First the Tartarus V2 has issues with several MMOs where keys will get "stuck" and based on googling this has been an issue with other Razer products for 5+ years. While some may have been fixed Tartarus V2 still has the issue 2 years after release.
Second, the Razer Synapse software pack suffers from gamer marketing bloat and requires you to have a razer account to even allow configuring your device.
