Consumer neurostimulation should be reviewed more like a medical-adjacent intervention than a gadget, and any experiment needs stop conditions before performance claims matter.

Unfair does not sell Halo Neuroscience hardware. This review is educational and based on public information about the device category and transcranial stimulation research, not a clinical recommendation.
Methodology
We score the product category on claim severity, published human evidence, risk controls, user-screening needs, and whether a home user can measure a meaningful result without unsafe escalation.
| Criterion | Risk-first read |
|---|---|
| Claim type | Motor learning and performance claims need human controlled evidence |
| User screening | Seizure history, implanted devices, pregnancy, and neurological disease matter |
| Protocol control | Placement, session duration, and intensity must be fixed |
| Outcome | Skill acquisition needs repeated testing, not one exciting session |
| Support | Clear contraindications and adverse-event guidance are required |
Decision criteria
Do not use consumer brain stimulation to self-treat TBI, depression, ADHD, seizures, migraine, cognitive decline, or neurological symptoms. These require medical review. For performance experiments, the only defensible path is conservative, protocol-bound use with clear stop rules.
Safer evaluation protocol
| Step | Rule |
|---|---|
| Screen | Review medical contraindications before use |
| Baseline | Track the target skill for 2 weeks |
| Active | Keep placement, duration, and training task fixed |
| Outcome | Use objective skill metrics |
| Stop | Headache, skin burn, dizziness, mood change, seizure-like symptoms |
