What SD cards can I use for my DriveSense Ranger

The DriveSense Rangers are compatible with microSD cards of up to 32GB (for the DriveSense Ranger Duo).  
We recommend using Class 10 microSD cards for optimal performance and reliability.
Using a lower class microSD card may prevent the camera from recording data.
