The Ugreen CM817 Bluetooth tracker has a slim, card-shaped design and connects to the Apple Find My app to help locate items. It uses Bluetooth 5.2 with a range of up to 10 m and works with Apple devices, but not Android. It can be placed in wallets, bags and suitcases.

The built-in rechargeable battery charges magnetically and provides up to 12 months of use on a single charge. The speaker emits a 75–80 dB sound to help locate the item, while the Left-Behind Reminder feature sends an alert when the tracker moves away from your phone. Location information can be shared with up to five other users running iOS 17 or later.
