“Worked perfectly, best keyboard I've ever owned. For one hour. After that all RGB turned off, and the main function of the keyboard (Typing), no longer works. I can't type with it, the web launcher doesn't detect it either, just don't waste your money.”

“I am loving this kb, the rapid trigger is solid and the sound is surprisingly great for linear switches. Finally, I can jiggle peek correctly all the time without my kb holding me off. The keyboard looks and feels great!”
