When I first un-boxed this keyboard I thought it might be a little too small. Although the keys are full size, overall the keyboard is quite compact, and therefore somewhat similar to a laptop keyboard. This was a disappointment for me as I like the big clunky 'model M' type keyboards, but this particular wireless keyboard has won me round.
There was no fuss at all setting it up: insert batteries, insert receiver and it's done. No driver install needed on Windows 7, and all the hot-keys worked automatically. Typing feel on the K270 is very much standard, it doesn't feel cheap like some. With the flick-out stands the keyboard is held at a 8 degree angle (apparently) and this means your wrists rest (somewhat) comfortably on the desk. The build quality seems okay. If you try to bend or abuse the keyboard it doesn't feel solid, but that isn't normal usage I suppose. One big plus is that apparently the K270 is spill resistant (liquids drain out of holes in the bottom rather than into the electronics), but I haven't had cause to test that.
There are only a few complaints from me. Firstly there are no scroll-lock or num-lock indicators, and the Caps-lock light can be a little temperamental in my experience. There's a keyboard on/off switch on the front that is a tiny bit fiddly, but is also a bit useless anyway as apparently the power-draw when not in use is very low. Also, amongst the hot-keys at the top of the board is a key to power off or put the PC to sleep. Through clumsiness, this gets knocked a fair amount causing an annoying wait to wake the computer up. My final, but perhaps more important issue is that the signal to the receiver isn't the strongest. The advertised working distance is 10m, but I've found this is very reliant on line of sight.
Overall though the keyboard serves it's function well. It's a proper full sized keyboard with wireless connection that can be set up in seconds. It isn't the absolute best for typing, but few keyboards are and this one is still pretty good. Rather than the office, this model does well in a modern home environment. An example of this is if I finish typing a document, I can then easily move to the sofa, switch PC output from monitor to TV and use the keyboard as the remote. In that sort of situation, the compactness and media hot-keys are especially useful.
