The wrong product arrived, I ordered a blackshark v2 + usb card in the Razer store (razer. Ru website), but a cheaper version of blackshark v2 x arrived. The store ignored both my requests and the requests of those. support. Support gave me a promotional code as compensation, I issued a replacement at the point of issue, and re-ordered the headphones in the iCover store. I received the headphones I needed in the correct time. If you don't want to end up in the same situation, don't order from the Razer store.
