Sync Drive critical battery

I will come right out and say it-sync up drive damaged my battery. I have a 2014 Range Rover Evoque. My son drives it to college. I bought this device so I can make sure he gets back-and-forth to college safely. After putting this device in this car, after about a month, he kept telling me that he thinks this device is wearing down his battery. On my app it kept telling me at certain times his battery was critically low. I went to the Cadillac dealership and ask them to check the battery and they told me I needed a new one. I ignored my son comments and figured the battery was just bad for other reasons which was hard to believe because it was not that old of the battery.Paid for the new battery which wasn't cheap at the Cadillac dealership. After month again, I kept seeing battery critical low periodically and never mentioned it to my son. He's kept telling me again, I think that device is draining my battery because I'm getting symptoms of a battery low with my vehicles back door and I think it's ruining this new battery. My conclusion after reading this thread this device is definitely damaging batteries. Someone mention you should be removing the device overnight or when not driving but that defeats the purpose of sync ups monitoring if someone bumps or messes with your car, it alerts you -if you remove it then that is a useless feature. We had our sync up for only about four months and the whole time the location of our vehicle was never accurate. My son was in Tampa but the device said he was sitting in my driveway in Clearwater. T-Mobile sync up team continue working and never could correct the problem so I got my money back and gave the device back. Now after reading this thread and of all these complaints I am glad I do not have this device anymore because I would end up buying another battery and down the road who knows what other damages it would've caused. It's definitely damaged our battery. I will contact T-Mobile and see about them reimbursing me for my battery.For some reason this device doesn't work on certain cars and damages some cars batteries.I would just warn anyone who is going to have this in the car or buy this -keep an an eye on it right away to see if your car is going to be one of the unfortunate ones that it ruins their battery. This could be a great device which I was really excited to have but they need to fix the problem that damaging certain cars and also find out why it's not accurate. If they do that I would be willing to buy another . But at this time till they fix these two problems for me I'm going to stay away from this device and look for a better one.I am now hoping that I get reimbursed for the money I had to spend out on my new battery so even though I got my money refunded back for this device I'm still out a lot of money!!!!
