Briliant product. Thankfully didn't have any suspicious behaviour near my property before writing this review, but it tracked comings and goings brilliantly, so should there be any in the future I have great piece of mind.
As mentioned in my title however, positioning is key. I placed to the side of my front door. On the side I initially placed, the signal strength must have been affected by the distance/walls between this and my router, so transmissions were a bit temperamental. But when I switched to the other side, everything clicked into place and worked without a hitch!
I have only run on battery so far. Which is lasting well, only needing a charge every few days.
