Perfect size for a rear cam. Downloading using app (Bluetooth) is painful. Takes forever to connect or does not connect at all. I’ve been using it for 2 weeks+ now, but haven’t been able to upload to the vault (even after incident/save video): but using phone network connection (not wifi); that’s an option available to configure in the settings. It does not work. I have a tandem and mini2 in my car and it all syncs in well. I still recommend it, it’s a good piece of technology, it works for the basic need of recording and works well.
