Definitely the recommend the Solid GPS Tracker – Purchased the Solid GPS Tracking based on positive reviews and couldn't be happier. I'm now joining the positive reviewers! I placed mine inside my Caravan for it's first venture away from home. Set my boundary at home, drove the Caravan out of the boundary and sure enough, an alert came through on both my Mobile Phone and Email. It was also easy to track it's journey. What more do you need?! Would recommend the Solid GPS tracker to anyone contemplating purchasing one.
