Conclusion

Now the better device between these two is still the Fi for us. Now you may ask, why is Fi better when Findster is already free and offers similar features? Our humble opinion is that Fi has better tracking quality due to the latest technology they are using, the LTE-M network, for better precision and accuracy to locate your pups. The battery life of Fi is evidently longer-lasting and makes it more efficient than Findster Duo +. This alone made us firmly choose Fi instead.
