    • Solid keyboard backed by even better customer service.
Color: Black
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. ... show more

    • Very good keyboard for your buck.
Color: White
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. ... show more

    • Decent keyboard for the price.
Color: White
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. ... show more
