Customer Reviews

I've been a customer since this was in beta as Tagg

Since Whistle bought them out I've had nothing but troubles. The product is not reliable. It comes off the collar and no warning is sent. We leave the safe zone and no warning is sent or its sent hours later. We return to the safe zone and no notice is sent. If you're only using this to track activity it's probably fine. If you have a dog who is a runner it provides a certain amount of comfort that you can track the dog, but I don't trust it to actually be working or stay on the collar. There is no easy way to find it if it falls off in the safe zone. A flashing light or chirp would be so helpful. There should also be a blaze orange version to make it easier to see outside. I'll keep using it because I don't know of a better option, but when I find one, I will switch. On a positive note their service is very good and they have worked hard to fix the issues I keep having. This would be a 5 star review if I could trust it to stay on the collar and update location reliably and quickly.

Got this from work and very pleased

I got this as a promotion for work. My version does not have gps. I was surprised how often we end up using this to keep us more honest about waking the dog. It has helped up stick to a routine. It also has helped me track my dogs patterns throughout the day. My dog has a very typical moving pattern every day. Many times based on the irregularities in her pattern I can tell her emotional state or if someone came home unexpectedly. One night we were driving home late and I could see minor movements over a few hours when she normally sleeps. I could tell she was walking the house anxious for us. Another time her movements spiked hard at a time nobody should be home. Turned out a repair man had come through. It is not perfect but I think for what it is, it does the job.

Sieba's People

This was a promo item at our Vets office to try out. It's now become routine with us and allows us to make sure Sieba is doing fine while we are out and about. We enjoy being able to check up on her busy modes and when they take place. Sieba sticks to her routines of playing / walking / bug hunting as if she clocks in and out of a dog union job. When it's time for anything that has fallen into her routine she as well let's you know. If she could talk and wear a watch she'd be the dog tapping the watch saying "hey you with me here, let's get this done". Great product and it's been fun keeping an eye on how she's doing and how we are doing with her as well.
