## Before you buy

- Battery details are inconsistent: the listing identifies an included nonstandard lithium-ion battery and also claims a built-in 1800mAh battery. Runtime is stated as 3.5–39H for the front and 5–10H for the rear, so confirm which operating modes these ranges cover. The 500-lumen output, 70-metre beam distance, waterproof classification and IPX4 claim are listing claims, not independently confirmed here.

## A good fit for

- Runners and walkers seeking a chest-mounted front light with a rear warning light.
- People who want adjustable front and rear modes and an aimable beam.

## Less suited to

- Those needing a clearly specified battery configuration or predictable runtime before purchase.

## Customer feedback

Aggregate ratings lean favourable, with most ratings in the four- or five-star categories and a smaller three-star share. Ratings alone do not reveal what customers liked or disliked, so they cannot confirm the claimed brightness, fit, runtime or weather protection.
