I got my landairsea for a few reasons 1. Keep my auto safe in case itâ€™s stolen or towed. 2. I have one unit in my car and one in my fiancÃ© car. So I know where she is and not have to call, to see if she is doing ok. I feel much safer. 3. My fiancÃ© also knows where I am and sees that Iam ok. 4. I sometimes forget where I parked This help me find my car. Iam totally thrilled with this product. Works awesome each and every time.
