### 5/5 — Awesome

*2025-06-11*

I felt safe running with the light because the park where I run at is very dark. People noticed I was at the park running with a purpose with the light and not a person you can’t see in the dark.

### 1/5 — Horrible app. Is not effective at all.

*2024-12-23*

The lights are not effective patterns. Does not utilize enough brightness. Would not help safety at all when running or biking at night.
