I don't know what the different is about this one in particular, but there is definitely a design flaw that allows too much filth to enter underneath the keys.

BUT-There is a major design flaw.

It is a design flaw of the keyboard.

The K800 is particularly susceptible to smudging, though it hardly constitutes a major design flaw since it occupies a small portion of the K800's face

I've waited to make this review in the event a design flaw or a problematic use case might surface

If it weren't for this major design flaw - It might have been a 5 star.

like it =D worth every

Just out of the box, for the first time, the E and the A weren't working

A big thanks, Logitech!(curious, I always engage tech workers, as I once was

Oh well I soon enough realized this is not a waterproof

I did not bother Amazon because well I had a 5 yr full warranty with SquareTrade

The K800 is smooth, but not quite as quiet as I anticipated.

Really disappointed as I liked everything else about it.

It worked just as well in the BIOS screens as it did after booting linux, so I can't see anything wrong with it

I also really appreciate the off/on button as it allows me to turn it off at night so if my cat walks across the keyboard, she doesn't wake up the computer and type random characters

that only reactivate you you actually type something and the first thing you type is lost as it is turning the lights back on

I've had this thing for over 5 years and it works just as well as when I first got it

Oh and ontop of that, the sensor for the backlit keyboard doesnt exactly work as it stays on

Built-in sensors detect your hands as they approach the keyboard and, in turn, toggle the backlight on and off; the keyboard lights up when your hands are roughly four inches away, causing it to brighten up as you reach for it

Works as

good as that makes it ezier than getting used to a revised new fangled change in the new K800

Not a big deal, as it's easy to just plug it in.

It's fully charged, clean as
