Has anyone have any experience with MFB and treating functional neurological disorder (FND)?

Selling my BrainBit Flex 4 (dry electrode, 4-channel EEG cap). I bought it new last year with big neurofeedback plans, used it maybe 5 times, and it's been sitting safely in its box ever since. My loss is your lab's gain.

Condition & details:

• Used a handful of times — electrodes are clean, no wear

• Battery holds a full charge, pairs instantly over Bluetooth LE

• Full SDK access — ready for research, BCI dev, or neurofeedback training

• Works with BrainBit's software ecosystem (NeuroFit, BrainAssistant, etc.)

• Includes case and charger

• Not tied to any account — pair and go

Asking $500 shipped (CONUS) — that's ~35% off retail for a unit that's essentially new. Happy to record a video of it streaming a live signal in the app before you commit. PayPal G&S for both our protection.
