To be honest, I used the device to catch my husband activities and Iâ€™m gonna tell you what this tracking device benefits me! I had a doubt that my hus was cheating on me when I gave birth of my first child and I did some researchs and found out landairsea tracking device that is supporting with a waterproof botton option. I put it in his car inside the back tire tunnel which nobody would see and I swear that was the best thing ever! I found out where heâ€™s going and parking his car, I found the place of the girl that he was cheated with on me! Also, where they go it was updating per 5 seconds and Iâ€™m gonna tell you , itâ€™s literally a life saver, I used it for 8 months charging it once a week! Iâ€™m living in Seattle whichâ€™s rainy most of the year and the device was working pretty good without effects by the water! Thanks for whoever discovered it and save my feelings and my time! I highly recommend if you been through the same doubt feelings!
