Tracker works great it's easy to set up and use.

I need to reset Duke's boundaries further from my house....so that I don't receive as many notices throughout the day. Consequently the battery doesn't last long enough!!

The Whistle GPS tracker works just as advertised. I get much longer on a battery charge than they claim - it's running at least 25 days for me - and you get a notification when it needs charging and when it has finished. I love having the peace of mind the unit provides. My previous dog had gone missing for 3 1/2 days once and it was only good fortune that we got her back since she was injured and behind a fence so the chip didn't help.

Our dog leads a busy life and travels with my husband who isn't all that worried about keeping her close. The Whistle tracker has been such a help to be able to locate her quickly. For me it is peace of mind and for him it's time saving not to have to hunt her down. Great product

I've been using the Whistle on two dogs for almost a year, the devices & app work great!

since i got this ,my dog bilbo has gotten away 1 time and i found him in 7 minutes.he is a master escape artist and would run away every few months ,then more frequently.now its as if he knows i will find him so he doesnt even bother and my yard has no fence in the front yard.he just stays put.this is a fantastic product.

I breed Labrador Retrievers to become service dogs. They are very handsome and expensive dogs who's true value is in the pups they produce for the disabled. Plus, I love them and they are family. I have a very legitimate fear if they are not secured. The three in my home have a nasty habit of running together if they are out of their fence or off leash. Whistle has brought them home to me -- twice now. It is instant notification, easy to access and tracking is spot on! I will NEVER have a dog with out it!

Depends on cell phone coverage for its functionality but does function as advertised. The activity goal feature is a great incentive to 'get out' with your pet. I had some problems which were fixed by a very helpful support team.
