Thank you for viewing. Razer BlackWidow Elite Junk item. Several keys have become faulty, so I replaced it with a new one. Perhaps for parts, such as disassembling the keyboard for research, using keycaps, or transferring the key switches to another keyboard. Recommended for those personally interested in this product. ★Please consider only if you understand that this is a junk item. ★I have a cat.
