I have the blackvue (Front and rear) and had problems at the start ............. but they were of my own making (RTFM)
their cameras "prefer" their own SD cards at the higher capacity and this is true as I tried a few - but only the one supplied by blackvue has given no problems ............ also - format the card in the camera not on the pc (although you can, but more often than not when you put it back in the camera it doesn't like it )
resolution at 1020 is more than enough - you can view the footage on your phone (low quality), on the software provided for your pc (low quality) but when you export it as a proper vid ... full HD
as said reliability - I've had no issues, other than my own making
