The keyboard receives positive feedback for its quality, particularly for HTPC use, and customers appreciate its sleek design and extended reception range. The touchpad responsiveness and size receive mixed reviews - while some find the touchpad accurate and the size perfect, others report sensitivity issues and note it's smaller than regular keyboards. The build quality also gets mixed feedback, with some describing it as solid while others find it flimsy.

    Best Compact Keyboard That Feels Nearly Full Size and Fits A Small Work Surface
    I bought this Logitech keyboard about 17 months ago. I'm just posting a quick review to say it's excellent and has been a lifesaver. And if you need a small keyboard then don't hesitate to buy this one. I spend a lot of my time working in a Zero Gravity Human Touch recliner from Relax the Back which I use with one of their compatible small laptop size swing over desktop trays. The tray is too small for a regular keyboard and mouse. I tried a few different compact keyboards, and this Logitech is the only one I feel really comfortable typing on and that doesn't slow me down too much. The keys are raised nicely and responsive, and it's easy to get accustomed to the smaller size. I had to adjust to a touchpad as I had never used one, and while I still prefer a mouse this Logitech made it an easy adjustment. I love the white color, none of the writing is wearing off the keys after 17 months of use and I haven't ever even needed to replace the batteries. It's not backlit but I don't need that feature for my office. I connect it to my regular PC and use it with a desktop monitor that's on a swinging articulating arm, and it's a great set up for anyone with a bad back that makes it hard to sit and work all day. This was the final gadget I needed to make this unique configuration work, and it's really a dependable, nice and comfortable keyboard at a reasonable price. I highly recommend it.

      Having cut the cord with cable a year ago (and having written a book about it entitled: Simple Guide to Over-the-Air Free TV), I use several sources for streaming media to supplement my over-the-air TV brought in by a Mohu Leaf 50 Indoor HDTV Antenna to my TV.

      One source, my Sony Vaio laptop, acts as a media center when connected via HDMI port to my AV receiver or directly to the HDTV. I use XBMC software to stream photos, music, video and live TV from around the world to my TV, and I picked up the Logitech Wireless Touch Keyboard k400r to make that job a bit easier and more enjoyable.

      Placing the Logitech receiver in a USB 2.0 port on my laptop, and removing the tabs to the batteries that came pre-installed in the keyboard, I was up and running in seconds using a Windows 8.1 PC. Moving the cursor with the integrated touchpad is a breeze, and the keyboard has excellent range (8-12' in my living room) when paired with the laptop.

      If it was backlit (it's not...) it would be nearly perfect. While the build quality is not as substantial as other Logitech wireless keyboards I've used, and the typing action is noisy and stiff - I like it a lot. Particularly the integrated touchpad, which works well.

      As it is, its price, size, functionality, immediate pairing and user-friendly layout make it very good, and just enough for me to give it 5 stars.

      NOTE: I tried to pair this directly with my Sharp branded smart TV and found it did not work. Then tried it on my mother's Samsung smart TV - it didn't work there either! After a bit of research on Logitech's Forum, I learned this keyboard is designed to control media PCs connected to HDTVs, not smart TV functions.

      IF you have a smart TV and want to use a wireless keyboard, try the Logitech Wireless Desktop MK320 Combo or the Logitech Wireless Combo MK270 with Keyboard and Mouse which both worked when their unifying receiver was installed on the smart TV's USB ports.

      ALSO make sure that whatever keyboard you are trying to pair with your smart TV is not paired with any other device, or it won't work.

      The class is wireless RF keyboards with touchpads, which have media keys, and are relatively compact, yet usable for extended typing, and which are not prohibitively expensive. It's a surprisingly limited class, given current trends in home theaters and media consumption. I've listed another contender, below.

      First, note that I have the white K400R. The R indicates the updated keyboard, with some reprogrammable features, and which has volume controls on the F10-F12 keys. The older K400 has volume controls on the hotkey buttons, above. At this writing, Amazon offers either black or white versions of the keyboard, BUT, the black one is the K400, and the white one is the K400R.

      The keyboard layout is not full-sized. It's just a bit larger than the one on my Asus EeePC netbook. I have no problem with this size, though some users may find it too small. Some have complained about the stretch required to get to the right shift key. While it IS a stretch, the smaller overall size of the keyboard makes the stretch not as bad as it may appear. Keystroke feel is pretty good. Build quality is pretty good. You get some minor creaks when picking it up in various ways, but, picking it up with one hand -- thumb under the touchpad -- is solid enough.

      For me, a keyboard that lacks dedicated Page Up, Page Down, Home and End keys is a non-starter. For that reason, I had always avoided the K400. I decided to give the K400R a try, when I learned that it is "programmable." Well, it is sort of programmable: 3 hotkey buttons (media player, PC lock, PC sleep) and 6 function keys (F1-F6) can be reconfigured with Logitech's downloadable Setpoint software. Note that the Home button can NOT be reassigned.

      I set up the F1 and F2 keys as Page Up and Page Down. The F3 and F4 keys became Home and End. To help identify their function, I put thin strips of colored electrical tape on the button risers (I'll try to add a photo). [Unfortunately, these new navigation keys do not work with the control or shift key, such as when selecting text.] I set F5 to be WMC toggle between full-screen and window mode. F6 is set to be quick skip (aka skip ahead, aka ad skip).

      When Googling for keystrokes necessary to program F5 and F6, I discovered two things about Windows Media Center. 1) There are keyboard shortcuts available for all operations we might want to accomplish with dedicated media keys. Nice. You could actually live without a "media keyboard," if you don't mind using the control- and alt- shifted keystrokes. 2) The quick skip interval can be modified with the skipaheadinterval registry setting (exercise caution; and, Google for full instructions). Instead of the default 30 seconds, skipping ads in recorded programs might be easier if set to skip 60 seconds, or even 3 minutes.

      The next issue some people have expressed with this keyboard is that the FN key must be pressed to get regular F1-F12 keystokes, since the media and windows functions have been set for non-FN priority. Fortunately, this can be reversed in Setpoint. BTW, Setpoint may not immediately offer configuration options on new setups. It seems you must first use the software to unpair and then re-establish connection (using another keyboard or mouse), before all options are shown.

      In spite of my tendency to frequently use the F5 and F11 keys, I decided to maintain priority for the media keys. To avoid having to FN shift for F5 and F11, I set the PC lock and PC sleep buttons to provide those functions.

      The touchpad has a good feel for general use and 2-finger scroll. Pinch-zoom works, but, I've never had that before, so can't compare feel.

      There are 2 significant problems with the touchpad, which I have decided to live with. They are known issues, as they have appeared in problem reports on the Logitech support forum. 1) The 2-finger right-click often does not work. It appears to vary depending on window focus, or use of 2-finger scroll. It's so bad, I'd rather use my thumb on the right mouse button, below the touchpad. 2) While double-tap-drag does work for some things, like moving a window by the title bar, it does NOT work to resize a window. Resizing becomes a 2-hand operation, though the left mouse button on the top left corner makes it less awkward than if using the touchpad's left button.

      Some users might find happiness with the Ortek WKB-2000, currently listed on Amazon as "2.4GHz RF Wireless Keyboard with Smart Touchpad Mouse for MCE Media Center Edition". I could not get the 2-finger scroll to work. From reading reviews, and through my own efforts, I discovered there is no good driver for Windows 7, 64-bit.

      The best keyboard I've had is listed on Amazon as "RK728 Wireless Keyboard". Mine just died, and it was a great loss! Unfortunately, it is not currently available, even on the 'bay. That may be because of quality control problems. I knew mine would not last forever, and had tried twice to buy a backup. But, both failed in a few days, and were returned.

      Also noteworthy, is the Adesso WKB-4000UB. It has a great form factor, good key action, and is currently available, but, it has no media keys. Worse than that, the touchpad seems to be pretty low resolution, and, about half the time, tap to click does not register, so, I have to move the pointer slightly, and tap again. For that reason, I just use it as a backup. Mine is several years old, so, it is possible that the touchpad has been improved. Oh, and the touchpad has a scroll zone on the right edge, rather than 2-finger scroll.

      3 1/2 stars would be the best rating for the K400R.

      If you need a full size wireless keyboard for android K400 is a good choice. Unlike some of the cheaper noname models from China, this keyboard has a usable track-pad. I have connected it to a Smart TV in my cottage and we use it for basic surfing, check email etc. without having an entire desktop. It has media center keys which work without problems. It turns off automatically to preserve battery life.

      4.0 out of 5 stars Good keyboard and touchpad, however having to hold down the function keys to use F1-F12 is annoying

      A good keyboard, however in order to use the F1-F12 keys, you have to hold down the function key which is very annoying. My older model K400 didn't have this annoyance.
