Bought it six months ago in GEOTRACEUR installed ds my vehicle with athermal windscreen super signal goes well I took more battery kit 14.90 to avoid having to change every 24 hours (it has a limited range, c is the negative point that I take a star). it works with a free subscription to 2 euros unlimited sms and responds tjs qd I called with the coordinates very précises.Je have it programmed to m that it sends its position by sms automatically every 5 hours and it also works perfectly.
Attention it seems geotraceur have the exclusive right to sell this model in France, so the shipped models of other than by geotraceur forcings are not the same devices ... everyone to believe it or not but there is a doubt on the quality of those sold other than by geotraceur
