very nice mechanical keyboard that's not overly expensive with amazing rgb features
I've been using the RK Sink87G for a few years now and it's been great. The wireless feature with the built-in battery and USB dongle works really well, and the RGB lighting looks awesome there’s per-key lighting and lots of effects to choose from. I'm using the brown switches and they feel really nice to type on. The keycaps have held up very well no visible wear even after heavy use, so the build quality is definitely solid. Overall, it’s a great keyboard, especially for the price.

Great keyboard
Have had this keyboard for nearly a year now. Nothing bad to say about it, all keys responsive with a nice feel to them. Lighting and battery life is also very strong. Highly recommended

Really good keyboard, for the price.
The only negatives to consider is that RARELY the signal messes up and might spell out a letter once or twice more than what you actually did, but as I I mentioned it is a very rare occassion. The second negative is that if the RGB is on the battery does run out pretty fast compared to if you dont use the RGB at all. Other than that it sounds good, the lighting looks clean and the design is very nice.

Excellent keyboard with a good price
Overall, the keyboard is good at this price. Its build is not supper but good, wireless makes the table much tidier. It is hard to find a wireless mechanical brown switch keyboard at this price. Typing feels and the sounds are nice (brown switch - a little hard but not too hard, none clicky). The led is not too bright but it is acceptable, there are many patterns to choose from RGB to a single color. The battery is not too great but acceptable too. TKL layout is good for different purposes. I use this for my coding and gaming. There are Fx keys for coding and the layout is pretty much the same as a full size.

Charge is awful, but ok keyboard
OK keyboard in general but battery is awful on it! Lasts 2 hours before needing to be charged, although it never shows the charging bar full either! Echoes when you use it too (not an issue for me personally but might be for others) US layout too, but you get used to it. Dont think its worth the money spent on it though, would have been better off paying less for a wired keyboard

Lovely Keyboard - Great Customer Service
Had the keyboard for over a year and love it, I did lose my wireless dongle so I can only use it wired, but I still enjoy it. Unfortunately my keyboard's colours changed and I wanted to change them back, but I think the firmware bugged out and the keyboard became bricked. As the keyboard was out of warranty, I couldn't get a replacement so I contacted RK customer service and after a few days (mainly due to my work commitments) they sent me the firmware fix and Lia was incredibly helpful throughout. I double clicked the firmware .exe and after 3-4 seconds my keyboard was working again. Massive sigh of relief and I get to keep using my favourite keyboard. Lia if you read this, thanks again!

The @ and " are programmed in the right places but the symbols are switched.
Great keyboard but i've noticed one small thing, the @ symbol is in the wrong place its on the 2 key and the " is where the @ should be but the " is still programmed to be the @ and the @ is still programmed to be the ". Apart from that its a great keyboard...

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

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.
