Review on Ti-6000 Live 3G GPS Tracker: Portable, Long Battery Life, Magnetic Mounts, SIM Card Included by Larry Morris

I would say this is the best GPS tracker in terms of price/quality. It comes with a SIM card and all you have to do is activate your subscription and you're done! Support is quick via email (you'll have to tell them to turn on roaming if you're outside the US). The tracking is so accurate it shocks me (in 15 second intervals) and it has one of the longest battery lives of any device (10000 capacity if I remember correctly). It also has a compact size with a super strong magnetic body. In general, there is nothing to complain about with this product! Highly recommended!
