Based on a forum post, the Magicshine Bike Radar Tail Light has been used since the beginning of the year. The user chose it for its very long battery life compared to Garmin alternatives. It performed excellently during a multi-day bikepacking event, retaining 70% battery after two days of frequent use. The light pairs well with Garmin devices for control. However, the user experienced occasional false alarms in urban areas (likely triggered by parked cars) and brief connection drops about five times a day, which quickly reconnected. Overall, the user finds it satisfactory despite noting the product is not fully mature.
AI Summary
Pros
- Very long battery life compared to Garmin radar.
- Excellent performance during a multi-day bikepacking event; still had 70% battery after 2 days of frequent use.
- Control via Garmin is excellent.
Cons
- Occasional false alarms, especially in towns (possibly due to parked cars).

- Product is not fully mature ('ganz ausgereift').
