RK87 Sink87G RGB 80% Mechanical Keyboard, Wireless 2.4G Tenkeyless Mechanical Keyboard with Programmable Software, 87 Keys, Tactile Brown Switches

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.

Did I need a keyboard? No. Did I want a keyboard to put custom kittypaw keycaps on? YES. This keyboard is easy to customize, but because not everyone wants to waste their money on keycaps I will say that his keyboard is worth it for the quality alone. It's heavyweight, giving it a sturdy, well-made feel when you type with it. It doesn't slide around my desk like my old keyboard did, and I really like that it stays put. I connect it via bluetooth, and I have not noticed any issues with it disconnecting randomly. I don't notice any lag when using this keyboard at all. I also found that I could replace my keycaps and switches very easily and the custom caps fit well. The backlight took some getting use to. I barely use the backlight function, as I usually type in well lit rooms. You can set it to one color, or rainbow, and it has different lighting effects too. I think this keyboard will be a good upgrade for a beginner keycap hobbyist, or for anyone who likes a sturdy, quality keyboard for a good price.

What to say, I like the lights, lol. There are a bunch of different colors and patters and I like how they can be accessed via key combos instead of needing software. The lights auto turn off a little bit after typing, which is to be expected with a wireless device. The typing feel is pretty nice. The battery life is decent, lasts for days with casual daily use. It is pretty sturdy and well made. The keyboard was plug and play and of course easy to use. I'm not sure that I prefer rechargeable keyboards (or mice). When you do run out of battery you are left tethered again and probably leave the cable just sitting there still plugged in for the next time it is needed. I feel like the range for wireless connectivity is a bit short for my preference but typical for a wireless keyboard. The ten key less format is great for saving space, if you don't need that number pad. I will take off one star because the keyboard cannot be used with just the cable, it only communicates/works/types through the usb dongle. While this is typical of rechargeable wireless keyboards, it isn't ideal.

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 .

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!

With my first keyboard being one of the ancient IBM mechanical keyboards that were handed down to me as a kid, this definitely has a similar feel and sound as I type this. I order this with the brown switches. If you're expecting this to be used for portability, it is technically small enough to lug around. However any mechanical keyboard you buy is going to be heavy! This keyboard is no exception and it probably isn't something you want to take to use in public places like Starbucks. That sound of CLACK CLACK CLACK CLACK as you type will most definitely annoy the people sitting around you! So far I've used this keyboard for 4 hours on the charge that it had out of the box and my first impressions of using this keyboard are just filled with childhood nostalgia! The keyboard is very responsive. Even after switching from a drastically different keyboard, I'm still pounding out between 60 - 70 words per minute casually without seeing any slow down. The layout feels a bit more compact from the prior keyboard I was rocking for the past 3 months, this makes key travel the only learning curve that I've been fighting for the past few hours, but it's a standard layout without much deviation. So switching to this keyboard, it should become comfortable to begin using within 30 minute or so. I really like that it has the arrow keys and system keys for insert, delete, home, page up/down, print screen, scroll lock, and so on. This makes the key still useful for working in DevOps doing System Administration tasks in Linux and programming. It's a fair compromise for keeping it portable while maintaining as much functionality as possible. The lights... they have a reasonable amount of mode selections. I believe there are many people that will appreciate this, however I don't care for back lighting. To me it doesn't really serve a purpose, but if the RGB lights matter to you, you'll probably like the built-in modes available. Considering that, I don't know how moddable the RGB lights are. Action keys - those keys you have to hold the FN key to use. I primarily use the volume keys and having them available on this keyboard is great. Now... I feel these volume keys are in the wrong order, but having them at all is better than not. There is also a key to open up "My Computer" and the "Calulator" app which is extremely useful to me. They also crammed the context menu key into the board, which is something I use regularly. -------------------------------------- To sum everything up (TLDR): My initial first experiences with this keyboard are extremely positive. They managed to make a reasonably "portable" mechanical keyboard that retains tons of functionality I need for daily tasks. I will be following up at a later date to update this with further thoughts on battery life and any issues I come across. -------------------------------------- Update (1 week later) - Battery Life: I've found it very hard to pinpoint what the battery life is for this keyboard as "new". After using it as my primary driver for the last week, it's taken a couple of days for me to really discharge it to death. Pretty much amounts of time I don't want to track. When the battery was dead, I was super happy to find out that this keyboard supports input over the USB-C cable that came with it! This means that if the battery ever gets to an unchargeable state (which will happen some day), you can still use this keyboard while wired. -------------------------------------- Update (5 months later) - Knocking this down to 3 stars. As of now I've had this keyboard for over 5 months and I've stopped using this as a daily driver after running into a two pronged problem. As of about 2 months ago, the battery failed to hold a charge for longer than an hour of continuous use. Prior it would hold a charge for significantly longer. There's no reason for a LiON battery's ability to hold a charge to dwindle like I experienced. However that would have been fine had I not ran into a 2nd problem. About a month ago I've found that the keyboard would not work upon a reboot of my PC. I was using it hardwired with the USB cable that came with the keyboard. This shouldn't be a thing. After some troubleshooting, I've determined that it was only having this problem when the keyboard's battery was completely dead upon PC boot. With the main selling point of this keyboard being that it is wireless, having the core component of it (the battery) going significantly bad in less than a year is a big problem.

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

This is unquestionably the best keyboard I could have ever bought. I was able to easily replace the keys with custom keycaps and have not had an issue. The clicks are soft and satisfying. It connects without issue to my computer. I think it’s sleek, pretty, and easy to set up. I love the custom light colors (I set mine to green because I have green keys) The wireless function is excellent too (the keyboard just tends to double type if it’s low on battery). I have used this keyboard every single weekday for 1.5 years now and it’s as snappy as the day I got it. I really love it, and if you want a customizable keyboard that will last constant use, this is it.

Clavier mécanique de bonne qualité avec un clic satisfaisant et pour moi qui ne suit pas un hardcore gamer. Le sans fil (dongle 2.4ghz) est top et si vous voulez plus de perf l'usb type c vous assure une super Connexion /!\ ma version est QWERTY d'ou les 3 étoiles mais personnellement ce n'est pas grave car j'ai une bonne mémoire digital

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

Bonne qualité mais produit uniquement en QWERTY

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.
