The good news: Fi is one of the best-known GPS dog collars and keeps releasing new models.
The bad news: Without a membership and Fi’s cloud, the collar does not track anything. Fi is a startup that depends on investors.
If you own Fi
- Keep an ID tag on your dog’s collar too, since GPS depends on Fi’s service.
- Check what happens to your membership if you upgrade to a new collar.
