Honestly, I don't want to track my bike down. A thief who is sophisticated enough to get past my lock is probably sophisticated enough to look for a tracking device, so if I find it, it's probably already parted out or tossed in a ditch somewhere. I'm not going to personally track my bike down (seems dangerous), and the police are unlikely to make it a priority. And if I felt the tracking device would help, I'd probably let my guard down because I have a backup plan.

Instead, I make my bike unappealing to steal. I use a high quality lock, avoid parking where thieves are likely looking, and cover up anything that could indicate any sort of value.
