Don't buy this collar Don't buy this collar. Not user friendly. I never actually used the collars and forgot I had signed up for a multi year subscription. Yes that is an additional cost. Thank goodness my card on file needed to be upgraded so they reached out via email. I responded no to the new subscription especially since I live in Spain where the App doesn't even work. I requested Whistle terminate my subscription immediately and send proof that it has been done and that my personal data has been removed from their databases. Ironically they have frozen my account where I wouldn't be able to access even if I wanted. Horrible customer support, no sense of urgency.

Weak straps, keep getting lost, poor customer service We’ve had the whistle tracker for about 8months, the strap design is so flimsy, it kept getting lost. We’re unable to find it this time - the proximity meter is very very weak. On the website it says to contact the support team in case you struggle to find it and all they said was they can’t help us and the warranty does not cover loss. The app is ok hence why 2stars but save yourself a lot of money and get more solid tracker.

Active English Setter We love Whistle. We have a very active English Setter - both in daily activity, and in the field. Being a numbers person, it is cool to see the validation of his daily metrics. It is also reassuring that we are providing the best exercise, and that he is within the markers for drinking water, scratching and licking. The GPS is an added security, that we hope we NEVER have to use. Strongly recommend Whistle!

Awesome Fitness/Health Tracker for Busy Dogs Bought Whistle collars as a gift for our three grand dogs and their parents. Also got the health/fitness/ location tracking apps. These keep track of WHERE our four legged family members are, what they are doing or not doing and what is happening health and fitness wise on a daily and weekly and ongoing basis. We have our watches and they have their Whistle collars and everyone’s taking a little bit better care of ourselves now that we’re getting feedback. The location trackers are terrific for peace of mind. These sync perfectly with iPhones. Pricey but totally worth it.

I have used multiple whistle products… I have used multiple whistle products and I finally had enough so I'm writing a review. Every time I'm going on vacation or anywhere where I would actually need to whistle it turns out whistle is not working the app is frozen you need to reset the device etc etc basically meaning to keep the device working plan and debugging it once a month. Not to mention the GPS location is so inaccurate if you need to find your dog I hope you can yell across three or 400 yards. Truly a disgrace of a simple device. Stay away Oh and they are not giving me my money back per their contract because my credit card has expired so they are keeping my money as punishment for my card expiring.
