Honest and accurate Review. In our opinion this item is not fit for our purpose. The stated GPS range of 1 mile is not achievable and we can only achieve 100 metres line of sight from our home before connection is lost to the collar. Our cat cannot be monitored whilst away from our garden and therefore this device is only useful for historically tracking data for his movement when he returns. The battery life achievable is a maximum of two days on the Pettracer recommended setting and not as suggested of around 4 to 5 days. The GPS positioning is not accurately shown on the map and not generally accurate as it suggests some cat movements which are not correct. Cat and collar became lost for eight days whilst having this product and walk searching by us was the only way to find the cat along with members of our village community helping to track him. This product does not reduce our stress levels whilst our cat is away from home (typically for 24 to 48hrs). Customer Services do not respond to emails (3 to-date so far over 5 days) and collar has been lost now on two occasions, even with the heavy duty strap. When the collar was lost the first time we were lucky to have our cats name and contact number attached to it, and a dog walker was kind enough to contact us. Lost again last night but now with no GPS or Radio signal whilst configured in mobile we have no data to start a search. We are tied into an expensive contract for an inadequate product. Very disappointed.
