Safely store your valuables and bring them with you anywhere with the Nebula Star Portable Safe Box. This device offers infinite storage space and keeps your valuable belongings locked up until you want to access them. Lightweight and portable, with the latest NB-IOT, you can track the safe anywhere and everywhere. Unlike GPS, NB-IOT fully covers outdoor, indoor, and underground, and its range is 100 times wider than GPRS. You can track it down with its exact location no matter where it goes. Download the app, register your device and add fingerprints to ensure that you are the only one with access. In addition, the app connects via Bluetooth or WLAN, enabling you to unlock the safe remotely. Likewise, you can use the app to track safe usage, add or remove fingerprints, change the LED band color and more. The Nebula Star is tough and durable, featuring high strength aircraft aluminum alloy that can withstand over 24,000PSI. It’s even been tested to handle the weight of a car driving over it.
