RK ROYAL KLUDGE RKS70 Ergonomic Split Keyboard, Wireless Gaming Keyboard with Bluetooth/2.4G/Wired, 75% RGB Hot Swappable Mechanical Keyboards Fixed Wrist Rest for Win/Mac, Black

The brown switches are nice, with a thunking sound. The keyboard works fine, and the split is also alright. Overall, the solid keyboard feels flimsy when detached into the split mode.There are some reviews on the app not working or not having enough options. The options are fine for someone who doesn't need to extensively mod the keyboard. I currently do not have any issues with the battery or the overall function of the keyboard.

I love these keyboards, including the aesthetics, comfort and functionality.It has some annoyances that took me a while to figure out. The tilde / back quote key is in a very unusual position.You can swap the caps and remap the keys using their software. However, this software only works on Windows PCs and is very difficult to find on their website for download.The good side is the remapping keys is permanent and you don’t need to be on Windows / use their software anymore.Another downside is that the coiled cable that connect the split keyboard sides uses an unusual and proprietary wiring, even though it has a USB-C connector. I tried switching to several USB-C cables, it just won’t work.But good split keyboards are hard to find, and the build quality is solid, so giving 4 stars.

I'm so happy I decided to buy this keyboard. Many of the split keyboards I have researched seem to have a steep learning curve, a layout that is far too different from what I am accustomed to, and they come with too hefty of a price tag for me to take a leap of faith on them.I figured if I didn't like this keyboard's split configuration, I could always just mush it back together for a more familiar feel anyway, and I greatly appreciate the flexibility, especially if someone else needs to use the computer it is connected to and doesn't want to use the split keyboard style.Pros:- feels well built. Mechanical keyboard.- multiple ways to connect to your computer (2.4 ghz and bluetooth, mac and windows modes)- hot swappable keys- tenting support allows for a more natural wrist position, and this was the biggest deal for me.cons- to control volume or use the media keys, I found that you have to use fn + left control to lock the first row as F keys, then you can use fn + the designated key for whichever media function you wish to use... pretty clunky.- the M1-M5 keys cannot be reprogrammed as far as I can tell- I can't find any software for the keyboard either.- since the keyboard relies so much on special function keys, other keycaps are out of the question for me.Everything considered this is a great keyboard and the pros greatly outweigh the cons. I'm very happy with my purchase.

Update:RK contacted me and helped me with the issue, it was a faulty keyboard and they replaced it.works like magic!Ill start with that it came - Opened and scratched and usedWhich sucks and its hard to say if its amazon or the seller - but i ordered a new one as its sketchy to connect a device with a firmware to you computer and install Chinese drivers.beyond that, i never had so many missed keys, i have to retype everything multiple times and i use many different keyboards, laptops, servers cheap keyboards, mechanical keyboards.what seems to be the problem is some key presses dont register, and sometimes there's a lag or a hang when typing.the lights and all that stuff is nice but i need a keyboard i can type and not retype everything a few times.i did get the brown switches as i used these before.biggest cons:.- used- missed keysi havent got to use it in its ergo form as i was trying to get used to typing on it, but just that was tedious.ill try to reset settings but the missing keys is the most annoying of it all.i dont know what the polling rate on this but it feels slow, my Bluetooth keyboards work faster than that.also i noticed that space, backspace and enter have a of movement and sometimes they dont press even though it went all the way down.i dont know if its only this keyboard or they all do this, but it drives me crazy to be honest.noise level is ok, not too loud which is nice for a mechanical keyboard/i use it wired.
