I guess I will stick with the G710+ that has keys that fall off

The keys are comfortable and the backlight is the brightest I've ever seen

I loved the keyboard at first, it was nice and light, was comfortable, easy to type on, and had nice bright backlit keys which I was so happy to have

The keyboard is quiet and the keys are responsive.

One small peeve - the music/audio key only works with iTunes or WMP

Love the illuminated keys which are motion activated.

Love the back lit keys too.

The keys are nice and clicky.

and there was no dust as I carefully kept it in a small cabinet when i wasn't using it, last week after several months of not using it thinking it might have been a glitch or something, charged it before using it and now several other keys including numbers stopped working altogether, it was good while it lasted but goddamit

sadly, the '*' key just died, and i am going to have to retire this hard-working keyboard

I like the lighted keys and no wires.

The first one I had, the number 8 key kept sticking or wouldn't work

The backlit keys also did not work once I got it up and running

if you use the wrong key to wakeup you could attack to soon, ect.

The backlight strength can be adjusted by using the appropriate keys on the keyboard, but the settings are not remembered if the keyboard goes to sleep or is turned off.

Only one time did I need to fix a sticky key

As I have limited vision the backlit keys are a necessity for me

This is a great wireless keyboard, and love the back-lit keys.

The keyboard itself is ok, the keys are nice and they have nice smooth feel to them, but I do find that I miss keys more often then on my chiclet or mechanical keyboards

Old guy here with bad eyes, so the lighted keys are great.

This product is awesome and the backlit keys are a plus when working late at night

Like the operation of this keyboard very much, the keys have a nice feel and are ideal for a touch typist

Great feeling keys, perfectly laid out with illuminated keys when you type only to save battery lifeBest keyboard I've used

Soft keys, backlight, rechargeable and never laggy.... you can't go wrong with this keyboard.

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

On the positive side, the keys are quiet, and having backlighting is sometimes helpful.

Also has an on-off switch and, after a period of non-use, the keys will go dark

It's thin, full-sized, and the keys are perfectly responsive when I type

the oversize Enter key on the number pad comes off regularly and will not stay in place

Typing is solid, no rattling keys and good feel to it.

Had to get the same one as this worked so well, is a great size, and the backlight keys are helpful.

Stupid right side shift key would stick or be hard to press down

The keys are silent and crisp, not too sensitive either

Very comfortable to type on and love the backlit keys that can be adjusted for brightness.

This one has the loud keys.

While the backlighted keys are the brightest I've ever used and have several levels of brightness, every time you turn the keyboard key lights on it reverts to the lowest setting

This baby charges fast, has decent range (though objects can obstruct its signal), and very quiet keys.

* Performance: does what it claims, offering illuminated keys at user discretion, easy and reliable connectivity, dependable performance thus far under heavy daily use, can use existing "universal dongle" to add a Logitech mouse, if desired, which would clear up another USB port (although I like my HP Mouse too much, to switch

The illuminating keys are great since I usually only use it in a poorly lit room

It lights up which is a good feature, but the keys are a little awkward to use because the key spacing is not great.

it's hard, if not impossible, to really clean the keys so they look clean

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

The main downside until now was the poor battery life (a week or two), presumably due to the illuminated keys, but that wasn't a huge deal to me

Nice weight and the keys have a very nice touch to them.

Key was sticky --shift key.

The back lit keys are not distracting and are more useful than I thought they would be

The illuminated keys is fantastic

It has silky, whisper-quiet keys that register every key stroke flawlessly

Super quiet keys and love the backlit keyboard.

Very smooth keys and functions

My old Logitech lasted for a decade and never lost a key.

About 6 months later the #9 key on the numeric keypad began missing keystrokes

Loved the auto backlit keys

Just fantastic keys.

I like the programmable keys to save time executing applications of my choosing!

One that was just missing the "e" key I put some regular AA rechargeable batteries

I thought that the rounded keys would be slightly annoying but they actually feel great

As some people have complained, the keys don't have any buffer in between

I don't miss the media keys as I forget they're even

I originally liked the backlighting, but if that fails the keys are very hard to read in anything short of bright light.

So despite the wonderful lit keys, non-sticking keys and overall silent keystrokes, the utter flaws brought on by this product being far too small and fragile means that I cannot recommend this product.

the back lit keys on mine rarely work

its a decent size and the illuminated keys really help out when typing at night

This new K800 has *much* noisier keys at full tilt typing than did the K740

Keys have a nice feeling, I like the 10-key, and the function keys work well with Windows 7 and 10.

I had this key board for a year, I fell in love with it, the soft keys and gentle back light.

One thing I have noticed is that if you look closely you can tell that some keys are more clear than the others or that the light doesn't shine through as bright though if you don't stare at the keys up close you can't tell

The keys are quiet enough for you to work in an environment where noise is inappropriate.

At other times, when I am using the numeric keyboard some of the number keys will function as if I am pressing the return key.

Every key still works perfectly and has never needed replacement

The keys being soft, yet firm

The keys are smooth and the light isn't overpowering when using it in the dark - it's just enough to illuminate the keys, but not the entire room!

I love the Illuminated keys.

The hot keys make my daily tasks easier.

The K350 is huge, takes up way too much space, and the keys are a bit "sticky" and require more pressure when typing, which sometimes causes typos (missing letters) with my style of typing

That's how I killed the C key on the second keyboard.

Love the backlit keys.

While the rest of the experience is great, this just greatly saddens me that I have a defective key now that I had to resort back to using my laptop's keyboard

The backlit keys are perfect for my office which can be dreary certain times of the year.

It is going to take a bit of getting used to since I've been typing primarily on an HP laptop where the keys are flat as opposed to the Logitech keys which are concave in nature

But here in December the keys are now falling off.

The keys are very responsive, visually satisfying, the key lighting intensity automatically compensates for the ambient lighting conditions, and there is a nice click when each key is depressed letting you know without looking that the board has received your input

There is an app you can download to see how much battery is remaining for the keyboard and how long you want to illuminated keys to last

And the lighted keys are perfect.

The illuminated keys are not bright enough for my taste

The illuminated keys are not bright enough for my taste

If you have large fingers or long fingernails, you may want to try this out in a store, first, before buying because the keys might be too soft for you.

Best Keyboard, I love the lighted keys and the soft keypads

The problem was the keys would stop working, basically shorting out because it was highly sensitive to humidity

so I have run into some instances where I press the wrong key

However, the keys are too delicate

This is not something super major but the keys are very smooth and feel of high quality and not thin and cheap.1 negative I would have is the keyboard seems kinda big compared to my other keyboard if it was a little smaller it would be more comfortable to move around with or pack in a bag for travel but far from a deal breaker amazing productSafe buy

I guarantee you will break the key.

Love all the keys and touch feel - allows for my “hard” typing to be much quieter

all drivers updated, all batteries updated.. the keys just stopped working for no reason

I didn't expect the illuminated keys would be a feature I needed or wanted, but it is nice and you can dim the light so it isn't a distraction.

I was in need of keyboard and decided to go for one a bit fancier with the illuminated keys

I had this key board for a year, I fell in love with it, the soft keys and gentle back light.

One thing I have noticed is that if you look closely you can tell that some keys are more clear than the others or that the light doesn't shine through as bright though if you don't stare at the keys up close you can't tell

Excellent, but having some issues with the wireless connection and loose keys.

When I first started using it, I had to pry the key up with a small flat blade screwdriver every time it was depressed.

the eliminated keyboard not just the keys themselves is a blessing to my aging eyes

The keys are supple enough that you don't have to beat them depress the key

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

Most seem to be expensive gaming keyboards with garish colored lights and loud mechanical keys

but I eventually broke some keys

The back-lighting didn't work consistently, the keys weren't coated or painted

The keys are slightly dished in, so your fingers do their walking pretty well, and, as I mentioned earlier, the weighted keys make for solid contact, much more so than the "clackety-clack" of hollow keys that make for noisy, less accurate use, at least in my experience

Nice keyboard, love having the backlit keys

I like the soft quiet keys

The keys are soft and quite which is a big thing I was looking for
