Goodday I bought razer blackwidow chroma v2 and I had some problems. Sometimes keyboard are flashing after this flashes, some keys are changed coulours, you can watching this at this video I was write to your support team and made all steps which they wrote me (there are: renew drivers, synapse bla bla bla etc.). It didnt help me. So after that yours support team told that I can replacing the keyboard to another because it is waranty situation. So I was come to the shop they replaced me keyboard to another black widow chroma v2. After all I have Same problem at new one black widow chroma v2. I want to know maybe some people had same problem? Maybe this problem in synapse? PS: I tested all my usb ports and tested keyboard at another PC, I was changed profiles and made new accounts - nothing change - same issue.
