I had bought the Micro version of iTracker me this model. Decisive for me was the size and thereby guaranteed unobtrusiveness. Now I had this running, because I've got no GPS signal is not very long. Then I discovered this model at a neighbor. Made short in my car, drove off ... GPS signal takes an average of 2-5 minutes (depending on weather conditions and due to my metallized windscreen), but for me abslut ok !! Menu navigation super easy, and shooting just awesome !! Commendable, I would also like to mention the support and the reversal of the Verkäuferst. Therefore, a 100% buy recommendation from me !!!
