Review on High-Speed 256GB Micro SD Card with Adapter: Class 10 Memory Card for Android Smartphone, Digital Camera, Tablet, and Drone MicroSD by Cedric Edwards

I bought 2 of these cards for use in DVRs. I returned one of these as when formatted the card was larger than the advertised size of 256GB the camera didn't record to the card at all. I bought a Samsung card of the same size and the camera had no problems. The second card seems to work, but every few days the camera shows a write error and requires the card to be reformatted. I am planning to buy another Samsung card.
