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.

Whistle is worth it's price in gold! I truly believe Whistle is one of the best things I've invested in since getting my dog, Dixie Susan. I know daily how much exercise and sleep she's getting. In addition, the updates Whistle send regarding itching and licking are very helpful. Combined, everything really keeps me in tune with my dog. And that's very important to me.

We bought this after a harrowing… We bought this after a harrowing experience where our golden took off for 2 1/2 hours from our yard after being frightened by a hot air balloon. I remain impressed by the cost of entry, tech, light weight collar attachment and overall responsiveness. The data reports on activity, sleep, etc. are a nice bonus and will provide a data driven record of our family pet's health trends and any changes in her routines.

Dishonest behaviour Dishonest behaviour: they have been pulling 95,40 USD every year for 4 years from my card, despite I gave the device back a couple weeks after reception (Dec 2019), due to poor performance. Customer service forced us to download the app in order to cancel subscription but didn't give our money back. A subscription related only to a device that has been given back? There is no service without the device: what did I pay for? This is not honest! Stay away from this company!

This is an excellent product This is an excellent product! It tracks everything to help monitor your dogs wellness. Super easy to use and the support from the company is outstanding. Love getting weekly updates of how my dog did and the daily positive affirmations when we meet our exercise goal is very sweet.
