With extended use, the main issue becomes apparent — battery life. Buyers who have both radar and light enabled report the device lasts approximately 8–11 hours, which is less than the claimed 20 hours without radar. The radar occasionally shows false positives in heavy city traffic and rarely fails to detect vehicles moving very fast or positioned at angles outside the 45° field of view. Connection to bike computers (iGPSPORT, Garmin, Edge) works without issues.

Complaints mainly concern the plastic seat tube clamp, which some buyers consider weak and unstable — many replace it with their own. Brake signaling and sound alerts cannot be customized. Some buyers also mention that the radar does not respond to vehicles moving within the detection range or positioned at angles outside the field of view. The proportion of critical ratings is minimal (2.1%).
