Early whistle fan
I was an early adapter of whistle. Now my device is being phased out, new devices cost significantly more while delivering the same basic function. While traveling have found that the device significantly under performs in rural areas, which is exactly where you need it most being unfamiliar with the terrain. I don't really care about my pet's activity level just about where he is. I'm only buying a new device because I would kick myself if he got lost and I couldn't find him, otherwise there's not much benefit. In rural areas I've started putting GPS tracking chips in his bag, which work significantly better.
