This product is allowing you to obtain a specific device for a 24-hour duration. We guarantee the functionality of the device for the first hour. In the event of a device malfunction within this hour, we provide a free refund. However, we are unable to offer a refund if the device malfunctions after the initial hour. Please note that we have no control over the devices, and IP rotation is not supported. While some devices may experience temporary downtime, it is possible for them to resume working for an extended period within the 24-hour timeframe. However, the duration of such recovery varies and cannot be assured.
