Editor’s take
In favor
- Per-channel 24-bit ADC + DC coupling = reference-class signal quality
- Active electrodes tolerate high skin impedance and reduce movement artefact
- Optical-fiber isolation eliminates ground loops and mains noise
- Open-source ActiView acquisition; native .BDF format readable by every major EEG package
Against
- Explicitly not a medical device — research-only
- Quote-based pricing in the high-end research tier
- Acquisition software runs on LabVIEW — older UX than newer BrainVision Recorder
- Top sample rates (16 kHz) are limited to 32 channels
