboard, lightweight and small to throw in my backpack. There is little to no lag on my pc.

very good for its price, no lag and touchpad works great

I use this keyboard to control my Steam computer. My Steam computer is connected to my TV and I'm able to control it nicely from my couch with this keyboard. The only issue I have is my room is large and I'm about 15' away from my computer so sometimes it will get a little laggy.

This keyboard is great. It has pretty good range and no lag. Great response. My son uses it on his TV to do homework and play games and he loves that he can lay in the bed and move around with no wires.

Perfect for my raspberry pi projects or when im traveling. Love that the mousepad is attached to the keyboard, no lag either!

Love the idea of a touchpad integrated with a wireless keyboard so I don't have to keep up with two things on my sofa. I love that this is a lightweight, compact all-in-one keyboard. But the love fest stops there. First, there is no indicator light letting you know if the caps lock is on. Second, both the keyboard and touchpad have terrible lag. Third, if i cross my legs and block the keyboard, the signal will not go through. Fourth, the touchpad does not work well. It frequently skips. Quite often, the scrolling is not smooth. Sometimes it doesn't register taps or swipes. The touchpad is subpar. I checked my batteries and they were both fully charged. I tried a second K400 plus and it was worse! I am using this in the living room with a pc connected to my TV. Since I am not relying on this as my main keyboard and the next model up costs three times as much, I decided to keep it. :(

I bought this to control the computer attached to the TV. It works well at long range and have no issues with lag or connectivity.

Easy hookup and use. No problems or lag. No cord or mouse

Got this for our pc that we setup in the living room to watch shows and movies since we don’t have cable or anything, plus the keyboard and mouse attached to the pc aren’t long enough to reach where we’re sitting, so we bought this. Trust is, it can get very annoying having to constantly stand up to click on to the next episode. We can’t wait for the little countdown, but we are impatient! We saw this since it was wireless and it works just like it says but it has a major lag. We even downloaded the softwares and still nothing helped. Not sure if it’s our pc but the OS is constantly updated, so there shouldn’t be a reason with the lag. We tried a free app on iOS that acts like a mouse and there is no lag between that and the pc. That worked better but it kills phone battery very quickly Had to return it unfortunately. Hoping to find one that doesn’t have that issue.

I love having it all in one. It dose lag occasionally.

I got this to use on my Shield. Works pretty good but can be laggy at times don't know if it's the keyboard or Shield it's like it needs to warm up before it will start working right. But beats just using the remote.

Install and setup was a pain. After installing software, it still did not work. Rebooted and finally worked, but install process didn't state to do that. Nor did it appear correctly in device mgr until install. I purchased this to use from 8ft away from computer. When I got it working, it seemed OK. Had a lot of lag, especially when typing a lot. Track pad did not have as advanced settings as I would have liked. It may work for some situations, but did not work for me.

Bought a second one for downstairs after using it. One i had before had some lag but this one works like it should without a glitch

Good little keyboard. Slight lag, but nlt terrible.

Works great, lags a little here and there but does it job
