I've used the whistle 3 in the past and just upgraded to the explore go.....in dense areas doesn't always get a goid signal, but in the clear it works well. I tried the Fi collar which didn't work, so returned to Whistle go explore.....so far very happy with the service. I only wished it would be faster on notification when the safe zone is breached. Recommend this product to everyone with an escape artist pet.
