The keyboard is a good size, comfortable and nice tactile response and feel to keys.
Russ Griggs
It even has a "handy" left hand mouse click button (top left) with a right hand mouse pad, for quick two handed mouse control.
Jon B.
I have a computer hooked up to my bedroom tv and the computer is about 20 feet away and the keyboard works perfectly.

Although there are a lot of promising ways to enjoy online content (web browsing, YouTube, Netflix, etc.) on your TV, the best one I've found so far is ... a computer.

The Logitech K400 is clearly designed with this setup in mind, giving you full control of a computer in a couch-friendly form factor. Surprisingly, it seems to be one of the few such input devices with a (near) full-size keyboard instead of a tiny thumb-sized one. Obviously, that means it's much larger than a conventional remote control, but it's also much more usable. It looked like exactly what I wanted, and at a reasonable price, too.

The K400 features a fairly attractive, clean design (aside from the odd "random lines" artwork on the trackpad). It's much lighter than I expected, which is nice, but it's also not incredibly sturdy. The build quality is fair for the price, I'd say, but doesn't seem likely to withstand a lot of abuse.

As long as you don't plan on writing a novel on your TV, the slightly-smaller-than-full-size keys are pretty usable. They aren't backlit, though, which would be especially useful in a dark living room. On a semi-related note, the Caps Lock key doesn't light up, either ... but you don't use that key anyway, right?

One very handy feature is the additional left-click button in the upper left corner, which lets you operate the trackpad with both hands or thumbs. It's a lot easier to click or drag with your left hand as you move the cursor with your right hand this way. The trackpad also conveniently offers Mac-style two-finger scrolling.

Other nice touches include an on/off switch, and a slot behind the battery door to stow the teeny tiny USB receiver dongle. It also ships with factory-installed AA batteries, which is always appreciated.

I bought the Logitech keyboard to use with my new Samsung UN46ES6150F LCD TV. The television is internet connected with a web browser, but trying to type anything using the arrow keys on the included remote was terrible! So, I did a little research (very little) and quickly ordered the keyboard.

The keyboard is almost full size with nice keys. Very tactile with great feedback. The touchpad is quite large and responsive. The keyboard is NOT bluetooth and comes with its own USB dongle (and batteries!). I plugged the dongle in the back of the TV and it immediately recognized the keyboard. What a difference....typing and navigating on the TV now is a breeze! I walked into an adjacent room to test the range and even at around 25 feet or so...no problems.

I'm happy with it.

UPDATE (7/19/2012): The keyboard is not bluetooth. It does come with it's own dongle, and you must use it. You will not be able to pair the keyboard with another bluetooth device. It will only communicate with the USB dongle included.

UPDATE (10/10/2013): Added the "NOT" in front of "bluetooth" above.

Color Name: Black
Logitech seems to want to create a device that is small enough as a home-theater PC remote but still big enough as a regular PC keyboard & mouse. Does cutting it both ways work for Logitech? This is currently the #1 best-selling keyboard at Amazon, so maybe it does.

Most people would likely use Logitech K400 as a HTPC remote to be used on the living-room couch. A HTPC remote differs from a regular remote in that it is more "PC-centric". It is made for computer users who want to view their media on their HDTVs and sound systems, while still sticking to their favorite Windows or Mac interface.

The K400 is light, weighing only 1.1 lbs, lighter than an iPad, so it should be couch-friendly. Its wireless range is good, as I have no connection problem within 20 feet away from the PC.

The touchpad is fine for basic mouse clicks and navigation. It has no scroll zones, and it doesn't support a lot of gestures. You can single-tap for left mouse click, single-tap-and-hold for drag, and double-tap for scroll, and that's it. There is no gesture for right mouse click or middle mouse click (many laptops can do this). You cannot drag-lock, and that means when you drag something on the screen, your finger has to be always on the pad. To adjust the speed of the mouse movement, you can use your operating system's control panel or Logitech's Setpoint utility, which is not included in the package but can be downloaded at Logitech's website.

You also cannot two-finger-pinch-zoom on the touchpad like you do on iOS devices, MacBook, or newer PC laptops. And that brings me to another topic.

When you use the K400 on a couch looking at your TV screen, suddenly you realize you are not as close to your TV as you are to your PC, and you need to magnify the screen.

Color Name: Black Vine Customer Review of Free Product ( What's this? )
UPDATE - 12-18-2013: This is probably the best piece of electronic equipment I've ever used, as far as longevity goes (got it 2011). Between my wife and son, this keyboard has been dropped, banged, flipped, and otherwise abused more times than I can count... and it's still working perfectly. A must for HTPCs.

Original Review:

I wanted to add my own review to the Linux camp, and confirm or add to what others have said. I'm coming at this review from an out-of-the-box functionality point of view--I'm not going to dive in and compile drivers to change anything. Here's what to expect with the unaltered product:

- Overall, I'm giving this 4 stars because it worked with Ubuntu 10.4, right out of the box. I simply plugged in the dongle and was good to go. It's light, small, the keys are responsive, and the single- and two-finger touchpad functionality (scrolling, etc.) works perfectly.
- Because it's light, the body of the keyboard feels just a little flimsy, but not in a "this is going to fall to pieces in two days" kind of way. I prefer the lighter design, to be honest.
- Some of the keys are smaller, so you might find yourself making some errors until you get used to the layout. It's nothing to scream about, though. For a "couch keyboard", I think the key sensitivity is perfect, and I didn't find myself constantly having to watch my typing.
- This might seem like a weird point, but I love the fact that this keyboard can stand on its top edge. I can slide this on a shelf with other items, and it won't slam down if those items are removed or jostled.
