“I love this keyboard. The sound is slightly clicky and mostly creamy. Super smooth to work on. I’ve also set up the RGB to match my PC ones.”

“Keyboard sounds nice, works nice, the software is a bit of an issue to set up as there aren't any proper instructions but you just need the drivers and the VIA app.”
