Review: Great product - 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.
Review: Review as of May 2021! PACKAGING, BUILT, KEYS, RGB, CODING EXPERIENCE, ISSUES, FINAL THOUGHTS .. - 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!

### ⭐⭐⭐⭐⭐ bang for the buck
*by Y***I on 12 April 2025*

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.
