Our Testing Experience
First Impressions
When I first got the Fi New Series 3+ Smart Dog Tracker Collar, I was really curious to see how it worked. Putting it on my dog was easy, and the collar felt lightweight and comfortable. Setting up the app was straightforward, and I appreciated that it connected quickly. I was excited to try the GPS tracking and see if it really could give me accurate location updates in real time.
Daily Use
Using the collar every day quickly became part of our routine. I loved how the app sent me instant alerts if my dog wandered outside the safe zone we set up. One time, my dog slipped out of the backyard gate, and I got a notification right away. The collar’s LED light was also handy during evening walks, making my dog easy to spot. I checked the health and behavior data often and found it interesting to see how much my dog was resting or scratching during the day.
Key Features in Action
The escape alerts were definitely a lifesaver. Knowing I could get updates every few seconds when my dog was roaming gave me peace of mind. The GPS tracking was impressive — it worked well even when we were out hiking in areas with spotty cell service. I also really liked the health monitoring feature. It was cool to see the collar detect when my dog was eating, barking, or being active. It helped me understand my dog’s habits better and spot any changes early.
Long-Term Performance
After using the collar for several months, I can say it held up well. The battery lasted as promised, and the waterproof feature saved me from worrying during rainy walks or when my dog jumped into the pond. The app stayed reliable with regular updates and no major glitches. Overall, the Fi Series 3+ collar proved to be a trustworthy and useful tool for keeping my dog safe and healthy.

Worth the price!
I love this thing! My dog has been wearing it for 4 months now. I just wanted a tracking collar for my deaf dog for when she sometimes escapes the house/yard and got a lot more than GPS tracking. It tracks her step, scratching, barking, eating, licking, sleeping, drinking, everything! The tracking update is very accurate as well, notifies me the second she leaves the house. It’s not super heavy at all, feels like just a normal collar.My only complaint, the base for this thing always disconnects like once a week. Nothing dramatic happens when it disconnects, just loses battery faster, but a little annoying to keep having to reconnect

Amazing battery
Best one out there. A lot smaller than the last one. Definitely recommend. I’ve had no issues with the positioning accuracy or disconnecting. Love the charging base.

Inaccurate GPS; not reliable for rural areas.
I’ve been exceedingly hopeful about this product for a long time now. When it connects to GPS, it’s helpful for at least getting you in a general range. It does not accurately let you know when your pet has left the safe zone at all. It also does not pinpoint your dog’s location on GPS; it only shows a general location, so you could be 500 to 1000 feet apart, which is a very big distance if you’re in a forest or field without a clear line of sight. It can take 45 minutes to get a notification that your dog has left the safe zone, depending on when it picks it up on GPS. The battery does last a while, but nowhere near the three-month claim. It is sturdy and it does stay on, however. The point of the light I don’t quite understand because it’s not bright enough if you’re looking for them at night. I think it’s just a fancy added feature. The subscription part, where you can see all of the steps that they take, is not really a bonus, the way I purchased it. It was part of a package deal, so I’m not sure if I have to keep it yet. I certainly don’t plan to because it won’t be worth the money for what I’ve gotten out of the product.If you’re looking for something that is going to immediately tell you when the dog leaves, give you a small area, as in less than a third of an acre for a safe zone, and pick up GPS signals in rural areas, you’re going to need to spend a lot more money or find a better product that I may not have found. This is not meant for rural areas or anywhere that has gaps in GPS. You’ll just be hunting for your dog for hours, walking in circles, playing chase, hoping this thing actually leads you somewhere.

If you dog is less than 40 lbs, consider the Mini…
I like the collar and tracker.The step counter is an effective tool for getting me to walk my buddy religiously. We now aim for an ambitious target and she is very enthusiastic about our long walks. (I am happy for her — and have already dropped a few pounds, myself.) So… gamification of walking is very positive.Accuracy of tracker is OK. The GPS feature shows individual walks, but the accuracy is good to only a few hundred feet. I’m a little worried about how effective my search attempt would be if my buddy runs off. So… accuarcy is OK.Sizing is a little limited. I probably would opt for the “Mini” next time. My buddy is 35lbs and the one-size-fits-all collar is too wide. That suggests that I should take it off inside the house, but then she might accidentally be let out without it. So… sizing is too likited.

Este producto no sirve fuera de estados unidos, gaste mucho dinero por él, pero la aplicación no tiene cobertura en mi país y trate de regresarlo, pero Amazon no pudo ayudarme y las paqueterías locales se lavaron las manos además de que por parte del vendedor no me proporcionaron un número de guía válido, desafortunadamente tuve que quedármelo, la peor experiencia de compra que he tenido, si eres de México u otro país NO COMPRES este producto!
