I strapped my DroneMods tracker on my P2 about 2 1/2 weeks ago and did some testing with it in flight. Worked perfectly. Thought I'd turned it off, but apparently not. This afternoon, I've been getting texts and emails from it complaining about a low battery. I called the number and it showed it in my shop at home, exactly where it's supposed to be. I'll charge it up when I get home. Pretty impressive. If I had "lost" my P2 a couple of weeks ago, it would have been reporting it's location, on demand for all this time. I'm impressed.
