Fi Smart Collar Series 3 Review

Industry-leading battery life and escape alerts. Is the subscription worth it?

$149 + $99/yr★★★★★ 4.8/5

Quick Verdict

The Fi Series 3 is the gold standard for dog GPS trackers. Its battery life (up to 3 months) is unmatched, and the escape alerts are instant and reliable. The collar is durable, waterproof, and looks like a regular dog collar. However, it requires a mandatory subscription ($99/year) to access GPS features. If you want peace of mind and don't mind the recurring cost, Fi is the best choice.

True Cost of Ownership

While the hardware costs $149, the mandatory subscription adds $99/year. Over 3 years, the total cost is approximately $446. This is higher than some competitors, but the battery life means you're not charging it weekly like other trackers.
