My partner and I have bought several Tabcats off you guys and we rave about them to everyone we meet. Last night my cat wasn't coming in for "curfew" so we got in the car with the tracker and actually found him miles away from our house where I'm sure he was having a grand adventure.
I volunteer for a rescue shelter here in New Zealand where our focus is unwanted, abandoned and community cats and kittens. We have a lot of situations where cats are still getting used to their new homes and get "lost" aka, they've found a space in a wardrobe or area the new owner cannot find them and they panic
To be completely honest, that was only one example of about 500 why we love your product so much.
