I just had my worst customer service experience with Razer today, so I'm here to try to have proper help. First of all I want to make clear my loyalty to Razer so far and this are the product I own from them today! Razer Blade 14 touch screen, top of line Razer Nari Ultimate Razer Blackwidow v2 Razer Mamba Tournament Edition Razer Hammerhead v2 Razer Orochi Razer Atheris Razer Goliathus Overwatch Edition Razer Goliathus mobile Razer Base Station Chroma Razer Leviathan Mini With that said. My Nari Ultimate started yesterday to fail, while playing I started to hear some 2x beep, like Beep Boop, the audio coming and stop,then disconnect. I thought it was battery, but the phone was fully charged and I got error message of device disconnect from Windows. I did full uninstall of Synapse 3, uninstalled removed the folders from ProgramFiles, AppData, ProgramData, went to Registry, removed everything from Razer and THX, rebooted verified everything again to make sure I had no Razer files at all on my computer and installed Synapse 3 again, same problem after few minutes with it working. I changed the USB port and started working again but same problem, beep boop and then gone. Moved from my PC to my Razer Blade, same thing. Got in touch with Razer, instead of helping or sending a new USB Dongle, they said they can't do anything I should talk to my retailer. I live in Brazil and I bought this headset in Germany from Staturn in Frankfurt. I can't go there and ask a new headset, Razer has official presence in Brazil, I checked and there's people working here on LinkedIn, they sell official store from mercadolivre.com.br, at fasthop.com.br and many other places, they could help a loyal customer, but they give their back ! It's so frustrating ! If anyone can help I really appreciate! Thanks !
