RK ROYAL KLUDGERKS70 Ergonomic Split Keyboard, Wireless Gaming Keyboard with Bluetooth/2.4G/Wired, 75% RGB Hot Swappable Mechanical Keyboards Fixed Wrist Rest for Win/Mac, Brown Switches Black

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.

Update: I have decided to keep the keyboard, and retrained myself to use the backquote/tilde key on the right side.I'm upgrading it from 3 stars to 4 stars based on having used it for month or so. The extra star is for several reasons:- Once you get over the problems with the layout, it's a very satisfying keyboard. Good touch, good sounds (almost sounds like they're wooden keys, not a super loud sound and I like it), great feel and key responsiveness.- I haven't had any issues with it since I bought it, other than the right-side lights being static rather than pulsing like the left side. But today, after jiggling the cables a bit, they are now both pulsing.- Maybe most importantly, the manufacturer offered me a refund after seeing my review. Which was nice of them even though I'm keeping it after all.If they'd like to make a programmer/business/finance version of the keyboard, then:- move the `/~ key back to the right spot- make the left M1-M5 keys programmable on Mac- in general, make the Mac support better. Maybe a toggle switch that puts it in Mac mode and swaps the keys appropriately.- lastly, and this might sound strange, but make the spacebar on the left side shorter. Most programmers use their right thumb for the spacebar. Left thumb is for manipulating the Alt key. The large spacebar on the left side makes left-Alt hard to reach with my left thumb, and I have to keep the left half of the keyboard at a weird angle to compensate for it.Some of the function keys work on the Mac, which is nice. For instance, the volume controls and player controls.Overall I still like the keyboard well enough to hang onto it despite its flaws for programmers on Macs (even with the offer for a return/refund).Original review:Good keyboard. However, the tilde key is in the far upper-right corner, and you can't remap or rebind it into the proper location because all of the "programmable" M1-M5 keys down the left side are in fact hardwired. There is no Mac software for this keyboard, period.Also the keyboard shows up in Karabiner as SINO WEALTH and not Royal Kludge. They really phoned in their Mac support. I will have to return it, because I can't be bothered to untrain 40 years of typing ~ in the upper-left corner. If you use the terminal, then you use ~. You will know what I mean.Look, feel, and sound are all quite nice though. And if you don't use the ~ or backquote key by touch-typing, then the Mac bindings are decent. The function keys work for volume and brightness adjustment and muting. And if you press FN + s then it switches to Mac mode which has some other niceties such as putting Alt and Command in the right places. So I give three stars, even though I'm returning mine. I'll miss typing on it to be honest. It's hard to find a good split keyboard.

I must say that I was skeptical going in, but this keyboard surpassed all my expectations. I have loved it from day one. I purchased this keyboard after roughly 2 years of using a split mechanical from a boutique specialized retailer which came with high recommendations and cost 4x what I paid for on this lovely device. With regards to build quality the royal kludge is actually superior to the 4x more expensive keyboard. I thought I was buying a temporary hold over until I could cough up the money for a replacement of my previous device but now I see that the royal kludge is a better fit and have interest in looking elsewhere.

I love it. Switch out the key switches for office use though. I swapped the switches with MX Cherry red silent switches, now it’s quieter then the keyboard my work gave me to begin with.Admittedly it’s a little hard for me to type on right now. Though that’s more due to my hands tendency to wander as I type on normal keyboards, so typing properly is new for me.It takes a second to wake up from sleep mode and reconnect in Bluetooth mode. That’s all.
