Brilliant mechanical Switch Keyboard

- Reviewed in the United States on September 17, 2017got it on sale. This seems to be the same as the G413 but without backlighting, and without the usb passthrough. I bought it to replace my 15 year old "windows 98 keyboard" that was originally $10. WOW. what a difference.
I didn't need this keyboard per se, but I was tired of the sticking keys and the general mushiness of my aging keyboard. I first bought a G610 with cherry mx brown keys. I hated the key switches. There was about two millimeters of travel before anything happened. I felt the strokes I had to make to type were much longer than normal, and frankly the tactile bump just felt wrong. So I returned it and my search for a new keyboard continued.
I tried out a few other boards at a local blue and yellow electronics store. Cherry reds, blues, browns, some razer boards, and this, the k840 with romer G switches. It's hard to tell how things will feel at your desk by trying to type on the displays, but the romer switches seemed the most familiar. After waiting a while I ordered one because it was on a good sale.
Some people say the romer G are between red and brown switches, with a slight tactile bump near the top of the stroke. I agree. The lack of any bump on the red's felt strange. I wanted some 'buckling' point during the keystroke, and the brown's was all wrong. Some people say that romer G switches feel like rubber dome switches. I disagree. The difference is night and day. This thing feels great to type on. The keys are stable, you can tell when you've pressed them, there is no wobble or mush to be found. The only complaint is that there is sometimes a slight ringing sound when certain keys are pressed (mainly the 'i' key and the spacebar). You will only notice this in a quiet environment. I also find it odd there are no num lock or scroll lock lights, but let's be honest, when was the last time anyone actually used one of those keys?
The keys are pretty quiet for a mechanical keyboard. Another plus. I think the people that like the super loud clicky boards just like the noise, and that the noise does not do anything useful for the typing.
So, if you can get this thing on sale, go for it. If you're looking for something quality, but all the gamery rgb boards and super expensive custom keycap snob boards just don't do it for you, this is likely the keyboard you want. It is a sweet upgrade from ancient rubber dome board. This thing feels well made. It looks nice without shouting. I think logitech has engineered a great key switch that is actually useful for typing and gaming (I've tested both), and not just a gimmick or novelty. It is nice to find it in a not too expensive board.
- Reviewed in the United States on March 5, 20191 Year Later: Absolutely NO flaws. Getting another one for a second desk at work. Getting the 'gaming' model with RGB lighting for the house. The Romer switches are the perfect balance between feel and sound.
O. M. G. Got in my Logitech K840 keyboard today.
Absolutely brilliant key feel - anodized brushed aluminum key caps with laser etched letters. New Japanese mechanical switches. Just the right click to know you fired a key press, no louder that a rubber dome Lenovo keyboard. Slightly louder than the $5 Kensington ones they pass out at work.
But the finish, the quality of this board is an order of magnitude better than the price point. I have found the grail, antd it's is Logitech! Extraordinary price point - a full half less than even the cheapest 'gaming; keyboards without the LED gauche -- very clean and professional looking!
Please keep in mind, for 34 years I have typed exclusively on IBM Model M keyboards. I learned to type on an IBM Selectric. I learned to code on the OG a Apple mechanical keyboards. I have 10 IBM Model M keyboards in storage, just incase I ever break one. Literally a thousand year supply of Model M keyboards.
This Logiteck oustrips them all.
Works just fine on Macintosh, if you can remember the windows key is the Command key in Mac.
All I wish is it had a Kensignton lock slot on it; I guarantee if I leave this out at work while I'm on vacation it will get 'procured'. Now to find a case big enough to carry it back and forth to home.

- Reviewed in the United States on February 16, 2025it's good
- Reviewed in the United States on June 8, 2020Let me preface this review by saying that this is the first mechanical keyboard I have used, so I have nothing to compare it to. That said, this keyboard has made a fantastic first impression. PROS:
- This keyboard presents a very professional image. I am not a big fan of backlit keyboards. I prefer a subdued appearance, but I didn't want to sacrifice functionality to get it.
- Compared to the AmazonBasics keyboard that I had been using for the last four years, this keyboard is much more comfortable to type on. It requires significantly less pressure to activate each key, and the matte keys feel a lot better than glossy plastic ones. I'm a software development student who works in an office and plays PC games as a way to decompress, so I'm at a computer for roughly 14 hours a day. Every tiny increase in comfort is a big deal for me.
- It's nice to have shortcuts assigned to the F-keys. My old keyboard had these same shortcuts as standalone keys, and thus didn't require you to press the "fn" key to activate them. While standalone keys seem like they may be more convenient, it was always a pain to have to close out of Windows Media Player every time I accidentally hit the key.
- The keyboard feels like it was built to last. Though I've only had it for a day, I already feel like it's going to outlast my old keyboard.
CONS:
- This keyboard is pretty loud. Like I said before, I haven't ever used a mechanical keyboard, so I don't have anything to compare it to, but the sound meter app on my phone registers a pretty consistent 43 - 45 db when I place the microphone right next to the keyboard. On top of that, the Romer-G switches will not accept rubber o-rings like other mechanical keyboards, so dampening the sound seems out of reach for now (though I'm looking for workarounds). Additionally, there's a little bit of a "pinging" sound that comes from the springs within the switches. It doesn't bother me, but it might bother you.
- If you're used to using a low-profile keyboard, you may experience a bit of wrist pain at first. This keyboard is close to twice as tall as my last keyboard, and it has been a little rough to get used to. That said, this can easily be solved with some kind of wrist rest.
- There is only one tilt setting for the keyboard--you either have it completely flat, or at the predetermined tilt angle. To me, the tilt seems very inoffensive, but you may feel differently.
Overall, I think this is a great keyboard for the $59.99 sale price. I can say with confidence that this is the best keyboard I have ever used, but keep in mind that my experience is limited to built-in laptop keyboards, AmazonBasics keyboards, and cheap-o government keyboards filled with food crumbs.

David JohnsonReviewed in the United Kingdom on July 15, 20201.0 out of 5 stars Broke after 2 months!
Good keyboard, but it simply stopped working after 2 months of average use! Complete power failure, tried it in multiple USB ports and a different laptop. Very disappointing from what should be a high quality manufacturer. Have raised a ticket to get a replacement. To top it off - Logitech support response was 'these things happen' - no apology or explanation!
Scott WReviewed in Canada on April 24, 20185.0 out of 5 stars Great Keyboard, very happy with it.
This keyboard is very nice, very high quality and quite aesthetically pleasing. Coming from a membrane keyboard, it is quite noisy, but you get used to it quickly and the typing experience is much superior, making it worth the extra noise. Additionally, my typing style has changed with this keyboard, and I hit the keys slightly less hard now which makes them significantly quieter and is easier on the hands in the lung run.
Overall, if you're looking for a high quality mechanical keyboard that is a little more subtle than some of the vibrant RGB gaming keyboards out there, look to it, then this is the perfect choice for you.

BrianReviewed in Canada on September 19, 20175.0 out of 5 stars Wonderful substitute for Cherry MX browns
Just received this keyboard, and can't recommend it enough!
I've tried various mechanical keyboards in the past. Admittedly, all of my experience is with Cherry MX switches. As I do mostly programming and a bit of gaming, I tended to stray towards blues and browns for the tactile feedback. My daily-driver at home has Cherry MX browns. The lighter tactile feel was preferred over blues, until this keyboard.
I bought this to use at work, and I'm sure it will live up to the task. They keys feel great, and the Romer G switches remind me most of the cherry browns, with a slightly different tactile response reminiscent of dampener rings on the keys. I love the simplicity of this keyboard, and the keys being raised from the bed without an edge or bevel will make it super easy to keep clean. The metal surface and subdued color tones make this keyboard look super classy.
Pros:
- Great key feel
- Easy to clean deck
- Soft, yet noticable, tactile response on keypress with the Romer G switches
- Not super clacky
Cons:
- No scroll lock or num lock lights
Amazon CustomerReviewed in Canada on May 5, 20204.0 out of 5 stars Almost perfect!
I game, and work on the same system. I need a keyboard that needs to be nice for typing, and games. The Romer G switches are a great and feel good for both. The keyboard is very nice and classy looking. However, the lack of a num-key light is honestly driving me insane.
Christopher WooReviewed in Canada on June 24, 20203.0 out of 5 stars Decent for work, but not gaming
This is my first mechanical keyboard and since I bought it during the pandemic I was unable to test it in person. Overall it feels fine when typing, there is a nice tactile bump with each stroke that gives each press a great feel. The back-plate is metal which adds some weight and sturdiness to the whole board. Keys can be taken off and cleaned pretty easily but each key label is merely printed as a sticker. I can see this being a problem after prolonged usage. The non-RGB is great if you are looking for a more office style board and the USB wire is thick enough to not break under use.
This should not be used for gaming however. To me the keys feels just a tad too spread apart, I find myself reaching and missing some keys even when they are right next to each other. I don't play games that are too fast paced but even moderate FPS games will take some use to.
My biggest complaint is about the sound of key strokes. While the stroke itself is fine, the key being pressed into the back-plate produces an audible "ting" sound that reverberates through the metal. The harder the press the longer and louder the ting. If pressed hard enough the vibrations can be felt through the key. My board had these sounds out of the box and I assumed they would disappear with use but they remain even a month later. I've tried placing the board on foam and applying some minor oil but the ting remains. The next board I get I will remember to test it out first.
