Simply the best keyboard for its price. The quality, design and sound are absolutely amazing. After one month of often usage its still as new and hopefully it will go so on, the keyboard's backlight is very bright and holds the charge for a surprisingly long time. The material is super quality and overall for its price this keyboard is brilliant. Definitely recommend it - 10/10
Love the keyboard! Constructed of aluminum, very hefty (feels like someone gave a care when they designed it) And all the gaming keys you need. Great keyboard!!
I'll start with the cons because there are many.
1. I know there is a trick to do it but I want to disable that logo (I like my keyboard without any lighting. I kept the lights on for photo only). There is no easy way from the software
2. The software interface is built by a 10 year old gamer
3. The knob on top right is not customizable.
4. The key color makes it impossible to read the shift row without backlight.
5. It's hard to find key caps that go with this design, due to how different it is.
That being said, this keyboard still deserves this 5* because of how nice it is to type on. Sounds good, and feels good to type on. I know it's subjective but among all the keyboards I've used (including the crush 80), I like this one the best.
They also give you multiple single switch options which is quite nice because I don't like the stock spacebar sound. If you are like me, you get to switch to a thockier option or a lighter and less noisy one as spacebar is very different from rest of the keyboard.
Overall it's awesome! I don't miss the screen on my old keyboard but I wish the knob was customizable. Also I don't want the logo, I would have liked an extra customizable key instead.
I've been using the GravaStar Mercury K1 Keyboard, and it is a pretty decent board. The aluminum alloy exoskeleton design not only provides a sturdy build but also adds a unique aesthetic appeal. The gasket-mounted structure, combined with hot-swappable linear switches, offers a customizable and satisfying typing feel. Additionally, the vibrant RGB backlighting and frame illumination create an immersive gaming atmosphere.
In collaboration with Kailh, GravaStar designed custom 40gf linear switches with 1.5mm pre-travel, which deliver a smooth and responsive feel. Finally, the K1 features three modes of connectivity (Bluetooth 5.0, 2.4GHz, and USB Type-C) and an impressive 8,000mAh battery for extended use.
I did not enjoy GravaStar's proprietary software as I am used to boards of this price point support QMK/VIA/Vial.
Pros:
- Sturdy aluminum alloy exoskeleton design
- Gasket-mounted structure for enhanced typing comfort
- Hot-swappable linear switches for customization
- Vibrant RGB backlighting and frame illumination
Cons:
- Software is not open-source and lacks advanced key mapping functions
- Premium pricing may be a consideration for some users
Bought for grandson/ he loved it!
My son loves it - immediately swapped out his razer and was blown away. Great quality and very fast.
Love the clicking sound the keys make. Nice creamy keystrokes.
Makes a great lap keyboard from the sofa since I use my pc on my living room TV from across the room. The keyboard is flat on the bottom making it comfortable. The key lights are visible from the lap even though they are on the front of the keys. But you can buy bold letter stickers (like I did) to put on the top of the keys just in case.
I’ve custom built so many keyboards over the years and the way this thing is built puts it’s right there with or even above the ones I’ve built that are way more expensive than this gravastar. Design is amazing (the reason I bought it) but the sound and feel of each key being clicked is what really put this keyboard above and beyond other pre built ones. Whoever designed this, amazing job!
Nephew has no complaints really loved it and tested it out. He linked it with his Apple iPad aka Bluetooth. Keys light up! Connectivity Good 👍🏾. Loved pressing on the keys he was excited about that.
Update: it also connect to the main tv in the living room via Bluetooth you can type in the search bar from the keyboard if anyone’s interested 🤗
Beautiful colors, nice compatibility, good compatibility and connectivity, good value for your money, great keyboard feel, and sound quality.
I know this keyboard is really not everyone’s cup of tea, but it was mine. And I loved the build quality, while not 10/10 it’d still very strong, it sounds really amazing out of the box, and feels great to type on for my hands, if you love Sci-fi aesthetics, and want something that’s not tooo over the top with it, I think this is the best option from Gravastar.
Works great, sounds good!
By far the most satisfying keyboard I’ve ever used. Between the quality and the functionality you can’t go wrong. Not to mention how easy it is to customize. GravaStar is definitely the way to go. Extremely pleased.
I’ve been collecting keyboards for the past 3 years. This is by top one of my favorite keyboards as it has a great design and number pad.
Un teclado de fantasía
Great keyboard pricey so only get when on sale . Lots rgb options and keys sound great. I see people don’t like the logo to turn it off press function key with caps key. I think you need plug power in as I have the space bar sometime it don’t work on WiFi . Well you get a cool looking keyboard premium feeling
so happy thanks great servises
En uso desde el 1 Abril y tiene full batería a hoy 13 abril, es simplemente espectacular, ya tenía un Epomaker pero la verdad aunque es un poco más sonoro la sensación táctil y el tiempo de respuesta es espectacular, siempre fui fan de los teclado con carcasa en aluminio y este no es la excepción. El diseño es espectacular y se siente pesado, definitivamente la única razón por la que no le doy 5 estrellas es por su software, es de lo peorsito que he visto, una marca de este calibre sin lugar a dudas debería tener un mejor software
I’d never want to get another keyboard after this one
This keyboard is amazing. I can type up to 150 wpm, but I've killed a lot of keyboards. Finally decided to quit buying el cheapo and go with something that has guts and can withstand my typing.
Perfecto
Very nice even came with a nice decent length charging cord.
I doubt there’s a better option out there at this price point or even a slightly higher one. The sound 9/10 (space bar leaves a bit to be desired). Build quality 10/10. The lights cut off pretty fast when you’re not using it so the battery life is really good! Also, without the lights on it is so clean looking on the desk. 100% absolutely recommend this keyboard
Worth it
I don’t normally write reviews but I’m really specific about my hardware. This keyboard is amazing. It has the aluminum frame with a powder coated black finish that makes it sleek for my setup. It’s sturdy, just the right amount of heavy and high quality.
The lighting around the edges is a really nice touch. You can download the software from gravastars website but it doesn’t have controls for the lighting around those edges, just the back lighting of the keys themselves. The user manual does however tell you how to change the back lighting which makes up for it.
The volume knob on the upper right of this keyboard is also perfect minimal design. I love that it feels so easy to turn the volume up and down and if you press it down it mutes the audio. If you download the software from their website it allows you to easily setup more music options like what I did with the F10-F12 keys.
The keyboard is small so it doesn’t take up much desk space and truly is my all time favorite now that I’ve swapped the keys to some custom ones I got a while back.
Last thing, the clicks on the keyboard are not resistant at all so you get that creamy feel and sound. It’s not quite linear switches but It’s also not clicky. If you like quieter typing then you may want to swap the switches. My old keyboard had much quieter switches but I dont mind the swap.
If you were stuck on this board or another for an easy custom keyboard, do it now. This keyboard is so much better than any EPOMAKER or AULA or any keychron in my opinion. The price is also perfect for this type of board. There’s literally no better option.
ONLY down side is no numpad but since the board is for gamers I understand why. I’ll just get a separate numpad later if I really feel that I need one.
