5 Stars
Attractive, well made, relatively quiet back lit full, corded keyboard.
This is a very attractive and comfortable keyboard. The keys are fairly responsive (I'd rate them a 7/10 on responsiveness) and have a feel halfway between laptop and regular keyboard. Their noise is diminished when compared to most gaming keyboards but there is still a distinctive soft sound (it's actually quieter than the sound your fingers make if you just lightly drum/tap them on a keyboard without actually typing. Except for the space bar and enter key which are a little louder).Aesthetics-wise, it is very attractive, the clear plastic edge gives it a nice finished look (though it's of course functionless and breakable, it would protect the keyboard itself and is a seperate molded and attached piece. The lighting is customizable to four settings - off (num lock and caps lock remain on at full brightness at any setting), and then backlights on- low, mid, and high. In general I prefer low lighting and have sensitive eyes and get migraines, and the low setting is pleasant, the higher settings are fine unless you're in the pitch dark and then It's too bright for me. In bright light the top setting is still nice and visible.The keyboard has all the functions and options like print screen and page up and down and mute/volume controls that I need. I haven't used all of them yet.The palm/wrist rest is not padded but is comfortable and does have a "soft" feeling coating. It does has sturdy fold out upper feet.The cord is approximately 71 inches (180 cm).This is a very slim and comfortable low-profile keyboard that is full size and has great back-lighting options. If it came in multicolor backlighting for a similar price I would've purchased that one as well.I bought this for a new Lenovo Y910 AIO Win 10 which hasn't arrived yet (thanks UPS for making me wait 3 MORE days now when I paid for 2 day prime shipping), but I tested it on my MSI GE70 laptop running WIn 7 Pro and it was literally plug and play, worked instantly.The bottom row of keys (ctrl, windows, alt, spacebar, fn, ctrl, are much taller/raised which is a little weird at first (arrow keys and number pad keys match the rest of the low profile keyboard). I may just be noticing it because I have damaged extensor tendons in my dominant left hand which limits how high I can lift 3 of my fingers. Time will tell if I get used to it and stop noticing it.I've uploaded many photos, one is a composite showing all lighting settings. The differences are much more apparent in person than I could capture on camera.

1.0 out of 5 stars Got a dodgy one, not as pictured.
Reviewed in Australia on August 5, 2021
I've got one of these already and LOVE it, but have broken a couple keys so wanted to just buy new and store old one for future spare bits. This one has come with some keys not doing the function listed on them, tiny as shift key with a duplicate key next to it (again not doing what's listed on the key). Most of the keys near Enter don't do any one of the 4 the functions that they state and many just have other functions that cannot be done. Not sure what's up with it - can't just state international though, as if I were to touch-type and use normally, it all works. Easier to swipe the 2 broken keys off this and use it for spare bits.

Sad when you don't get something exactly as pictured.

Photo is of the keys which did NOT do what is listed on them.
