It’s made from durable materials that stand up to the wear and tear of daily dog adventures, and my dog seems comfortable wearing it throughout the day.**GPS Tracking:**The GPS feature is a game changer! I can track my dog’s location in real-time using the accompanying app. The geofencing feature is fantastic, alerting me if my dog wanders beyond a designated safe zone.**Activity Monitoring:**The activity and fitness monitor is another highlight. It tracks my dog’s daily activity levels, encouraging us to engage in more playtime and exercise. The app provides insights into my dog’s activity trends, helping me to keep him healthy and active.**Battery Life:**I was pleasantly surprised by the battery life. With regular use, the collar lasts for several weeks on a single charge, which is impressive for a device with such advanced features. This means less time worrying about charging and more time enjoying walks and play.**App Integration:**The Fi app is intuitive and user-friendly. I appreciate the detailed reports and the ability to set goals for my dog’s activity levels. It’s also easy to navigate, which makes checking in on my dog’s status a breeze.**Conclusion:**Overall, the Fi Series 3 Smart Dog Collar is worth every penny.

Amazing health and location tracker!
Great product for tracking your animals health. It’s amazing all the other things it tracks also! Just like an Oura ring or an Apple Watch, but for your dog or cat. It just does so many things. If you care about your animal, this is a must buy!!

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.

Great GPS feature, weak design on collar snap
For the most part I like this collar and the GPS Tracker, The GPS Tracker feature is great.However, I have had mechanical issues with the snap clamp numerous times.My dog is a 70-pound, male black lab, 7 years old. I live on a farm. We take walks twice a day, morning and evenings. The collar has unsnapped itself 4 times. Two of which were in his bed it came off. The other two times were late evening, losing it in the woods. Not knowing until I get home. Then I’ve had to use the GPS tracker on my phone to go out into the night to hunt the collar. I was able to find it. but the collar is not reflective, and the LED light is very dim. The company I purchased it from is sending me a new collar to try. Just know the springs in these clamps are not that strong.

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!
