Overall Very Good 3/27/2020 9:41:42 AM

Pros: Excellent readability
Wired reliability
No auto-dimming
No software needed

Cons: Non-removeable oversized "wrist rest"
Physical dimensions of the keyboard (not the box it comes in) are unpublished. Like surprises?

Overall Review: What with Marketing having taken over New Product Development, it's a miracle we can get a decent product at all. Logitech keys are by far the most legible keys available. Game players don't care because the only need to press the Gun key over and over, but for the rest of us, readability still counts. Readability DOES NOT mean BIGGER. It means sharp, crisp and clear, just as it does on any product. Ignore the keyboards that say "For Old People." They only have huge, fuzzy characters.

Logitech's software reliability/usability isn't what it once was, so it is a blessing that this keyboard doesn't need any software. "Enhanced Features" look great in the advertising, but using them is not a joy. I've tested the MX Keys and the MX mouse, and they are all talk. The keyboard turns itself off when you're using it, and the mouse cursor sticks. The K740 defaults to traditional F-key operation, and the 4 (not 3) light settings are manual. No dimming!

Gamers think the keyboard is a lamp. Marketing people don't understand the product. QA is gone. The K740 may be one of the last readable, reliable keyboards around.

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!
