I just bought this item, so I may change my mind with time, but so far I like it.
If there had been a EU/Swedish version of this with keys labelled and silent red switches I would have gone for that. The dip-switches gives you a good set of options for the function keys and the layout for all extra keys is fairly comfortable. If you use arrow keys + home/end or page up/down a lot it may take some time to get used to it.
The keyboard is as advertised, build quality feels solid enough, the switches are nice and quiet. The only negative thing is that the keyboard cable is fairly short, roughly 1,5 meters I think, which is probably good if you intend to use this keyboard with a laptop. If you intend to use it for a stationary computer you may want to buy a longer mini USB cable.
