i put it under the car and everything worked perfectly, but after just 4 days of use it stopped working. first i thought it was just the battery even if it signalized me 30 %. than took a look at the tracker and saw that the control panel is all of rust and wet inside. its all damaged, i cant even remove the sim card now or charge it. ITS DEFINITELY NOT WATERPROOF!!!
It still works. If there will be a lifetime version of the program I will be satisfied :)
