RK87 Sink87G RGB 80% Mechanical Keyboard, Wireless 2.4G Tenkeyless Mechanical Keyboard with Programmable Software, 87 Keys, Tactile Brown Switches | 87 Keys Wireless 2.4G Tenkeyless Gaming Keyboard with Programmable Software, No Numbpad Compact Wireless Keyboard

I purchased the RK ROYAL KLUDGE RK87 Sink87G RGB in January 2025 and was genuinely impressed right out of the box. The build quality felt solid, the typing experience was smooth and responsive, and the keyboard back lighting was customizable and vibrant without being over-the-top (even though I only use white). At this price point, it honestly felt like a great value — better than some more expensive boards I have used. Over the next couple of months, though, I started noticing some minor issues — a keystroke would occasionally not register, or it would double-type. It wasn’t consistent, and at first, I figured it might just be me. But the issue slowly became more frequent, and eventually, I knew something was off. I decided to contact Royal Kludge support — not expecting much, to be honest. Maybe a canned response, or a small discount toward a future purchase. What I got instead totally surprised me. Their customer service team was incredibly responsive and genuinely helpful. They didn’t just go through the motions — they took the time to listen to what I had already tried and then offered new, detailed troubleshooting steps that showed they actually understood the product and cared about solving the issue. When that didn’t fix it, I reached back out — and the very next day, they had a replacement unit in the mail to me. No hassle, no arguments, just a clear commitment to standing behind their product. In short: the keyboard itself is great — well-built, stylish, and enjoyable to use. But what really sets Royal Kludge apart is their after-sale support. It's rare these days to find a company that doesn't just make good hardware, but also supports it so well after the sale. That kind of experience builds trust, and it's why I’ll definitely be buying from them again. If you’re on the fence about trying one of their products, I can say from experience: not only are they worth it — you’ll be taken care of if something goes wrong.

Update: After almost a full year the keyboard is still performing like new for me. I've only needed to plug it in to charge maybe once a month, all the keys are perfectly responsive, all colors illuminate on all keys, and I can find nothing to complain about. Indeed, I'm not sure whether it's because I've acclimated to the feel of this keyboard or because the switches are getting broken in, but I find typing on this keyboard effortless and highly enjoyable. I suspect the people complaining about bad battery life are overcharging. I never leave mine plugged longer than overnight. Original review: This keyboard's Outemu Brown switches produce a more obvious tactile bump than the Cherry MX Browns on my Das Keyboard at work, and so require slightly more pressure to activate. That's not to say these aren't still light touch keys, though. I can still type on them at a normal speaking tempo without bottoming out on my keystrokes. They require noticeably less force to actuate than my wife's Cherry MX Speed Silvers on her Corsair K70. At the moment, these Outemus make the tactile bump in the Cherry MX Browns at work feel almost accidental by comparison (which I've always experienced as more of a vague scrape than a tactile bump anyway). We'll see whether that's still true after a couple months' break-in. (Edit: After 3 months, the tactile bump is still significantly more pronounced on the Outemu Browns than on Cherry MX Browns. Edit 2: After 7 months, the tactile bump is still plainly present, although it never draws my attention unless I'm actively considering it.) The lighting effects in this keyboard are trippy. You can cycle through lighting modes and record macros using key combinations, but the software downloadable from the rkgaming website makes customizing easier. When you go to download the software, DO NOT use Google Translate, and do not click the English flag. The file host's download link will not appear on Google's translation. Just Ctrl+F and search for 键盘驱动 on the rkgaming home page, then find Sink87G on the resulting page. That takes you where you need to be. This keyboard seems well-assembled. There are no dead LEDs, none of the stabilizers seem misaligned, and all of the keys are responsive. Using the ripple lighting effect, battery capacity is plenty. I've had this keyboard on a single charge for about a month so far with usually around 1 - 4 hours per day of use. I had to send my first keyboard back as defective, but Amazon's generous return policy and Prime shipping ensured I eventually got a working keyboard. Just bear in mind at this price, you might have to play a bit of quality control. Just be patient, and you'll end up with a nice mech keyboard for 1/3 or 1/4 the cost of more boutique keyboards at similar quality. Pictured is the RK Sink87G with the Logitech N600 lapboard .

Features: Outemu Brown mechanical switches, NKRO, 2.4GHz wireless, "16.8m" color RGB (courtesy of several lighting effects). What it gets right: * Outemu Brown switches actually feel pretty decent. A connoisseur will know and feel the difference between Cherry MX browns and these, but most people won't notice- much less actually be bothered. * 2.4 GHz with a dedicated USB receiver. I play Apex Legends (Diamond), Rocket League (Champion II), and other games that are highly sensitive to input latency, and thus far have not noticed any additional latency versus my Logitech G810. * USB-C connector for charging. Kinda meh: * Battery life isn't bad, but it's not really impressive either. For a mechanical board with NKRO and RGB lighting, it's about what I'd expect (4 hours with RGB lights enabled and on brightest settings). * Power switch is on the back of the board, instead of on a side or front. Annoying but not a deal breaker. * The included USB-C cable isn't anything to write home about. The bad: * The battery charge indicator is on the left of the spacebar's key switch and only lights up when the board is not yet fully charged or is literally about to die. It's red and not very bright, making it hard to see even when looking at the keyboard. You will not notice it if the battery indicator comes on while you're gaming, and it only comes on when the board is within minutes of shutting off. This board has shut off on me a few times during gaming sessions. * Caps lock indicator, and one other LED indicator on the board are white only. I have no idea what the other LED indicator is for. * This board pings like a muppet. Not sure if it's the empty space between the PCB and the back plate, the backplate and the casing, or something else, but it is metallic and loud. It's especially noticeable with the larger keys (1.5u and larger). If you don't game with a headset, you will notice this out of the box. * RK's app is the purest form of hot garbage, and doesn't even open when I attempt to use it on my primary gaming rig. Overall, I feel it's worth $55. This board performs as expected or better, with its drawbacks mostly only being annoying. The fact that it's mechanical, wireless, TKL, and has RGB lighting far outweighs the issue with the board's charge indicator being nearly imperceptible.

The RK 87 Wireless TKL keyboard is fantastic! The wireless connection is rock solid with no noticeable lag, making it perfect for both gaming and work. The mechanical switches feel great—responsive, tactile, and satisfying to type on. The RGB lighting is vibrant and fully customizable, adding a nice aesthetic to my setup. I also love the compact TKL design, which saves desk space while still providing all the essential keys. Battery life is impressive, lasting for days on a single charge. Overall, this keyboard delivers excellent performance, build quality, and features at a great price. Highly recommend it for gamers and professionals alike!

I have never used a mechanical keyboard before this, only mechanical "feel" membrane keyboards. This one was one of the cheapest wireless ones I could find, cheaper than a lot of the wired ones even. I was immediately impressed with the heft of the material and how responsive the keys felt. Pleasantly surprised to see a lot of interesting backlighting modes! I was not buying this for fancy rbg so when I saw that it has lots of different modes that follow your presses, change colors, etc, it was a fun touch. There's only two things I would criticize this keyboard for so far is that the battery goes kinda quick (have to charge it at least every 2 days when I'm using my computer a lot) and doesn't show you when the battery is low until it starts to effect typing. It flashes right when the battery is about to die, but there's no way to tell before that. The other thing is minor, but I frequently pull my keys to clean under them and have noticed a little bit of cracking on the bottoms of the small keys after about 2 months. The keys aren't broken and they're still very useable, but that probably tells you something about longevity if you also frequently clean your keyboards.

I’d like to say that I’ve had the steel series apex pro keyboard. Two years the the keys began to stop working. Now it’s unusable. I had just bought another wireless keyboard and mouse by Logitech a month ago and it lost its signal constantly. Even at two feet away. Horrible. This is great so far. Tip If P key flashes it’s Bluetooth Also when it dies in wireless. It dies suddenly. *If you add wire. You MUST turn IT OVER and turn it to OFF. OR IT STILL WONT WORK. I also just realized I can add the Bluetooth dongle to the end of a usb extender and it’s closer to me:) maybe that helps also It is constructed well. And going from wired to wireless is not terrible hard when you figure out that you have to sometimes switch the back to wired or wireless and then hit special keys. Very happy to be able to go from wired to wireless. The ONLY problem I have is that the wire that goes into it has issues staying plugged in the port. It’s nice to come out with its pulled too much but it’s so loose. It comes out far too often and feels loose. A magnetic port would have been great.

The keyboard is heavier than I thought it would be. I’m used to the Logitech natural. I really like the feel and have noticed more accurate typing due to the better feedback on my fingers. The heft of the keyboard keeps it from sliding around too, something I appreciate. I do t use the LED light but maybe some would find it neat? It’s a nice keyboard and a good value. The brown switch is a tad heavier than red switches which I prefer because I don’t play computer games anymore. This was a work purchase and it really made my day. The compact size allows me to keep my mouse closer to my body for efficient work. The sound level is probably higher than I expected but it’s not too bad. If you are a heavy typist, you will be heard on Zoom calls. Having learned on a mechanical typewriter, this surely is my downfall. Bottom line: it’s a great purchase. Worth it. 100%

Have had no issues so far, great quality nice lighting, and the app is easy to use not very heavy but heavy enough you can tell it's good quality

Era para mí novio y le ha encantado! Los Brown switches le encantan y es de los pocos que encontré en Amazon ES que es qwerty 80% y con ese tipo de teclas

Nachdem ich nun einige Tastaturen getestet habe kann ich sagen das diese RK wireless RGB Tastatur absolut empfehlenswert ist! Preis Leistung ist absolut angemessen, gerade weil der Markt bei wireless Tastaturen MIT Beleuchtung/RGB äußerst rar bestückt ist (leider). Diese erfüllt aber alle Kriterien super. Die Beleuchtung ist wirklich richtiges RGB, welches sich mit Tastenkombis ändern lässt. Auch ist die Beleuchtung nicht zu hell oder dunkel, auch dank der mehrstufigen Intensität, so daß man alles sieht und trotzdem nicht geblendet wird. Die Verarbeitung ist wirklich erstklassig, nix wackelt oder ist schief und der Kunststoff schaut auch hochwertig aus. Daher wundert es auch nicht das diese kompakte TKL Tastatur "erschreckend" schwer ist. Die braunen Switches (ich vermute es sind kailh) sind top und hinterlassen ein super Tippgefühl und sind zugleich LEISE und haben trotzdem einen gut spürbaren Druckpunkt. Die Wirelessverbindung ist bisher ohne Beanstandung und funktioniert auch ohne Probleme im BIOS (USB 2.0 Dongle). Es gab bisher auch keine Probleme mit Verzögerung oder Ungenauigkeit im Punkt gaming. Der Akku ist zudem auch recht schnell geladen (entweder jedes 5V USB Handyladegerät, oder über USB Anschluß am PC) und hat bei mir mit Beleuchtung bisher knapp 16h am Stück gehalten. Was zu erwähnen wäre ist, daß die Tastatur schnellladefähig ist, entweder Quick Charge fahiges Netzteil, oder über den USB 3 Anschluss am PC. Dieses wird aber nicht in der BDA(ja die gibt es Tatsache in Papierformat dabei, genauso wie ein keycap Werkzeug) erwähnt. USB 2/standard Netzteil ~3h, USB 3 oder Quick Charge ~30min-1h. Auch die Energiesparfuntionen, bzw. Standbybetrieb ist erwähnenswert, da sleep und awake ohne Probleme funktioniert und sollte der PC aus sein, also keine Verbindung zum Dongle bestehen, schaltet sich die Tastatur auch ab und lässt sich nur einschalten (RGB Beleuchtung funktioniert) wenn das Ladekabel angeschlossen ist. Das USB C Kabel dient auch wirklich nur zum Laden, wenn der dongle zeitgleich installiert ist. Die Verbindung mit dem PC ist dann nur wireless, ohne dongle geht es auch nur mit dem Kabel. Das einzige Manko, was eigentlich keins ist, ist die Tatsache das ich bisher nur US/ENG QWERTY Layouts finden konnte und leider kein deutsches mit ÄÖÜ. Daher ist hier die Einschränkung das der Nutzer schon Erfahrung haben sollte und wissen wo die Tasten sind, außer man bevorzugt das US Layout. Und was Gewöhnungsbedurftig ist, der on/off Schalter ist unter der Tastatur und super mini. Also ich kann die Tastatur jedem empfehlen der wireless RGB möchte, aber nicht 100€ für corsair oder gar 200€ für logitech (g915 lightspeed, welche echt erstklassig ist!) ausgeben mag/kann. Klar kann man sich passende Keycaps kaufen, dann ist man aber meist auch schon in einem preisbereich von über 100€.

This is my first foray into mechanical keyboards. I have been using normal cheap keyboards for years. I am I software developer so do a fair amount of typing. I love working on this keyboard. It can be a bit noisy even with the 'less noisy' brown switches. As someone that sits in front of a keyboard for hours a day, I would def recommend this keyboard. Its happiness for your fingers! It is backlit and I like that it is wireless. I don't like wires on my desk. It charges via usb3 while using it so when it goes flat you can still use it. Battery life is fair. Furthermore, I enjoy tinkering with electronics and managed to clear the firmware. I reached out to RK and there support was helpful and friendly and got my keyboard back up running. That is pretty good service I think as it was completely my fault. Would def recommend just based on the support I received.

Buona tastiera meccanica per chi vuole una postazione senza fili, fa il suo lavoro egregiamente. L'unica pecca la batteria non è il massimo.

Au top!
