I can't mine to turn off at all even though it's set to shut down after 2 hours of activity. My car, for some unknown reason, provides power to the OSD-II unit even when the key if off. I have to take the Mobley out when I stop for the night to ensure I don't run the battery dead. After it gets it's software update I am supposed to be able to set it to never sleep which I will do once I get the power supply for the house.
I really don't see any drawback yet other than it cannot handle the fastest 4G LTE speeds but does handle the original 4G LTE without issue. That means I am getting 15Mb up and down but maybe I could be getting 20Mb if I had a never device. I am completely OK with that if it is my biggest issue.
