Review on 📷 KOOTION 64GB Micro SD Card: High-Speed Class 10 TF Card for Smartphone/Bluetooth Speaker/Drone/Camera/PC/VR by Matthew Riley

These cards seem like pretty good value for money at first glance, but after a few hours in my car DVR both cards failed miserably. constant heavy-duty inherent to DVRs, but these cards also refuse to be formatted with the device. These cards are falsely advertised when the packaging says they are DVR compatible. Not worth the money spent on them if they fail at the crucial moment. My advice: invest a little more money in a branded high endurance dash cam card. I will return them for a refund.
