## Review summary

TopDirector is praised as a powerful, wireless multi-camera switcher with NDI support and a buy-once approach, making it attractive for mobile productions like churches. However, users repeatedly encounter stability problems (crashes, freezes), partial SRT support (no output), and concerns over accumulating unlock costs. Some report syncing/latency issues and limited onboarding materials. Overall, it offers strong capabilities and cost savings, but reliability and pricing friction temper its appeal until stability and documentation improve.

### Pros

- Wireless, cable-free setup enables fast go-live for mobile productions
- NDI support allows using multiple devices (iPads/iPhones) as sources
- Flexible, non-subscription pricing with one-time purchases and upgrades
- Rich live-production capabilities (transitions, LUTs, background music, intros/outros) for professional results

### Cons

- Frequent stability issues: crashes and freezes, including at startup
- SRT functionality is incomplete: ingest may work but there is no output (limited SRT support)
- Unlocks and in-app purchases can add up and may be difficult to recover after reinstall
- Occasional syncing/latency problems and reliability concerns in networked setups
- Limited onboarding resources/tutorials for setup and usage
