“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.”

“Although it is very pingy out of the box, with a few quick customisations it will sound amazing. Shipping isn’t that quick tho, with slow and outdated updates.”
