Methodology
Useful evidence before confident rankings.
We separate verified specifications, manufacturer claims, hands-on observations, owner reports and unknowns.
What we compare
Real cost
Hardware plus required service plans over one, two and three years.
Interaction
Audio, treat dispensing, movement, alert behavior and pet-specific usefulness.
Privacy
Storage location, account security, retention, deletion controls and documented encryption claims.
Reliability
App stability, latency, connection behavior and recurring owner-reported faults, clearly labelled by evidence type.
