Review on High-Speed 512GB MicroSDXC UHS-I U3 Card For 4K UHD Video Recording And Monitoring With Adapter - Ideal For Dash Cams, Body Cams, And Security/Surveillance Cams by Bradley Stewart

I initially bought this card for a Vantrue 4K dash cam. I sold the camera and replaced it with a BlackVue DR900S with front and rear camera. I transferred this card into the BlackVue, formatted it and it has run solid ever since. I'm running both cameras at their highest resolution (4K front, 1080P rear) and have had no issues with heat or read/write speeds. This is a good, reliable card at a reasonable price. I highly recommend it for 4K dash cams and similar applications.
