Why Choose This?

Our Adatun team finds the USAMS ZB357 particularly effective for those who frequently misplace essentials. By utilizing the Apple Find My network, it offers a level of global coverage that standalone Bluetooth trackers often lack. The ability to share tracking with family members is a standout feature, reducing household friction by allowing any authorized person to locate shared items.

The device is built for resilience. Its impact-resistant ABS shell means it can withstand the occasional drop or collision with heavy keys. Because it runs on a common coin cell battery, the maintenance cycle is extremely low-touch. Once installed, you can reliably expect nearly a full year of service before needing to swap the battery, which can be done by the user in seconds.

Use case 1: Everyday carry

Whether it is your house keys or a wallet, the ZB357 acts as a digital leash. If you move out of range, your iPhone sends a notification, alerting you before you leave your item behind. This proactive approach saves time and reduces the common stress of searching for misplaced essentials before leaving for work.

Use case 2: Frequent travel

Luggage and carry-on bags are prone to being misplaced in transit. Attaching the tracker inside a bag provides an extra layer of security. Since it is compact and lightweight, it fits unobtrusively into luggage pockets, and the loud buzzer can help you find your bag quickly at busy transport hubs.

How to Use

To get started, ensure your iPhone is running at least iOS 14.5. Open the Find My app, select "Add Item," and follow the onscreen prompts to pair your ZB357. Once connected, you can rename the item and assign it an icon within the app. Replacing the battery is equally simple; the rear cap twists off, allowing you to slide in a new coin cell without professional assistance.
