The tracker works as you would expect from a modern product. When setting etc. everything is one as far removed as possible, just plug in, Create Account, and the rest goes by itself. Per site, communication with the dongle or iPhone and the server is working so far always. Intelligent device. Only the charger is too large, the Tracker is not firmly properly so that is interrupted at the wrong lying down the charging contact. Have the contact socket slightly compressed so that it keeps fairly easily. If a product defect, but not made the effort to send back to me is too expensive, the only slight disappointment.
