Got my first OGT.
Not impressed. Could be because this brand new OGT camera doesn’t always see my brand new micro SD card. First it formats fine but it won’t record. I format it but it never notifies completion. When it won’t record I try to format SD card, it fails.
Also, the zoom is too much for me and my quarter acre.
Not worth the further effort to troubleshoot if it doesn’t fit into my organization.
Definitely worth a try if you have a big piece of land. 
Regular OG regular seems to work fine.
