    • Perfect for use with my Samsung Smart TV
Style: PLUS Pattern: Floral
I have two 6 Series (MU6290) 40" Samsung 4K Smart TVs that I purchased at Costco, one in my office and the other in my master bedroom. For about $19 I purchased a wireless keyboard and mouse combo on Amazon to use with the TV in my office. They use a single unifying USB reciever and work great, just plug and play. The only thing I found I didn't like was having two devices to keep track of and having to switch between them to point and input data. I saw this keyboard as an Amazon Deal of the Day two days ago and just received it, in fact I'm writing this review with it while sitting on the bed and using my bedroom TV. It turns out to have been a very good purchase because it works great! I merely plugged the unifying USB receiver into the first USB input on the back of the TV, turned the keyboard on and started using it, true plug and play. And boy do I love using the touchpad to cursor around instead of having to switch between the keyboard and mouse like I do in my office. In fact, even though the keyboard and mouse work fine on the TV in the office, I may end up buying another K400+ to use in the office, it's "that nice" not having to use two devices. I know the K400+ is advertised as a device for using with a computer connected to a TV but I read other reviews where it was being used directly with a smart TV without a computer and, even though it works great with my Samsung, I can't speak to whether it works with all smart TVs, though I expect it should work with any of the later Samsung Smart TVs which use Samsung's Tizen OS. I don't know if it works with the other two major Smart TV operating systems, WebOS & Android. It's light, seems well made, has a QWERTY keboard with nice key response and feel and is spaced fine for touch typing. It's great for basic input and I'm finding out more about how it functions with my TV. For instance, I found out holding down the CTRL key while cursoring moves the cursor one word at a time, holding down the SHIFT key while cursoring highlights one letter at a time, holding down the SHIFT + CTRL keys while cursoring highlights one word at a time, etc. These are familiar, however I've discovered by playing around that other keys and key combinations do things but the result may not necessarily be what I expected, but I'm the type who likes to play and learn and will thus get even more use from this keyboard as I learn. For example, just discovered esc key is equivalent to the "back" function when used in your browser. I can mention the media keys, previous chapter, next chapter, pause/play, volume up & down don't work with my TV. I'm sure they do if the keyboard is connected to a computer that's connected to a TV, as advertised. However this keyboard is perfect for anyone who only simply wants to point and input, especially if you only want to use one device! Overall I'm "extremely pleased" with the K400+ and am so glad I decided to give it a try. Of course the only thing I can't comment on is it's longevity but I hope it lasts a good long time because I love this thing! ... show more

    • Tough keyboard
Style: PLUS Pattern: Floral
Do not understand any bad reviews. I use it like normal, no issues at all. Works perfect. Good size, just right. Worth every cent but a little expensive. Trackpad works flawlessly. Fast typing. Has taken a lot of falls, no damage.

    • Good luck to gaming peripheral companies making a better keyboard than this one.
Style: PLUS Pattern: Floral
First off this keyboard performs fantastically. I like the touchpad it's responsive. And I like the keys they're a little squishy but they fire and they work. I bought this keyboard to work with my steam deck. It will work with pretty much any handheld that you connect to it. But you're going to need some kind of dock in order for it to work because it includes a IR or whatever we had before Bluetooth connector that you have to plug in. So this means if you are buying this for your steam deck you will not find it in your Bluetooth options. It means that it only works when it's plugged into your deck. Other than that connectivity is a snap it doesn't require any extra downloads. It even works with Linux seamlessly. That being said, given that I live in a dark apartment and I have not been able to purchase extra lighting, a lighted version would probably be a good idea. That being said overall it is a good keyboard and does what it needs to. That being said it is not the type of equipment that I would probably want to trust with my life. So taking it on any ill-fated submarine rides is probably not a good idea. I would probably trust it if I needed to contact emergency services with it though. It's solid enough. And in a society where everything is built to make a profit, I think that's very important to remember. You want things to last you don't want things to break down the moment your warranty runs out. Again in terms of appearance the gray color doesn't really bother me all that much. The fact that it's not very well lighted matters to me. But I think that RGB on a wireless keyboard is pretty silly, Microsoft did it once or twice but I think I had to recharge that keyboard thousands of times because the RGB would just suck up so much power. I think a low-powered lighting that was still bright but required less energy would probably be helpful. Probably ideas for future keyboard designs for companies to mull over. I wish them luck in making a better keyboard then this one. Maybe that in itself is what you needed to hear. Good luck to companies making a better keyboard than this one. Because it's solid. ... show more

    • Just buy it
Style: PLUS Pattern: Floral
I bought this keyboard back in 2019 for my living room media setup, and strictly speaking, this is one of the most useful tools I have ever purchased. Here is why it earns a perfect 5 stars: Insane Battery Life: I am not exaggerating when I say this thing hardly ever uses batteries. In the 5+ years I’ve owned it, I can count on one hand the number of times I've had to swap the AAs. It just keeps going. Reliability: It has never failed. Not once. No connection drops, no lag, no stuck keys. It just works immediately every time I pick it up. Perfect for HTPC/TV: Having the built-in touchpad is a game changer for controlling a PC connected to a TV from the couch. It’s lightweight, comfortable to hold with two hands, and the media keys are exactly where you need them. If you need a keyboard for a home theater PC or smart TV, just buy this. It is the gold standard for a reason. Pros: Unbeatable battery life Extremely durable (survived years of couch use) Plug-and-play reliability Cons: None. ... show more
