having only ever used laptop keyboards and cheap and cheerful keyboards that come bundled with desktops, i have to say that this is a drastic improvement on those, the keys are nicely responsive and have a pleasant feel to them, as in they have just the right amount of resistance without feeling too stiff.
it doesn't require installation of separate software, just plug in and the drivers are installed automatically. the media keys are a nice touch, saving me having to flit between windows all the time, as is the inclusion of a numeric keypad (my laptop doesn't have one, making it a pain if i need to use the calculator, another useful feature is the inclusion of a calculator button which opens up the windows calculator)
the only real negative aspect of this board is the clack the keys make, not a big problem in itself, but does lend a certain cheap feel to it, but if you take your time typing and use a firm touch it does go away, but who want's to type slowly just to keep noise levels down?
i can't really comment on the waterproofing of this product as i don't tend to go around spilling fluids on electronics :D but its a nice idea and one that gives me the added security of knowing that if i do spill anything on it, it'll survive without any damage.
it has a really handsome finish and although it is utilitarian in its style, it will compliment any computer that it will be paired with.
the delivery was pretty good, not brilliant, but that was Royal snails (sorry, Royal Mails) fault as they didn't arrive at our house while 2:45pm, 3 days after the date upon which it was supposed to arrive, it came reasonably well packaged, not the best, but certainly not the worst (that award goes to certain sellers of hard drives)
if you want a decent quality keyboard for under 20 quid, you won't go far wrong with this one. i highly recommend this to anyone looking for a low cost yet good quality keyboard.
