Copenhagen Trackers Cobblestone GPS Vehicle Tracker - White | Real-Time Car Tracking for Fleet Management & Anti-Theft Protection

I already had one of these trackers and bought some more, during the months these worked very accurately and satisfied. However they all stopped working at the same time ! Called support and the solution was to replace each tracker with a new one (cost 50€) The reason I received was that the battery was flat, however each tracker had indicated in its last update that its had at least 80% battery left ? I fear a wrong adjustment at CHP is at the root ! In any case, not neat to pass on the cost to their customers ! Anyway it worked for <1 year certainly not the 4-6y ....
