I bought this to use with a small 'under telly' PC that's mainly used for a bit of web surfing and watching downloaded iPlayer content. The PC runs Ubuntu GNU/Linux and I already had a wireless keyboard/mouse combo which worked usually, but suffered from reliability issues - the mouse had a habit of going crazy unless kept close to the receiver (like 1m away). Plus it was heavy and used loads of batteries.

So I was after either a trackball or trackpad keyboard. I happened to see this one first and the price was reasonable so I bought it.

Initial impressions were excellent - I plugged the tiny usb dongle into the PC and rebooted. First off, this keyboard works with the BIOS so you can alter settings without plugging in a different one.

Secondly... it just worked with Ubuntu. Straight away, with no fuss, from a distance farther away than it's possible to read text on the TV screen. No faffing with drivers or anything else. Phew :)

The keyboard layout is a little quirky, but no worse than many laptops. As this is smaller and [much] lighter than a normal keyboard, the large trackpad takes up the space where the number keys would usually be. Also the enter key is rather small and some of the auxiliary keys are scrunched up or moved around a bit. Page/up down and similar are accessed via a function key but this is all clearly marked on the keyboard and easy to get used to. The keys require a fairly firm press to register - if you're a light typer you might find the od drped chrcter.

The large trackpad is very responsive and works accurately. I have no problem clicking on menus and buttons and so on.

I have numerous wireless keyboards due to my continuous search for a better keyboard, and after using the Logitech K400 I will look no further. It satisfies my needs 100%. Yet some may want the numeric keypad, which in this case is replaced by a smart trackpad. I never fancied trackpads, yet logitech have done a great job.

The build quality of this keyboard is top notch. I was at a computer store the other day and most of the keyboards felt so cheap and flimsy in comparison to the Logitech K400.

Usually one has to find a compromise between size and usability. Compact keyboards usually end up in a lot of typo errors due to the proximity of the tiny keys. Not in this case. This keyboard is compact yet sports a great layout. It does require some getting used to as it still is a compact keyboard, yet having used it for just a few days I find myself typing much faster than on my previous full fledged, same brand, backlit keyboard.

Some have reported issues with the trackpad not responding. This is generally due to software / computer configuration. Downloading the latest trackpoint drivers from the Logitech website should solve the problem. I had this issue initially yet after installing the drivers it works a charm.

I really like the pinch to zoom and two finger scrolling. There are other features I have yet to discover and program.

The wireless range of the keyboard is very good, offering seamless connection for several meters. Usually I would have to place the dongle on the front of my desktop computer in order to have a good connection, yet there are no issues at all in this case.

Good wireless connection (3m, direct line of sight, no dropped keypresses etc.)
Good battery life
Helpful addition of extra left-click button at top left corner of keyboard

Tap-to-click WAY too sensitive (randomly selecting text/files/desktop shortcuts, dragging and dropping files, following links etc.)
Tap-to-click on/off setting in SetPoint software does not work properly (keeps switching tap-to-click back on, this is a documented problem and Logitech seemingly uninterested in sorting it)
Tap-to-click setting ignored completely in Firefox. Nothing you can do to prevent the hypersensitive tap function screwing things up when you're trying to browse.

Bottom line:
Great if you're only using it for XBMC etc., but if you want to also use it for web browsing, typing the occasional email or whatever then you are going to have a very frustrating time. The tap-to-click problem is a showstopper for me. There is a workaround to permanently switch it off (make config.xml read only) but this seemingly is ignored when in Firefox anyway, plus it would be nice to actually have a working, non-hypersensitive tap-to-click functionality. Not holding my breath for Logitech to do anything about it any time soon. It's always the same story with Logitech: decent hardware let down by persistent software hassles.

Would I recommend it? No.

Bought this to use with a Samsung ES5500 Smart TV. Plugged it in and it worked straight away with no problems. Makes the smart TV features much more useable. It's light and not too robust but I don't intend to throw it around the room anyway.
