## Description

Product description

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: Great Keyboard - I’ve been using the RK Royal Kludge M75 for several weeks, and it has exceeded my expectations. The typing feels smooth and comfortable, and the build quality is solid for the price. The OLED display and volume knob are useful features, and switching between Bluetooth, 2.4GHz, and wired modes is quick and easy. The RGB lighting looks great, and battery life has been excellent. Overall, the M75 offers great features, performance, and value. Highly recommended!

### ⭐⭐⭐⭐⭐ 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!
