Review: For the price, this one's a winner - For context, I'm not an RK fangirl, and have had honestly pretty bad experiences with their keyboards in the past. I bought this keyboard a couple of weeks ago closer to when it came out. I mostly bought this keyboard to replace an aging Keychron K2, and decided to take a plunge with this one because I liked the keycaps and design of this keyboard, and I was a specifically looking for a keyboard that had side printed legends that matched the firmware. I've been around the custom keyboard block and I'm sick of having to memorize key combos for system functions, changing rgb, etc. Guess I'm getting older lmao. I bought the version with the brown switches. Upon inspection these appear to be Outemu browns with the RK branding on them. They were surprisingly okay. The tactility was a bit better than gateron browns. They're perfectly fine, but the appeal of hotswap is being able to change the switches. I changed mine to Akko Lavender switches, which went completely fine. No issues in the keycap or switch pulling process I can't confirm the keycap material anywhere, but if I had to guess, they're a high quality ABS instead of PBT. Double shot, as can be seen from the pictures. The casting isn't the best when looked at from the bottom, but I'll never see it and it doesn't affect the weighting of the keys. The color scheme is gorgeous to me. And there's still a good thock sound because I know us keyboard nerds care about that. Stabilizers are pretty good. They're not screw in as far as I can tell. They're very solid though and there's no rattle. The switch mounting plate was what surprised me the most. It appears to be some kind of polycarbonate with slats cut into it. It definitely adds to a slightly softer typing feel and better sound. I used to think this kind of mounting plate was a bit silly, but I'm quite pleased with this one. The RGB gets pretty bright. Pattern variety and color variety is about average, but the lighting quality itself is good. I didn't try any of the software that RK makes for their keyboard with this. I honestly loathe installing software for peripherals unless there's macros I need, and the RK software in the past had given me some issues with the RK61 I had. If you care about the lift up feet, they're really solid on this keyboard. Borderline actually hard to flip in and out. I'm expecting those to stay solid for a long time. The knob and OLED screen. Oh boy these are actually really good. To turn the keyboard on and off, just hold the knob down. Rotate the knob to change the volume on whatever device it's connected to. Press the knob to open a list of connection options (wired, 2.4ghz, BT). To re-pair bluetooth just hold the knob down when the cursor is over one of the BT options. If you change between mac and windows mode, the keyboard will remember which OS mode it was in for each connection option, which is excellent for switching between a Windows PC, a work Mac, and my iPad. Btw, mac mode does swap the function and media keys from windows mode, so you have to use fn to access the function keys. This is pretty normal mac behavior on other keyboards (nuphy, keychron, etc). Just something to be aware about. The OLED display is informative and shows connection, OS mode, battery life. Battery life is pretty good. Got about a week to ten days of wireless with RGB at full brightness on the waterfall pattern. I'd imagine I could get a month with the RGB off. Gaming latency is fine. Feels similar to an RK61 on all three connection modes. The wired mode is fast enough for FPS games, but if you're really sweaty I'd start looking into keyboards designed specifically for low latency gaming. The wireless 2.4ghz is fast enough for casual games, but not competitive FPS games at all. BT is too slow for gaming, as expected. Overall, I'd recommend this keyboard. I got it at the launch discount with a coupon, which was an excellent price. At its current MSRP, I'd say it's pretty good. There's a lot of quality of life features and things keyboard nerds care about. There's a lot of features on here that you'd really only find on more expensive boards and custom boards. The OLED screen and knob are pretty unique and the biggest selling point for this board imo, but the overall design and color is what's keeping me around. Also it thocks.
Review: Fantastic Keyboard for Gaming/General Use - I've had this keyboard since September and wanted to really put it through some paces before a review. (Might be long, but i've had this for some time and wanted to give a good breakdown of this product coming from someone who has bought a few mechanical keyboards). Just a quick background, I play a large selection of games from Counter Strike, World of Warcraft, and other games between them. I'm also learning coding so I have used this keyboard for quite a bit of typing and long hours of typing so comfort is key. The Royal Kludge has been a game changer. I've been bouncing around different mainstream companies for a while now. I've owned 2-3 different Razer mechanical keyboards, 2 Corsair, and 1 Logitech. Nothing has been able to beat this. I've swapped out to my older keyboards from time to time to see if I 'truly' felt a difference. I always came back to the Royal Kludge. The pros. While these are mostly personal. Brown switches are a game changer for me. I love the feel and over the last few months, haven't had a single issue with any key or switch. The weight is perfect, while this is a little more on the heavier side, it feels sturdy and well built. The built in screen is really nice. Long time ago I had wireless keyboards and you would get a LED with Red, Green, and Yellow indicator. Hitting red felt like you were racing time. With the screen, you know exactly what you have left in the tank. Gaming with this keyboard has been really nice. I bought a 50% layout keyboard awhile back and while it was nice having a smaller keyboard on the desk, I really missed having F keys and some basic keys like Home, Page up, and Page Down. The Royal Kludge comes in clutch, it's the perfect size without giving too much up. The Cons. As I write this a few months after. I can't honestly think of a drawn out list of what I hate. The only thing I would of liked to see was backlit keys symbols. While the keyboard is backlit, the actual letters and numbers aren't backlit at all. While this isn't a complete show-stopper, it's something to consider when you buy it. Granted you can just buy a keycap set of whatever you choose later on to fix this. A minor issue, depends on the person. This keyboard does sit a little higher up. I bought a 75% Keyboard sized wrist rest, just to add to some comfort. I can't blame Royal Kludge for this with how much is packed inside. But as a reviewer to possible future owner. Maybe look into a wrist rest if you're feeling the height is a little harsh, it's night and day for me. Lastly while the packaging and everything was very good at protecting the keyboard. I wish the product came with a card of just a simple 'how to pair Bluetooth' or a breakdown of the settings. It's weird that a keyboard needs that, but since this one has a built in screen. I had to scratch my head a little when trying to pair it to a iPad because I couldn't figure out how to get it to start sending out a signal for pairing. After fiddling with it, I figured it out. But a card/little book would be nice. Once again, not a total show stopper since the desertcart page includes this information. tl;dr. Great keyboard, the cost gives you a solid mechanical keyboard without going into the 'hobbyist' side of it, great for FPS, MMORPGS, Coding, and general typing/use. No backlit key symbols on the caps, easily fixable though (buy new caps), and solid build. No manufacturing cutting corners it seems.

### ⭐⭐⭐⭐⭐ Impressive!
*by S***N on June 23, 2023*

I have used Hexagear Supernova with a brown switch for a couple of years. A friend sent me a gift card and this was in the right price range for it. It looks great on the listing and the functionality, especially switching between devices with the knob, was a big attraction for me. It was shipped from CA and delayed for a day. When I opened the package, I was surprised by the build quality. The base is plastic, which was a bummer for me. But, the plastic they used seems to be of high quality. Most of all, the brown switch they used... It feels really good. It is tactile, but a different kind of touch. I think Supernova has Gaetron switch. Whatever switch they used, this keyboard feels really good. I have used IBM5550 keyboard decades ago. This switch reminds me of the similar touch. And the knob functionality did not disappoint me. I have two laptops that are connected through BT and I can switch between the two seamlessly. I cannot tell much about the battery life yet because it's been only 3 days. I fully recharged the battery on day 1. I use my computers all day from 10 AM to 1AM next day. The charge at this time shows 96% through the little cute LCD screen. There are many RGB options. Because SuperNova has many RGB functions, I was not much impressed by or care about the lighting options. But, they are nice. I use "lighting-by-touch" option. In the future, I would like to try the Cherry MX Brown switch on this keyboard through hot swapping. But, I am not sure if I will get tired of the preinstalled switch. Well done! You earned my respect!
