Review: My HTPC's best friend! - The K400 is a wonderful compliment to HTPCs. I really can't image mine without it! Cheap and full functioned. Good size and sufficiently durable. Function Perfect! Has a dongle that will remain powered when the PC is sleeping. Any keyboard movement will wake up the PC making it ready for action. Ideal for HTPCs! I have an SSD drive so within about 5seconds of touching the keyboard, I'm ready to start watching something! Helps save a lot of energy to let my PC sleep and only wake when I want it to! There are many built in short cut buttons on the keyboard that are great for HTPCs, these include volume control, playback control. I understand that the new version of the k400r has removed these so if you want to use this for an HTPC I would recommend getting an original. They are also a bit cheaper. Size Almost perfect. This is actually a huge deal for me. I thought I wanted something really small like a real remote would be, but I tried the Lenovo and Logitech handheld keyboards and I was really disappointed with their ease of use(I don't have particularly large fingers either). This keyboard had just the right size for typing and yet isn't too big to be weird for a coffee table. There is probably a lot of personal preference built into "which size is right" but many people seem to agree that somewhere around the range of the k400 is about the right size. How else is it's popularity explained? Only thing I don't understand is the Van Halen design on the trackpad. (But I can live with that) Durability While not exactly built like a tank, this is durable enough for a couch area. I have accidentally sat on it a few times without issue. It probably could be a bit stronger but it is plenty durable. Range This is the only area that I've had some issues with. I have a mid-tower case placed on the floor next to my TV. The dongle is inserted in one of the front panel USB ports (about 2feet from the ground). I tend to place the keyboard in my lap when using from the couch. Sometimes I have my feet up on the edge of the couch so that they are blocking the line of sight to the receiver. At these timed the keyboard stops responding even though I'm only about 15 feet away from the receiver. Once I move my leg, it starts working again. I wish the receiver were more sensitive or the keyboard blaster stronger (perhaps adding a second blaster in the keyboard would solve the problem?)
Review: Excellent small wireless keyboard - Got this on a great sale, not sure if I like it as much for the full $39.99 price. Small keys, reminds me of a small laptop keyboard (before everything went chicklet style). Backspace and Enter (CR) are pretty small but I can make do. Got my typing up pretty fast without much effort. Comes with 2 AA batteries. Thanks! What I REALLY wanted was a tiny wireless keyboard. This is as close as I could find which has the attached touchpad. I am not a fan of touchpads, but this is probably a positive for people wanting to use this from their couch on their HTPC. You can disable tap to click and gestures, which I did immediately. FN plus left click turns off tap to click, FN plus right click turns off gestures. Some people may like the gestures (like pinch to zoom etc) but I found it annoying when trying to use the trackpad like normal and it interpreted it as some other command. You cannot (or I have not found out how to) disable the touchpad entirely. However I think I can live with this since it's on the right and not under the keyboard where I would be hitting it constantly (like on my laptop). Nano receiver is very tiny, and it also includes a tiny extension if you need it to stick out some from the back of the computer. Installed in XP and 7 instantly without needing any drivers. If you want Setpoint you have to download it, they didn't include a CD in the box. Not a huge deal. I'm not likely to use any of the advanced features (key re-mapping, gesture settings, etc) that require Setpoint. Range seems good. Plugged into HTPC and works fine 10-13 feet away which is perfect. I didn't test farther than that. It doesn't interfere with any of my other wireless Logitech devices, which is a big plus. I also have a K800 and a mouse that use the unifying receiver and I was worried about crosstalk. No problems at all. So in short, I like it. Don't mistake it for a full sized keyboard, you may not want to crank out any novels on this thing. But if you need small footprint or to use in the living room, this is a winner.

## Questions & Answers

**Q: cn i use this keyboard with my classroom pc tower?**
A: if it has a USB port and you have permissions to instal a device...yes.

**Q: Fire tv  compatible?**
A: I don't have Fire TV, I uses it with my laptop that connected to HD LED TV.

**Q: Hello this keyboard is for android tablets and phones ??**
A: This keyboard is for computers with USB ports, as it has a USB transmitter.

**Q: Will this work if i use Samsung galaxy s21 and tv monitor?**
A: It's not a bluetooth keyboard. It has a standard USB transponder that you have to plug in to your device. Any device that you can use with a normal USB keyboard you can use with this keyboard. You can use it with a PS5 or most smart TVs. But probably not with a phone, and not with a TV that you're just using as a monitor. You'd have to plug it into the computer that you're using with the TV.

### ⭐⭐⭐⭐ Almost perfect, but could have been better.
*by S***Y on August 22, 2013*

I ordered two of these keyboards because the prices were less expensive than Samsung's own SmartTV keyboard in addition they work with PCs and Macs. I plug in the unifying USB receiver into an available USB slot on the back of the television and the television instantly recognized the keyboard and it worked pretty well. Both the keys and the trackpad moved the mouse pointer on the television easily. Some of the Fn function keys such as F7 and F8 replicate channel changing buttons, F8 brings up the television's menu. It just takes a little trial and error to figure out what function they perform on the television. I also have a Dell Laptop with a Logitech mouse that uses an identical unifying USB receiver. I didn't not have any problems mating the keyboard with the receiver on the laptop and the keyboard and pad worked flawlessly. The one thing about this keyboard that bothered me was the right handed shift key. My bad really, I should have noticed the layout before ordering. I'm a full keyboardist and the right shift key is practically useless because it is so tiny. This keyboard would have been perfect had they decided to move the arrow keys underneath the track-pad. There is plenty of room for the arrow keys there and it would have given more room to put a full-size right-hand keyboard. If you type with all ten fingers, the right-hand shift key may bother you. On the positive note, since the Samsung television works with the unifying receiver, it would seem that any other Logitech wireless keyboard with a unifying receiver would work with these televisions. But finding a small one with a track-pad might be difficult. For this oversight, I took away one star. By the way, the Samsung television I paired this keyboard with is a 2013 model Samsung UN55F6400 55-Inch 1080p 120Hz 3D Slim Smart LED HDTV. A friend of mine has a 2011 D8000 series and I will bring the second keyboard over to his house and see if the keyboard works with these earlier televisions. I'll update my review when I find out. Update 8/25/2013 =============================== I had the opportunity to try out the second keyboard on Samsung UN55D8000 55-Inch 1080p 240Hz 3D LED HDTV (Silver), Samsung UN46D6400 46-Inch 1080p 120Hz 3D LED HDTV (Black) and a Samsung UN32EH5300 32-Inch 1080p 60 Hz LED HDTV (Black). Of these three television sets, only the UN32EH5300 recognized the keyboard. This leads me to believe that this keyboard will only work with 2012 models and newer and not the 2011 Samsung TV. So if your Samsung television has a letter "E" or later letter in the alphabet in the 5th character position of the model number, this keyboard will likely work with your television. If it has a letter "D" or preceding letter in the alphabet, you are probably out of luck :( I hope this helps anyone with 2011 models and earlier. If you have a 2012, you are probably good.
