Wired 20-key mechanical membrane gaming keyboard with customizable RGB lighting. - Brand: Razer - Model Name: TARTARUS V2 - Connectivity: Wired Thank you for viewing. Purchased on Amazon on October 20, 2022. The dedicated software is not compatible with Mac, and I gave up after trying to configure it with third-party apps for about half a month. It has been stored in a drawer ever since. I am listing it for sale because I don't think I will be using it anymore. I will clean the surface with alcohol before shipping. Please refrain from purchasing if you are sensitive to used items.
