Review: Max visits the Women's Book Club - My dog Max is a bit of an escape artist. The last time he got loose, he wandered into a neighborhood women’s book club, where he acted as though he were starving and was promptly lavished with food and attention. It was a funny ending, but it also made me realize that I needed a reliable way to find him quickly if he ever escaped again. Choosing a GPS tracker was not easy. There are essentially three major brands in this category, and Fi appeared to be one of the leaders. After reading through a great many reviews, I chose the Fi Series 3+ because it seemed to have the fewest one-star ratings. More importantly, many of those negative reviews appeared, when read carefully, to involve setup mistakes or user error. With some competing trackers, the negative reviews seemed more likely to point to actual problems with the products themselves. My Fi Series 3+ Smart Dog Tracker Collar arrived within two days. I was immediately impressed by the packaging, which was right up there with what you might expect from an Apple product. The instructions and setup process were equally impressive. Everything was so clear and precise that I was able to get the tracker working without having to backtrack, reread anything, or troubleshoot a single step. That is certainly not the case with many technology products, and it demonstrated the company’s attention to detail. I prepaid for 12 months of service so I would not have to think about monthly payments. I was also pleasantly surprised to see that the Fi app had a 4.7-star rating in Apple’s App Store. I then added the App to my wife’s phone. After all, if Max escapes again and crashes another women’s book club, I want both of us to receive the alerts. Her phone paired with the tracker quickly and easily. The most challenging part of the entire setup was attaching the tracker to the collar, and even that was only because the attachment mechanism is extremely well made. There is a spring-loaded flap that is the same color as the latch. After removing the small protective plastic covering, you need to flip open the spring-loaded latch before sliding it over the tracker. Once you understand that, you are off to the races. The next step was testing it. This was especially important to me because the most common complaint about dog GPS trackers in general is that they supposedly fail at the exact moment you need them. I left my phone in the driveway, told my wife where I was going, and walked down to the end of our cul-de-sac carrying the tracker. When I returned about two minutes later, my phone had received two notifications: one when the tracker passed the end of the driveway and another when it reached the end of the block. Both notifications included addresses, and both locations were perfectly accurate. My wife’s phone received the exact same updates. She was impressed, I was impressed, and I believe most buyers will be impressed as well. Spending a little less than $200 to help ensure that your dog does not end up lost—or become coyote food on some random evening when he decides he is in the mood to explore—is money very well spent. So far, I am extremely pleased with the Fi Series 3+ and feel much better knowing that, should Max make another great escape, we will have a much better chance of finding him quickly.
Review: Extremely disappointed - Absolutely terrible experience. I could activate the tracker, but then I was effectively soft-locked out of the app because it couldn’t figure out how to apply the membership. It took me to a blank screen with an error message and no way to clear the error except to uninstall/reinstall the app and try again. The AI chatbot was useless. It declared that my issue was resolved simply because I was able to activate (but not actually use) the tracker. It did eventually escalate me to a human via email. I provided screenshots (attached here) showing the error and how I was locked out of the app. The best they could say was that they’d pass it along to their software team to investigate. So I’m returning the product. The app is terrible for creating a soft-lock in this situation. They really didn’t anticipate that someone might need to access parts of the app without an active membership? Customer service was not helpful. I don’t trust this product to help if my dog gets lost.

## Features

- REAL-TIME GPS TRACKING, NO RANGE LIMITS: See your dog's live location nationwide in the Fi app. This GPS dog tracking collar runs on nationwide cellular and GPS coverage with 2x improved GPS performance over earlier generations, so it keeps up on trails, at the park, on road trips, and anywhere else the day goes.
- 12-MONTH MEMBERSHIP INCLUDED, NOTHING EXTRA AT CHECKOUT: One price covers the collar and 12 months of Fi Membership, the GPS and cellular service plan that powers it. No activation fee, no added hardware, no separate signup. Unbox, pair with the Fi app, and tracking, escape alerts, and health monitoring work the same day. Membership renews after the included 12 months to keep GPS service active.
- ESCAPE ALERTS AND LOST DOG MODE: Draw safe zones around home, the yard, or a sitter's house and get an alert the moment your dog slips out. Lost Dog Mode switches to rapid live location updates so you can follow their path and act fast. The whole household can share the app, so everyone is alerted together.
- AI HEALTH AND BEHAVIOR MONITORING: The Fi app counts steps and tracks activity, sleep, and rest, and detects behaviors like barking, licking, scratching, eating, and drinking. Long-term trends make it easy to notice quiet changes in routine that may be worth a vet conversation, and weekly goals with breed comparisons keep daily activity on target.
- BUILT FOR REAL DOG LIFE: A stainless steel frame, IP68 waterproof rating, built-in LED light for night visibility, and wireless charging stand up to daily wear. Check live location and activity right from your Apple Watch, and ask the built-in AI Companion care questions, with vet visit and vaccine reminders plus uploaded health records organized in one place.

### ⭐⭐⭐⭐⭐ Great collar!
*by T***S on May 19, 2026*

Love this collar! I have a beagle who is an escape artist! He’s had it for about a month. Last night he got out of the fenced in yard . The app on my phone immediately alerted me to the situation. It gave me his location. He was heading back to the house when I got him. He was hurrying because his collar was flashing a white light! No more lost dogs! Highly recommend!
