CB-GK-16 Firefly TKL Mechanical Gaming Keyboard | Per-Key RGB | 3 PIN Swappable Outemu Blue Switches | Upgraded with Detachable USB-C Port | Macro & Software Support (Black)

The Cosmic Byte Firefly CB-GK-37 is a great budget mechanical keyboard if you want eye-catching RGB, a solid compact build, and decent performance for gaming or typing at its price point. That said, its software and long-term reliability can be hit-or-miss — so it’s best for budget-minded buyers or first-time mechanical keyboard users rather than pros demanding long-term durability.

Really impressed with the build and typing experience. The keys feel tactile and responsive, with a satisfying click that’s not too loud. The backlighting looks nice and adds to the overall look, especially at night. I’ve used it for both gaming and work, and it performs well in both cases. Feels durable and well-built. If you’re looking for a good mechanical keyboard without spending too much, this is a solid choice.

The Cosmic Byte Firefly is a very good keyboard indeed. Pros- *Build quality- It is a very solid and well built device with the top part in steel and the bottom part in plastic. It is pretty heavy but it is a mechanical keyboard so no surprises there. *Accuracy- The keyboard is very accurate for typing. *RGB-RGB is definitely very good. It has a selection of many single colors and mixed ones too. *Hot-swappable keys- The keyboard has hot swappable keys which means that the switch itself can be replaced with other Outemu switches. I'm not sure if other brands switches can be used. Cons- *Typing sound- If you are going to buy this keyboard and type a lot, do not buy the blue switch version. I really underestimated the sounds of the blue switch. It sounds like an actual typewriter. It is pretty much annoying as it is making too much noise. The red switch version can be better if you type a lot as it is more quiet. Also, other people may find it disturbing. So buy blue switches only if you have a separate room. *Dedicated Caps lock indicator-It actually does Caps lock and scroll lock indicators in the keys itself, but it is not visible if the RGB color is white as the indicator colors are also white which can be confusing. So I would suggest Cosmic Byte to put dedicated Caps lock and Scroll lock indicators. *Portability- The keyboard is huge and heavy which makes it pretty hard to carry it around. The packaging they sent the keyboard in was very good. It came in a cardboard box inside a sealed bag. Overall a very good keyboard for 2000-2500₹.

Very smooth operation... Red switches aren't that clicky... If you want clicky sound just go for the blue ones... No bluetooth support... But does the work well... Good build quality... Metal frame and with sturdy base... An overall good product... I bought at around 2k...

Really good for the price. I could have gotten the Zebronics wireless one at this price but went with this because of the space in between each keys. Also this comes with two additional red switches.

1) Pls note that the packaging of the product is significantly improved and it no more comes with a bad packaging (which was the case in 2020!). The product I recieved was in a neat and sturdy packaging. It was nicely covered with a box that had zero damage and the box was also contained in a bigger container(double box protection! Rest assured about the packaging, it was an issue in the past. 2) If you are coming from a membrane keyboard then the quality or build of the keyboard will definitely be a premium one for you. It has got quite a weight to it and hence feels quite a good built. But the braided cable feels a bit cheaper COMPARED TO OTHER BRAIDED CABLES. It is still good compared to normal rubber cables. 3) The keys are simply awesome. You will definitely get obsessed by typing on this keyboard. It simply feels great to type on it. The keys are quite loud and fully give the mechanical keyboard wala vibe that you need. I got so customed to this board that when i returned to my laptop keyboard it felt like its keys were inaudible(not kidding!). 4) Though rgb was not my first priority while buying this board.... but it too is just simply great! The colors are surprisingly vibrant and bright enough for most of us users. There are enough modes that one might need and you can even change the brightness of the rgb. If you need any more custom modes (if you are that much of a psycho xD) you can get it done through the CB software that the keyboard supports! 5) As mentioned RGB was not my first priority. I needed a compact ten key less mechanical keyboard which i needed for my college work and mostly for CODING! And .......... i am in love with this keyboard. The form factor is really very compact and it does not take much space from my desk and i can keep my board and write on my notebooks at the same time without any difficulty (which was one with my previous keyboard. I always needed to switch my keyboard and notebook from the desk very often and it irritated me alot). 6) One thing that i encountered was that my typing speed reduced while typing on this keyboard. I also made more errors while coding using this. I tend to mispress quite often and this is due to some anti ghosting keys that this board has. But its not quite that big of an issue and I will get accustomed to it with time imo! So, my final thoughts for buying the board would be that - if its your first mechanical keyboard .... JUST GO FOR IT. You wont be disappointed by the product. And if its not your first then too you wont notice any significant issues with the board and it will be just simply great for most of us!

1. The keys feel sick now, I have to double press some and some are harder to press. 2. The numerical keys no longer turn on RGBs. I work at night so a big issue for me. 3. Some keys are showing different color for some reason. I miss older keyboards that used to last for decades :(

I’ve been using the Cosmic Byte Firefly CB-GK-16 (Blue switch variant) for about 2 months now. Honestly, I didn’t expect this level of quality for the price. The build feels sturdy, with a metal top plate that gives it some good weight doesn’t slide around. The switches are Outemu Blues, so yeah, they’re clicky and loud. If you’re into that tactile typing feel, you’ll love it. Typing feels satisfying, and key response is crisp. Definitely not silent though, so maybe not the best for shared rooms or late-night use unless your roommates are cool with it. The RGB lighting is bright and clean. Tons of modes to cycle through using the keyboard shortcuts, even if the software isn't the most polished. It’s tenkeyless, which is perfect for my setup. Saves space without sacrificing comfort or usability. I use it for both work and gaming (Valorant, Apex), and it holds up really well. Nothing has gone wrong till this day Couple of small things: The keycaps are decent, but don’t expect premium material. They're fine for daily use though. Blue switches are loud not a downside for me, but something to be aware of.
