This is brand new in box, still sealed and never opened. (The pic showing the items is from another that was opened). Includes whistle device, USB, and instructions. This device needs the whistle app to work and I believe they charge a subscription fee. This is not the GPS version. -The Whistle Health smart device helps you understand your pet's health by monitoring common pet health behaviors like licking, scratching, eating, drinking and sleeping. It is the go-to resource for providing better care for your pet, no matter their age, breed, or temperament.

Comes with: attachment strap, micro USB charging cable, and a quick start guide. Bluetooth connection to a mobile device is required.
