CORSAIR K57 RGB Wireless Gaming Keyboard –

Has a bit of a learning curve
I bought this keyboard on an impulse, so even though I love it, I also have some regrets…Anyway, what I love is:* The dongle (thing that let’s it connect wirelessly) can be customized to work with another Corsair products. This is why I impulse bought it in the first place sicne I already had a mouse from Corsair (the Sabre RGB Pro Wireless).* Doesn’t require batteries (comes with charging cable).* Is wireless, so you can save some cable management (another reason I bought it, my previous wired keyboard was driving me crazy).* It has a nice design and is extremely customizable with the iCue application from Corsair.* Has a very comfortable numeric keypad.* I am not a hardcore gamer, but on the games I play I notice very little to no delay when playing wirelessly.* It is very quiet and light. It has enough sound and weight to make you feel like you are pressing something. Is not too loud that you can’t use it after midnight in fear of waking up your neighbors; and not too heavy you have to destroy the key to press it.* Has a set of 6 customizable keys. Haven’t used them yet, but will soon.What I don’t like:* It is not USB-C but USB mini-B! This is my main regret as an impulse buy, so not really their fault, I should have read more carefully. My mouse is USB-C, so I cannot really use their charging cables interchangeably. Oh well.* Another issue is that the keyboard doesn’t work when turned off and connected by wire (charging). I know that sounds weird, but the mouse I have does work when turned off if it is connected by wire (charging).* Is a bit too big (is bigger than my laptop, which looks really silly), and somehow the keys feel weirdly small. I assume is just me trying to adapt to the new size and key design (they are kinda tall instead of flat, like the ones I am familiar with).* For some reason, the video buttons work abnormally (sometimes they do, sometimes they don’t, the backward and forward button usually don’t work on youtube, the play/pause and stop button do work).The arm rest is kind of unnecessary, although it does make it look nicer and less squarish (though it does make it bigger).All in all, it served the main function I wanted it for: reduce USB connections and cable space management. But I do have some regrets about some of the features.

Good but not worth the price
I ordered mine from Amazon warehouse. It was open box. Got a fair discount on it that way only it didn’t come with the wifi receiver so I had to get a refund. But that isn’t any fault of the keyboard.I however did test it with the USB cable. Old school micro usb. They don’t last. When will these manufacturers start using USB C? Sigh …..As for the keyboard. It looks fantastic. Larger than full size. This thing is a monster. The backlighting looks great though the Corsair ICUE software is lackluster and a memory hog. Lighting profiles do not save to the keyboard. The software must be running to use them. If you try to use without the software, the keys just flash. It isn’t practical so you are forced to run the app.I didn’t have issues typing like most reviewers. However the keys are very loose and clunky. I was expecting something firmer at this price. I am very disappointed. The sound and media controls work great and would be a huge help if I could use it wirelessly. I had no issues controlling my soundblasterX G6 with the volume controls.I give it 4 stars but it is likely 3. I feel you can do better. I have an Asus laptop with the Armory crate software and it is much better than the Corsair ICUE software. I might switch out to more Asus products just so everything can be controlled from 1 software. The fact that profiles don’t save without the software running is a deal breaker.

Muy buena calidad, el producto es lo que promete, quizá la batería pudiera durar más depende de tu uso, pero inhalambrico y con el brillo al Max aguanta casi 5 días. El mouse aguanta mucho más casi las 2 semanas

I researched the hell out of this keyboard before finally buying it. For the price point and features, there is bluntly no competition.What sold me:• QUIET keyboard with good typing experience• Cool-looking RGB with lots of effects!• A wireless keyboard I could swap between my computer, tablet, and phone without needing multiple keyboards (has 3 wireless modes: dongle + 2 different bluetooth devices, you toggle with FN key, PLUS direct USB)• Volume and media controls• EXCELLENT RANGE (I stream my desktop to other screens in the house. Never had a problem connecting)• Low latency for when I’m gamingThings to be aware of:• Hybrid mechanical/membrane – It’s a little squishier/has more resistance than a pure mechanical keyboard, but the typing experience is still good and far, FAR better than your average membrane keyboard.• Did I mention it’s QUIET? (if you’re a clacky-key fan, this one is NOT for you)• Poly-carbonate body – It flexes a little, but it doesn’t feel flimsy• Per-Key lighting requires wired/USB mode (but works really REALLY good). Side note: the iCue software actually works very well with the K57. I was skeptical after my experience with other Corsair peripherals, but in this case I’ve had zero issues with iCue.• RGB in wireless is still robust and has a lot of different options easily changed through the FN key, and looks great.• I can easily get 2-3 days on a charge, moderate usage all day long, RGB turned on.Simply… this keyboard is GORGEOUS! Not only that, it’s highly functional, and won’t break the bank like other wireless RGB options. As long as you’re not a clicky-key purist, this keyboard should serve you well!
