Royal Kludge RK84 V2

The RK84 is one of the most popular keyboards in its category. I got the White one with Brown switches. In the box you get the nicely packed keyboard (of course that's what I bought!). 4 additional Brown switches, one USB-C cable and a 2-in-1 Keycaps and Switch puller.

They keyboard has a very charming yet soothing look. The RK brown switches have a nice tactile feeling. The keyboard has its own nice balanced sound signature to start with. The factory lubed stabilizers are also decent one. If anyone wants the best of both world for gaming and typing then tactile browns are the one to go for.
The RGB effects are good and soothing brightness, unlike some cheap RGB keyboards available out there. The RK software gives you total 22 lighting effects and a full per key custom mode, with options to import or export the profile. You can set macros as well. The battery backup is decent with the RGB effects on, but exceptionally great without any RGB effect, though I mostly use the wired mode. I have tested the Bluetooth mode with my Macbook Pro and it works like a charm.
Now about Hardware Corpus, they are exceptionally supportive towards their customers, and most importantly they have immense knowledge on the field of Custom keyboards. If you are unsure of your choice you can contact them with your requirement they will help you to choose the right one.
Very fast processing time, safe packaging and they use a good courier service.

Best keyboard under 6.5k budget, i got the white colour looks sick asf
