I also love the fact that you can use just one dongle for the Logitch mouse AND keyboard.

and I love the fact that I no longer have to worry about charging

I love the shape of the keys, the fact that it has regular key placement, no idiotic changes with HOME/DEL/Arrows and other keys

I LOVE the fact this is a backlit keyboard.

, I like the action and the fact the back-light keyboard comes to like when you place your hands on the keys

Anyway, I like the fact that the keys light up when it sees your fingers approach, and the full size format makes number keying so much easier

Love the touch of the keyboard and the fact that it lights up when typing.

I like the fact that only the characters on the keys light up when your fingers are about an inch above the keyboard

so I love the fact that the keyboard lights up, upon waving by hand over it

I love the fact that I don't need to be frequently replacing batteries in the keyboard

Especially like the fact that it is rechargeable.

I love the fact that it only lights up when I move my hands over it

I also like the fact you can replace the rechargeable

and I love the fact that the letters and numbers light up for easy visual appearance

Love the fact that the keys light up

Great battery life, love the backlit keys, and I like the fact that the sensor will activate the board whenever if senses hand near/touching

like the fact that it is illuminated but its not the best, just one a only a few on the market.

While I absolutely love the back lit keys and the fact that the keys do not stick (which has been a consistent problem I've had with other Logitech keyboards), the largest and irredeemable flaw in this product is it's size

But I miss not being able to program more keys as well as the fact that the S510 also had more keys directed to specific commands

but I love the fact that you can recharge it

The keyboard works both wired and wireless, a fact which Logitech fails to market

This is a great keyboard and I love the way it responds to typing, the fact that it lights up and is

The fact that it is has a rechargeable internal battery instead of AAA's is an added bonus I wasn't even aware of until I opened it.

Very smooth and that fact that it would light up made it that much better

I like the feel, and the fact that the keys light up after you press the first one

I like the fact that, as you raise your hands to the keyboard, it lights up but is dark when not in use (conserving battery usage).

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

, the "c" key decided to either not work at all or generate an unending stream of "c"s.

n’t hate my old keyboard it just broke
