Check before ordering
Battery-life claims conflict: the summary lists 30 hours or more, while mode examples reference ST-904 rather than ST-904L and include shorter continuous-use estimates. No fixed runtime is promised. Confirm model-specific operating modes, charging time, reporting intervals and standby behaviour.
The supplier describes the device as waterproof but provides no IP rating or permitted exposure conditions. Do not assume suitability for swimming, immersion or bathing. Weight, collar attachment, pet size suitability and complete package contents are not specified.
Setup and responsible use
Follow the current manufacturer manual and your SIM provider’s instructions for activation and configuration. Test location updates and alerts in your intended area. Secure the tracking account and change any default credentials as directed.
For pet use, first confirm the device’s weight, secure holder and manufacturer-approved attachment method. Keep it protected from chewing and inspect attachments regularly. A tracker does not replace supervision, secure containment or identification, and alerts are not guaranteed emergency responses.
Use only for belongings you own or tracking you are authorised to carry out. Follow the supplied charging and care instructions and stop using the device if the battery or casing becomes damaged.
