Purchased at K's Denki in December 2025. There are no issues with the product, but I am selling it because it didn't quite meet my expectations in terms of usability. Includes K's Denki warranty. This is a location tracking tag for Android devices, with a lightweight design of approximately 10g. It's an item finder to prevent lost items. - Brand: eufy by Anker - Model Name: SmartTrack Link - Compatible OS: Android - Size: Approximately 37.3 x 37.3 x 6.5mm - Weight: Approximately 10g - Function: Location tracking
