      This is scaled down keyboard with touchpad that's not right under your finger tips at all the wrong times. Some people have criticized the right hand shift key for being so small, but why? The layout is clear in the photos and nobody even remotely indicated that this is a replacement for a full/standard keyboard.

      Now for the keyboard itself, it works exactly as intended. A nice setup for a home theater PC. Keyboard is almost perfect to use on your lap. I say almost perfect because there's no backlighting. There are keys at the top to control a DVD player app. I'm not sure why the top row of keys is narrower than the rest, there is more than enough room for the same size keys as the other rows. A strange design decision, but not a deal breaker in any sense.

      The unit operates via Wifi and comes with a tiny USB transmitter. Note - This transmitter looks identical to my Logitech wireless mouse infared IR transmitter, except it has a small sticker on it. If the sticker peels off there won't be any easy way to tell the difference. Just make a mental note of that and you'll be fine.

      The PC I used it with also has a USB Wifi ethernet connection. At first the keyboard did not work. After changing USB ports a few times everything started working correctly. I suspect Windows has to see the ethernet Wifi first and then the keyboard, but I can't be sure of the exact cause of the initial reluctance to behave.

      I'm happy with this product, but if it had backlighting I would have been amazed.

      This is a very complete package alas the poor quality. The touchpad is not quite responsive at first all and is not comfortable for scrolling and moving. It's color of the touchpad being almost the same as the rest of the interface doesn't help either. the function button is blue but the windows button. The alt is the to the left (opposite of mac) but what really gets to me is the right shift key being small. They have cut it in half to make room for the arrow keys. Mac keyboards, on the other hand cut up and down arrow keys to make room for the right shift key. If you do more search you will find mac and pc version from the same manufacturer for about the same price. They come with a mouse and don't have touch pad. What impressed me most about those models is using a solar panel on the top of the keyboard and eliminating the need for battery. If you want a complete solution this fits the bill. For presentations for instance but it is in no way a substitude for the keyboard and touchpad.

              Comments about Logitech Wireless Touch Keyboard K400 (White):

              Works well with the Mac Mini that's hooked up to my living room TV. I'm upgrading from a tiny Bluetooth keyboard, so the full-size keys are nice.

              Setup was super-easy, since the custom wireless dongle emulates USB instead of requiring Bluetooth setup. Just plug it in and go.

              I especially appreciate the left-mouse-button key on the top left, letting you use the trackpad with your right thumb and click with your left, making dragging easy.

              The specs were clear that it didn't have these things: but, I miss having backlit keys and rechargeable batteries.

              Build quality is a little cheap and creaky, but hopefully it will hold up if I don't sit on it.

                It's smallish, but not so far from regular keyboard spacing that it becomes hard to write with. In place of the number pad, a very useful touchpad (and an easy way to turn tap-to-select on and off: Fn+LeftClick). It may be a bit lightly built; it seems intended principally for living room entertainment use. But I use it as my regular computer keyboard and I think it's perfect for that.

                  We use it for the computer which is also attached to the tv.
                  PROS:
                  *extremely light and easy to handle
                  *the keys are a bit raized
                  *decent range when sitting on my couch and using the included extension.
                  *feels commfortable but not flimzy
                  *very well priced
                  cons:
                  *the range is only good if using the included dungle which is a bit more than an inch.

                  Verdict:
                  etremely nice and inexpensive keyboard.

                  Keyboard seems very cheaply made and not worth the money. The keys are not stable and tend to wobble as i play games and type. For the money you are better off buying a keyboard such as the Microsoft Sidewinder which in my opinion is the best you can get for a cheap budget. Would not recommend the Logitech K400

                      The Logitech K400 is the perfect fit for anyone needing a remote keyboard and mouse (touchpad). Why? Because other portable devices, like remotes won't give you a near full size keyboard for easy typing. This keyboard is the perfect choice for media centers. Could also be the perfect choice for a conference room, or any place where less is more... where you need full functionality, but want to minimize the number of devices while gaining lightweight portability. Perfect for controlling your computer from the couch. Perfect for accessing a computer device from across the room. I have looked at many devices of this kind and over and over again, I end up choosing the K400. Highly recommeded.

                        Comments about Logitech Wireless Touch Keyboard K400 (White):

                        I use this as my home theatre keyboard for my HTPC, and it works very well wit it. Having the built-in trackpad really comes in handy, so now I don't need an external wireless mouse. One hiccup i did notice is that the connection can drop off if you don't have it facing the unifying receiver directly, but other than that, it works fine. This has gotten stepped on a few times, by accident of course, and it still keeps working. I have had it over a year now, and i'm still on the original batteries, so it uses power very well.

                        I brought this to use in front of my big monitor that is hooked up to my laptop computor. The keyboard woks well except for the right and left clicks which are too clumsy to use for digital editing.

                          this keyboard is perfect for htpc, big touchpad surface, left click button on the upper left of the keyboard for hand held operation. came with batteries, so everything was ready right from the box. this thing gets great range, i tried muting and adjusting the volume in the next room of my office and it worked.

                          No more fiddly remote control.

                            I use this wireless keyboard to control my laptop and Samsung Smart TV. Initially, I was concerned that it may not work with the TV but it worked fine. Navigation speed on TV is slightly slow comparatively when I use with my laptop, but it works. Rest, it works great with my laptop.

                              I am running MythTV on a Fedora 17 platform and wanted a wireless keyboard for easy control "from the couch". For this application I did not want to deal with a separate mouse and so the integrated touchpad and the attractive price were key in the buying decision. The Logitech K400 worked out of the box with no extra tweaking required. The keyboard comes with a USB transmitter and a signal amplifier. I simply plugged the USB transmitter in and the keyboard and touchpad worked. Did not even need the included signal amplifier, even though my server is in the next room. Somebody looking for the touch and feel of the original IBM keyboard will be disappointed as it is not designed for hours of typing. For me it is the ideal input device to navigate a media center.

                                Simple setup. Economical way to have your trackpad and keyboard in the same unit. Lightweight. handy funtion-specific keys on top row (volume, transport controls). At home, my father uses this to watch movies and youtube. At work, we use it to control our smartboard system and projected presentations without having to be tied to a laptop. What would make it 5-star...better Mac integration. But overall, a great and no-brainer buy, especially for the price.
