Great keyboard all around 12/31/2019 11:11:41 AM

Pros: High friction base prevents the keyboard from sliding around while being used. Light up keys have various settings of brightness and light up wonderfully making the keyboard visible even in low light conditions. Keys are fairly quiet.

Cons: I verified that the Shift+w+space bar combo does not work on this keyboard, which is only a problem if you're gaming, and Shift+w+caps lock works fine, so it can be remapped.

Overall Review: Great keyboard!

Thin, illuminated, soft touch, well made 12/19/2019 9:59:59 AM

Pros: She's thin, has good rubber foot pads so she doesn't shift about on your desk, and is illuminated. Soft touch keys, that are relatively quiet. A well made keyboard.
Also, if you are tech savvy, like I am, this keyboard may be disassembled for cleaning.
Hard wired USB cable offers increased security over Bluetooth and wireless models.
Life expectancy should be about 8 years, as this is my second of this Logitech model.

Cons: You should reasonably expect the LED keyboard lighting to last around 8 years before she starts to get dim. Other than that she was still working when I replaced her with a new identical model.

Overall Review: Recommended. Pricey keyboard, but then she's high end. You get what you pay for, and I pay for quality.

As Good as it gets! 12/18/2019 2:01:20 AM

Pros: Runs exquisitely, as is, no drivers necessary, on Linux, Android and Chromebook. I Don't care about Microsoft. No software necessary.
Does not corrupt 1st password input; when using 'non character generating', hardware backlight adjust key, to wake from Suspended Linux. 1st password works! uncorrupted, every time. No "Do Overs required.
Amazing touch response.
No batteries or wireless dongle. Did I mention no drivers necessary?

Cons: Now I am wanting to replace all my other keyboards with one of these

Overall Review: This is the Linux keyboard I have been searching for years. Someone should have told me sooner!

Intentionally Broken for Gamers 10/10/2019 6:31:59 PM

Overall Review: After losing my old slim/membrane Logitech keyboard to the ravages of time, I picked up the K740. It added welcome backlighting and feels sublime under the fingers. Just one problem: W + Shift + Space doesn't work! This combination - essential in many games - was disabled by Logitech to push you to buy a dedicated gaming keyboard. Every other key + shift + space works just fine.

Avoid this like the crippled junk it is!

Not for gamers 5/28/2019 3:44:10 PM

Pros: - Well built
- works well (with caveat, see cons)
- Sturdy

I've been using it for over a year without any fault that I could find for office work. The keys have just enough resistance that it's hard to press one by mistake and it makes typing quite enjoyable. The backlight with 3 brightness settings - not including "off" - is clear and soft, properly illuminating the keys without being too bright. with .All in all, this is an exquisite product for everyday use.

Cons: - The matrix used for the keys is going to be frustrating for gamers.
- Honestly, that's the only fault I have for it...

The matrix is what's used to detect what key is being pressed. The matrix that builds up this keyboard is made in such a way that certain combinations of keys cannot be pressed. The key being pressed last in the combination won't be detected as pressed so it won't work. Shift+w+Space doesn't work. Down arrow+Right arrow (flying game) doesn't work. I've now trained myself to let go of shift when I want to jump in a game while sprinting with shift. You can work around it. It still makes me want to get another keyboard though, which is quite unfortunate.

Overall Review: I would recommend this to anyone who wants to use it for everyday office work. In that regard, it works flawlessly. I would not, however, recommend it to people who prefer a chiclet style keyboard for gaming, a field in which this product is quite disappointing. I still rate it 4/5 because it simply wouldn't be fair to rate a good product like this lower simply because it's not as fun to use for gaming. Because it's not as fun to use for gaming, though, I would not purchase this again.

Key Covers Problematic 9/1/2018 6:11:46 AM

Pros: Illumination is the K740's unique selling point. The feel of the action is akin to that of a laptop. I type with the keyboard sitting on my lap, so the weight is an asset as well.

Cons: Keyboard arrived with key covers (2) dislodged; replaced same and the keyboard has operated flawlessly since. The packing on the product was sub-par (see: comment to seller).

Overall Review: This is my third keyboard of this make and model. The first had issues with key covers becoming dislodged from light use; Logitech promptly replaced that keyboard without issue. The second keyboard worked flawlessly for seven years (business and light gaming); eventually, the space-bar failed. There are videos available that show how key-cover replacement can be best affected.
