Before I panicked (it is not a very cheap device after all), I decided to go to the Whistle web page and started browsing for some answers

The Whistle collar is designed well enough to be confident that the dog's not going to lose the device

Fantastic device

This little device has simplified our lives so much!

Overall, I think it is a neat little device that has been beneficial for our dog

- it has been confirmedI have been working on this for over 1 month of troubleshooting and going back between Whistle and Assus this device is not compatible with ASSUS routers

The device itself was sturdy, waterproof and stayed clasped with the double locking rubber strap.

I thought, the last time I tried to detach the device so that I could charge it, that I simply would not be able to do it.....in which case, the device would have been absolutely useless

Overall, if you want to ensure your dog is getting enough activity to stay happy and healthy, this is the perfect device

When this happens you run the risk of losing the device rather easily.

I love this device and I think this gadget could end up being a smash hit.

Great device, works well automatically communicates.

Great device, works well automatically communicates.

The device looks chunky on my 25lb dog, as you can see in the picture

The device is very easy to install on a dogs collar and initial setup is quick and painless

I would go for a 30 minute walk and the device would register 10 minutes....again, major inconsistencies.

I have this little device now for almost 3 years, and it still works very well

Customer support has been wonderful though, extremely responsive, promptly replacing each dead device.

This device is so neat to track my dog's activity

It is not a great device if you have dogs in any other situation or you simply want to ensure their safety.

For now, the Whistle is fun to have but ultimately this device can be better, and more useful, if additional features are added.

awesome device - LOVE IT

Overall a great device.

Normal use has destroyed this device in less than a year, and for a device that I originally paid about $140 for, that isn't acceptable

I received a new whistle and returned the defective device.

Of course there are bugs to work out and lots of changes I would make but for the first version it is an amazing little device

The device is small (as you can see in the picture), and sturdy

Perhaps this is a great device if you have a small dog, live in an apartment, spend your time on social media and like to go from one menu to another

Like my fitbit, I wanted a device that did not need to be constantly charged, and the Whistle battery lasts approximately 10 days.2

In general, if you have realistic expectations, it is a good device for knowing roughly where your dog is and, if you're lucky, precisely where he is.

I really question the utility of knowing this info...but I won't ding the device because I personally am not totally into its premise.

That was stellar customer service and a great devices.

Absolutely love the device as it keeps me more in sync with the amount of rest and exercise my dog needs

This is a fun little device and it is interesting to see how much my dog moves around during the day vs. how much he sleeps

The Whistle app has a built-in feature to remind you to give medication to your dog at any time interval (daily, weekly, monthly, etc.).Overall, the device has been much more helpful than I imagined in helping me make sure my dog is living an active, healthy life, with some added side benefits that make taking care of him on a daily basis much easier and fun.

We've lost the $100 whistle device so many times and had to find it out in the yard because of this.

When the vet said one could lose some weight I upped his goal by an extra 10 min/
