I ordered this keyboard for work as the old one was making my fingers hurt from typing so much as it was big and clunky.
This keyboard has very low profile keys which don't need to be pressed far down to work, yet they are quite robust and not so sensitive that you keep pressing other keys when typing.
The spacing and size of individual keys is much the same as you find on laptop keyboards these days.
The keyboard itself is a substantial weight for being so small, meaning it doesn't slide around the desk, however is a comfortable weight to hold in one hand. I was surprised by this as the build quality appears to be very sturdy.
Rather than being placed in an open cavity in the plastic base, the keys are individually set, making it difficult for any muck and crumbs to get down between them.
Regarding set up, this keyboard really is Plug and Play. I connected it to the first USB port I had available in the front of my PC, waited a minute for Windows to install the drivers and I was away. The multimedia buttons and sleep button also worked without any tuning needed.
I've had this keyboard for 2 weeks now, and one of the letters has just split and peeled off. Everything else is still fine however and has reduced the amount of pain I get from typing hugely. Just disappointed my D has now turned into a small r.
