Notice: 1. This product's light is built-in (the battery is not replaceable), and it is triggered by vibration. It will automatically turn off after about 10 seconds.

2. The battery can generally last 2-3 months. The battery life varies depending on how often each person uses it, and the battery life is for reference only.

3. Before the product is shipped, it will be checked, and any lights that do not work will be picked out. Due to unavoidable vibration during transportation, the battery will consume power. If the light does not work upon receipt, it is considered normal wear and tear. This situation is not within the scope of after-sales service.
