Surprised my Frenchie needed the Medium Size, but great quality!!
Just bought the Medium size for my 17 lb Frenchie. I was adopting and had to order a collar without having my dog available for measurements. I originally thought either the XS or S would fit my dog, but the S (10.5 – 13” neck size) was too tight. I was surprised that I ended up returning the S and had to buy the Medium.Seems like a quality collar, my trainer uses Fi collars with GPS on the dogs she is training. Now that I’ve used the collar for a couple of weeks I can appreciate the elegant design and very high quality and functionality of this collar. This is expensive, but a great value and great piece of mind knowing the gps would help me track down my girl if she gets lost. I would buy this again in a heartbeat & i thoroughly recommend!!

Relief
This collar is a life changer. I’m very paranoid about losing my puppy, so to have this—alongside the fact that it gives me updates about how much exercise he’s getting and more, is helpful. The battery life is nice and lengthy too, I’ve never dropped below 90% because of how long it takes to dwindle away. The size, durability, design and location tracking is just flat out thoughtful. The connectivity is splendid too, especially when you leave the app open for more accurate updates. I promise you won’t regret it.

If You Love Your Dog, Get This Collar
This collar is fantastic. It is the same size as any regular collar and the tracking device is not bulky at all. Great range of colors although I chose the grey and the collar holds up well. I have had it for over a year and it has come in handy on the few occasions my dog got out and took himself for walks. One time I found him about 2 miles away! I never would have found him that time unless he came back in his own. I can’t say enough good things about this collar. It is easy to setup and accurate with tracking.

General points
For all the others i tried i would say that the Fi was the one. If she is with me is almost always perfect. But if she is away i think it usually takes a long long time to update her position.Also the size is much better than other brands that has a huge and heavy bump, Fi is thin and discrete, that’s a great pro.The share feature for dog walkers and pet sitters is amazing, i had her staying with a pet sitter recently and he loved it and said he would suggest the Fi collar to his other clients.

Great for locating dog.
This collar works very well. My dog occasionally likes to wander and this collar is extremely helpful when trying to locate him. I’ve used the flashlight feature a ton for nighttime searches. Only complaint is the subscription is a little expensive, but I think we get our moneys worth.

Great colar
The colar works great and gave me a piece of mind. I highly recommend.

Great Low-Jack system for your pup
Our dog has some pretty severe skin issues and this allows us to keep track of her scratching and licking habits, but also allows us to see how much she’s drinking throughout the day. Will definitely be sharing with our vet at her next appointment. Had a bit of a problem putting the tracker on the collar but with some trial and error we figured it out. Battery lasts well over a week before having to put it on the charger and it charges very quickly so we don’t lose out on a ton of data.

It’s a good GPS collar
I purchased my Fi 3 series collar and no joke five days later not notification pops up inside the app notifying of the new 3+ and out of stubbornness I’ve yet to upgrade. lol.The 3 series has some great features—it’s like a GPS tracker crossed with a Fitbit for your dog. You can easily check the app and get peace of mind knowing your dog is still within your property.My main issue is the slow refresh rate. If your dog crosses the digital fence, the delay could mean they’re already near a busy road before you get notified. From my understanding, the new 3+ should be a lot better but we will see.That said, I’ve tried several GPS collars and Fi is the best so far—especially compared to Tractive, which has terrible notifications.Fi sends both push notifications and SMS texts, which is a big plus for iPhone users since you can set a custom ringtone for the text. I just wish they’d add a “critical alert” option like Tile does, so alerts come through even if your phone is on silent.
