Review on AULA F3087 Mechanical Anti Ghosting Programmable PlayStation 4 by Carl Durant

No instructions or instructions. The keyboard continuously swings the lights around the board. It's annoying. Made in China and their website do not recognize this model, although it has been available from Revain since February 2021. Sent a request for guidance but no response. If there is no technical support right after purchase, how can you rely on the company? Will it even keep its warranty if it needs to be replaced? Will probably return it soon.
